I use it with 11-34 for cx and with the tension screw almost completely unscrewed to get a proper distance between upper pulley wheel and the 34t sprocket

I just run a 10 speed zee rear mech with 11-36 and 46 narrow wide up front, on a carbon focus with bullhorn bars and bar end brake levers. made a custom mount for the zee shifter just beside stem. Been going strong for 3 years on my roadbike and i give it hell on singletrack.
In future videos it would interesting to explore how you can upgrade/ simple hacks with GRX components into exisitng groupsets if you are on a budget. For example can you upgrade the chainrings from an existing Tiagra 50/34 to a GRX400 46/30 easily - or do you end up needing to change the FD, RD, chain and BB as well? Then you might as well add in the shifters!! Then up mights as welll upgrade to the 11 speed GRX600 - one of the kids is going to have to drop out of university so I can pay for this!!
I've tried that already and I can tell you that you could do what you asked about if the bracket for the front mech installation allows the mech to move down to accommodate smaller chainrings. In my case I changed from 50-34 to 48-32 and the bracket on my carbon frame did not allow the mech to move down enough for a crisp gear change. Because the bracket was fixed in the frame I had to remove some material from the lower part of my bracket so that the mech would slide to a lower position (about 1mm lower). Wasn't the most elegant solution but that made shifting very good. if you have an alloy frame you could have the bracket installed with a collar which will allow you to move it wherever you feel. Carbon frames tend to come with brackets installed in carbon and moving them is impossible without a major carbon operation which is very dangerous for the frame.
@@vaynomblenner I have tried this little part or a similar one, the problem with the one I tried was that it worked for chain-rings smaller than the ones I wanted to use. The part I've tried was not suitable for such a small difference between rings, 50 to 48. After adding the adapter part the highest position of the mech was too low for a 48 chainring even though I pushed the mech and the adapter at the highest point possible on the bracket.
I built a bike around a bombtrack frame and a mix of grx compontents. 600 shifters & 2x crankset, 800 derailleurs and 400 brakes with ultegra rotors. So far I have ridden it for 200kms and the performance is very good! Better shifting than my 105 5800 on my road bike. Brakes are unbelievable as you'd expect from hydraulic brakes. Some things to note: The 800 series shifters offer a feature where you can adjust the stroke of the brake lever and the different pivot point is only availbale for di2. Dont try to mix 2x on the front with 1x components in the rear. The articulation of the rear derailleur is different and there is not enough tention on the chain. I would try a wolftooth extender for the 2x rear mech to make it for more gears for uses like touring where you need some extra low gears.
I just changed my 105 setting on my Giant Revolt for the GRX600 shifters coupled to GRX400 disk brakes. And now that i will make a 3 day bikepacking across some Algarve mountainous backcountry (its almost like a roller coster), and since I´m on the heavy side, just changed my rear cassete to a 11-40 Slx and just put an extender om my 105 rear mech, and its working fine till now ( crankset is a Praxis Alba 48-32). I really like the Grx shifters feeling.
Thanks for the video. I was actually very excited about this groupset, since I'm building a gravel bike. But there are some underwhelming points: 0) discs are only hydraulic and I just hate that, because, while it's true offer have better modulation, they are still difficult to set up and if something happens in the field, it's game over. And this all comes at double the price of a mechanical set of very good mechanical discs. 1) The RX800 long rear derailleur, aside from suspiciously looking like a Deore XT piece with GRX written on it and (maybe?) different cable pulls, it's stupidly expensive compared to the XT and SLX homologous, even if you count the cable pull converter. I did not yet see anywhere an RX600 RD, and the big fat RX800 is the only one that can go up to an 11-42 cassette. I'm a big Shimano fan, but the GRX doesn't do it for me: I went for 105 STIs and FD with an adapted SLX, 11-42 cassette and a double 46-36 chainset at the front. Shimano's mechanical calipers onto Shimano discs. All in exquisite silver☺️. P.S.: those bits are for sale since a while now... With prices. When did you record this video?
Actually don't be afraid of hydraulic brakes. I've ride them very abusive on mtb- and also on long brevets 400-600km. They don't fail. Regarding rear derailleur, I'm using 105 medium and it works fine with 40 cassette. But you can add an adaptor it's 5usd on ali. if it's not enough. Not sure about the price of Ultegra with clutch derailleur. Guess the main gain here is the brakes leavers.
Oleg Revulet That's good to hear. I also have them on my MTB but not since long. I must say I didn't really enjoy setting them up with the mineral oil and stuff... And, also, the levers I have don't offer that much adjustment (but I guess this depends on the specific model). One big difference between MTB and road hydraulic discs is the price: hydraulic STIs are still exactly twice the price of mechanical ones. And usually bigger... Yes, I agree that the main point of the GRX may very well be the top levers (still eye-watering expensive compared to their mechanical counterpart). It's very interesting what you say about the 105 RD, which I guess extends to the Ultegra RX. I went for the SLX because I was after a RD with a clutch and, with the Jtek adapter, came away at around the same price of the Ultegra RX while not requiring an extender, and was still cheaper than the GRX810 --an XT plus adapter would have costed the same but, as you might have already sensed, budget was a very big consideration with this bike.
2020 trek dual sport 4 hybrid bikes use the same gearing as your test bike. We threw on some 35c tires from the standard 38c for a bit better on road performance but still keeping that gravel ability. Gravel is here to stay. I'm glad because we have more gravel paths than tarmac paths. Wouldnt mind drop bar option on the dual sport 4 though.
Oh yes, a Shimano dropper Seatpost. That is what the world needed :-D . It is just to much stuff out there and I wish they would just make fit MTB and Roadbike components fit again like many many years ago. Thanks for that review.
The only upsides here over ultegra/105 would be that brake lever leverage thing, but also not completely sure on that, since we already are hydraulic, not cable actuated. 2x with smaller rings and official acceptance of 42t at the back.
Calling it the “worlds first” gravel specific groupset is begging for people to start thinking about SRAM’s 1x offerings and realize that the only way that Shimano can make this claim is by splitting some very thin hairs. They ought to be honest and say “here’s our gravel group, we think it’s pretty good” and not insult our intelligence by making silly marketing claims.
I have recently installed a grx fc-rx400 46/30 2x crankset on a bikenstein build that has sora r3000 shifters and front mech. By unwinding the outer limit screw, and properly tensioning the front mech cable, I could get them to work together flawlessly. Shifting is spot on, and I get no derailleur rub. Front trim is somewhat limited though, but it’s nothing unbearable.
There should be switch for lights also integrated on levers.. Because it's adventurer bike, you need to change light settings from hi beam to low beam or intensity of light, but sometime you can't take hand off from handlebar to do that. In snow or mud or sand or something and then you have no choice but to dazzle all oncoming traffic because you just can't, without stopping at least.. but then it can be challenging to restart once you have stopped on bad road.
Pretty cool. But I wish that lowest gear on the1x would go up to say 46 or 50 rather than just 42. I'm really more interested in lower gearing for long steep climbs.
It is sad to see Shimano noticed just in 2019 it is safer to brake reliably. And also the fact I configured 3x9 road casette with MTB crankset to have wider range and tighter stepping than newest/coolest GRX says something whether Shimano really did their homework.
Considering the same setup on my 2020 crockett to replace the Apex it came with. Though on road I wish it were more like a 44 or 46 with a bailout gear in the back. 11-40?
I just want that new RX400 rear derailleur for my Tiagra equipped gravel bike. The fact that this is already 10 speed compatible makes me so happy to have Tiagra 🙂 It's nice to see Shimano looking out for us bike peasants and not just the performance segment.
been using the 30-46 grx crank for a month or so already both with ultegra 6800 and 105 R700 on different bikes...and it works like a charm. The swap of front derailleur is a nightmare tho. I wish shimano will bring out a 105/ultegra crank with 30-46 for the "big boned" riders :)
I understand your concern and in theory the oil from his fingers will reduce the breaking power but from my experience it doesnt really matter so much.
@@arneseys4729 true true When ever i get the squealy noises i take a sharp object like chisel and score my rotor with that. The burrs from the scratch are enough to remove the contaminated breaking surface. Pretty ghetto but thats the only method i found working.
As a GRX owner that came on my gravel bike (Whyte Gisburn v2), here's my thoughts... I like 1x (I have SRAM Eagle 1x12 on my MTB). I love the GRX feel. I love having a dropper post as the left lever paddle. I like the brakes. I like the idea I can add the in-line mini sub-brake levers down the line as an upgrade. So I'd take GRX over SRAM for gravel. With a 38t chainring (it came with Easton cranks and 38t ring) it's fine for off-road stony hills and I wouldn't like much bigger a chainring else if I've got bikepacking luggage, or if I just wanna go up extra steep stuff, I wouldn't be so happy getting up there. But the 11t with the 38t combo can get a little spinny on smooth tarmac or downhill. So I just fitted an XD driver and SRAM 10-42t cassette. That extra 10t makes all the difference. I love it and it now seems perfect for what I want it to do. So I think where Shimano “got it wrong” with their 1x IMHO, is for the best balance it needs a standard 38t chainring available and (I guess with their microspline freehub) a 10-42t. 11-42 is fractionally too slow in the top with a 38t for my liking, but would undermine the climbs with a bigger front ring and the 11-42. Else keep the bigger chainring and have more teeth on the low end of the cassette to give the wider range. Obviously this is personal and depends on terrain and your legs, but for me, using it as a regular commute mostly on tarmac, and adventure bike all over the place in some pretty gnarly off-road places (and the fun bits of the commute), 1x systems with 420% cassette range just plain make more sense than 380% range.
Since I'm back here replying to my old comment anyway: yes, I did also buy the in-line sub-brake levers too in the end. Still very happy with it, and still very happy with my swap to a SRAM 10-42t cassette and XD driver freehub instead of of the original Shimano 11-42t (albeit I've already munched through one and on a second the amount I rode it in all conditions).
GCN is succeeding. I never thought much about Orbea, but after some of these videos I have started to consider those as alternatives. Fortunately my bike shed is full now. I think that if I bought more there would be danger that some room would be freed in the master bedroom...
had 2 rides on my gravel bike with GRX mechanical i like it . It does feel a little more refined that the 105 with a clutched rear mech i was running so far so good
"6:10 48-31 is the biggest spread of gears Shimano has ever offered in a chainset". My 48-36-26 Shimano crankset just called to say it is not true. On 1/2-by cranks, I guess. Also, a certain Bon Jovi album reference earlier on?
Greatings GCN,awesome channel.That is one super sexy Orbea frameset and equally appealing dedicated Shimano GRX groupset.Thankyou for making me look forward to youtube with your unique,stylish and witty video clips.Cheers
Personally, I'd like lower gearing. I'm a spinner and would like a crank w/ 28/38 chainrings. Flat doesn't happen where I live and the gravel roads climb mountains. Might looking into putting the cranks/front derailleur on my current Ultegra gravel bike.
"The fact that it exists at all is a testament to" ... the fact that Shimano MTB and road components are (for the most part) not compatible, meaning that you can't pair up Shimano STI drop bar shifters with their mountain bike drive chains. It's the single most annoying thing about Shimano products...which are generally terrific.
I've been running Di2 with mountain bike XT derailure and cassette for over a year on my Cervelo S3, no issues, works great. Ultegra crank with Absolute Black oval 50t chainring.
Great American Buffalo Save your $ and go on Amazon and Buy components. I have been running a 1 x 11 for two years 40 chainring and 11x50 cassette. Use top of the line components and didn’t have to pay $$$$. This in my opinion just another way for them to make $$
I can fit them but I couldn't afford... So... YES! Please. I did just order a bike with this groupset and will sell my old one. I hope I can manage to fit a 2x11 setup with a 11-42 gear ring
I think you mostly missed that now there are chain rings that go smaller than a compact crank will accept with it's 110 BCD limitation of 34t. One by for gravel is silly and subcompact makes much more sense to get both the needed range for a low 30 x 34 combo and not too much penalty with 48 x11 top gear for the flats and down. This is the benefit of GRX. One by, you could just go with SRAM, if you don't mind the crappy brakes and Dot whatever brake fluid. Did not know the lever re-design particulars, thanks.
Servo-wave is not the top of the range in mtb. It's available from the lower mid tier, Deore level products. This is a cam pivot design. It's meant to be manipulate the lever ratio. With this shimano can make shorter levers with the same pulling force (and barking performance) as one with longer levers.
2:42 the pivot replacement is only meant for the 800 STI. Lower classes are the same. However there's no "official" 1x RX400, but there's no RX400 crank set and RX600 is available in 1x. So there's nothing stop can stop you to use it as a 1x system.
There have been many reviews and the pricing has been available for some time. On my gravel bike I use road Di2 5p/34 with rear rx and 11/42 cassette (some steep hills here). Can't see that the grx group set really does anything new for us amateurs.
I don't know what I'm doing wrong, but all the off road routes I find in southern England all seem to be comprised of the brown, wet, and gloopy kind of gravel - as opposed to the hard, grey, sunny and pebbly kind that I see in all the promo videos. I've heard the locals refer to this surface as 'mud' in their simple yet endearing vernacular, but nevertheless, I shall get myself to my nearest 'LBS' forthwith (or sooner), and spaff a couple of grand replacing all the perfectly adequate spinny bits of my cross bike with 'gravel specific' wheels and transmission.😋
I have a new gravel bike on order for 2020 with a 2x11 set. I was thinking of making the rear cassette a 11-42 instead of the 11-34 that comes with it but that may require a rear derailleur change which I don’t want to pay for. I’ll wait and see how the current combo works for my long tour that I plan this summer.
I'm looking to build up a Salsa Journeyman for anyroad loaded touring, full GRX setup including sub brake levers, except will run a SLX 7000 24/38 chainset with a 11-34 rear, finished with WTB Byway 700x44 tires ... I hate walking up gravel climbs!
Nice groupset and nice bike also. I'm thinking of buying it. I would like a 44 tooth ring up front and 11 -42 on the back. I have a 42 ring on front of my current bike and could be doing with a slightly harder gear sometimes.
Just installed an FSA Omega 46-30 crankset today. Should give me a more usable big ring for commuting and lower gears for gravel climbs. Not too different from GRX then.
So I take it that GRX 2 x 10 set up can be used with the Tiagra levers if necessary meaning that all that is needed are GRX from and rear shifter? That would be much cheaper yet still enabling a more MTB gear set-up.
I believe that shimano made a mistake by creating the 48x31 front crank with a 17 tooth range. That is too big a gap for smooth shifting. SRAM got it right by using a 13 tooth range on their AXS groupset. When I switched to a 50/34 I did not like the 16 tooth jump and after several years I still don’t. From watching your pro bike videos I’ve noticed that the gap is almost always a 14 tooth spread or less. Thanks for the great videos.
I think it will be popular with older riders & touring riders,maybe even audax riders.i would go for 46/30 on the crank set with a 11/34 rear cassette.
How good would this be on a cross bike? Also should do a 'scientific' side-by-side with a road ultegra on gravel and road routes. That would be a lot of fun to watch too.
I'm not experienced enough to know which sey, 40/42T for front, back or both xD I live in a 'sort of' hilly area and want to keep as much flat speed as possible, but don't want to make the occasional climb on 50-100km+ rides that bit harder, otherwise I would pair the 42T with a 11-40T cassette. especially as it would be my go to bike for deliberate off-road journeys when I give bikepacking a go.
Hey, nice video on the Shimano GRX. I have a question. If you have a GRX810 2x11 set with 31 - 48 chainrings and a 11-34 cassette, is it possible to use the following 2 combos: in Front 48 and behind 34, and also the opposite in Front 31 and behind 11. Also would these „combos“ result in more wear?
Tongue in cheek comment: Oh you mean a SRAM 1x road set. Even the GRX assymetric chainring looks like the SRAM Apex 1x assymetric design. Even similar clutch design. Means SRAM probably did something right last season. Even the chainring seems to copy wide-narrow design features. Thumbs up for the dropper post idea though. Edit: No I'm not a SRAM fanboi, I do prefer shimano - though I admit I have an Apex 1x on my Canyon Inflite Al SLX 6.0, there were no shimano options for the aluminium version.
And i still go for Sram because of e13 9-46 as Long as there is no 12 speed shifter than i go for e13 9-50. I lost a Race because of Shimano, lost my Cain in the downhill Sektion so i lost a minute at 3 Einen Bike Challange
How does the rear derailleur cable pull compare with the road groupsets? i.e. would a RX600 rear mech be interchangeable with a 105 one? So you could do a cheaper upgrade to one with a clutch than getting the Ultegra RX one.

I hope that raised pivot point on levers is adopted by standard road groupsets as well.
It's only Di2 though
@@endianAphones I read that somewhere. Not 100 percent sure.
The chainset and the front mech is different, too.
And upgrading from 105 7000 isn't worth it. The clutch isn't a game change imo.
I've recently read and watched several different descriptions of the GRX line. This one is the best so far. Well done GCN.
Ollie's Orbea is absolutely gorgeous. I love the red to green fade on the fork.
I had to buy this recently. It's stupid but I fell in love with the look and the ride sold me on it. What a great bike.
I really like that brake lever pivot point change. I always found it awkward braking in the hoods on a road bike. I think they should change it there too.
As mentioned as a reply to a similar comment: only the Di2 levers have the higher pivot point.
Was literally thinking the same thing!
My thoughts too, just transitioned from MTB to RB a week ago and braking doesnt feel as natural downhill than when on flats.
The stupidly high amount of setup options available for this groupset are phenomenal. They've really managed to make this line a relevant and marketable product. I could see elements of this appearing on both my out and out race bike as easily as they could be found on my touring mtb. Those Di2 shifters with non linear pull and options for inline hydro are a total game changer.
Doesn't have the setup option I want though - the larger cassette with the double chainring. 😢
I’ve got this group set on my new Reilly. It’s pretty good, the hoods are very comfy and give much better grip. Only issue is the rubberised lever finish, it’s not very robust and scratches really easily, which makes them look tatty pretty quick.

it makes sense though.
-Raised pivot is only in Di2 levers, not mechanical ones
-That rear derailleur is the RX812 for 1x11. The RX810 is the 2x11 option and is really similar to the Ultegra RX800
-The top of the range gravel groupset is the RX810, not RX800, because RX800 is Ultegra RX
-The RX812 RD only can fit a 11-32 or 11-34 cassette as the smallest one (in the biggest cassette 42t easily and even 46t confirmed by me). I use it with 11-34 for cx and with the tension screw almost completely unscrewed to get a proper distance between upper pulley wheel and the 34t sprocket
the cage of RX810 is considerably bigger than one of RX800 (I had both in my hands), but yes, from mechanic perspective they are quite similar
it is super,might also be good for the cobble classics.46-30 is the best gear ratio to chose in combination with grx800.this combination rules
Finally.
Now do GRX vs. Road Equivalent.

In future videos it would interesting to explore how you can upgrade/ simple hacks with GRX components into exisitng groupsets if you are on a budget. For example can you upgrade the chainrings from an existing Tiagra 50/34 to a GRX400 46/30 easily - or do you end up needing to change the FD, RD, chain and BB as well? Then you might as well add in the shifters!! Then up mights as welll upgrade to the 11 speed GRX600 - one of the kids is going to have to drop out of university so I can pay for this!!
Yep, that's a good suggestion - we will add it to the list. Don't want to compromise the kids' education!
I've tried that already and I can tell you that you could do what you asked about if the bracket for the front mech installation allows the mech to move down to accommodate smaller chainrings. In my case I changed from 50-34 to 48-32 and the bracket on my carbon frame did not allow the mech to move down enough for a crisp gear change. Because the bracket was fixed in the frame I had to remove some material from the lower part of my bracket so that the mech would slide to a lower position (about 1mm lower). Wasn't the most elegant solution but that made shifting very good. if you have an alloy frame you could have the bracket installed with a collar which will allow you to move it wherever you feel. Carbon frames tend to come with brackets installed in carbon and moving them is impossible without a major carbon operation which is very dangerous for the frame.
@@L.O.K.I IRD make an adapter for this situation store.interlocracing.com/irddedrad.html
@Timotei of Bollow I did the same and it worked well. I replaced my 105 with Praxis Zayante.
@@vaynomblenner I have tried this little part or a similar one, the problem with the one I tried was that it worked for chain-rings smaller than the ones I wanted to use. The part I've tried was not suitable for such a small difference between rings, 50 to 48. After adding the adapter part the highest position of the mech was too low for a 48 chainring even though I pushed the mech and the adapter at the highest point possible on the bracket.
Well done Dr. Ollie. You are the new official spokesperson for Shimano, they need to send you a huge check!
the GRX looks great! great video!
I know this video 4 yrs old but this is exactly what I need
I've got the new group set on my gravel bike and its very good indeed only had it a week so far so good
at what point would a crankset upgrade to the grx be worth? ive got a pretty cheap entry gravel bike
GCN........Gravel Cycling Network
Seems to be a trend lately
One day of the week, anyways.
Ooookaaaay???!
SPLENDID !🧐👨🎓
Yes
I built a bike around a bombtrack frame and a mix of grx compontents. 600 shifters & 2x crankset, 800 derailleurs and 400 brakes with ultegra rotors. So far I have ridden it for 200kms and the performance is very good! Better shifting than my 105 5800 on my road bike. Brakes are unbelievable as you'd expect from hydraulic brakes.
Some things to note: The 800 series shifters offer a feature where you can adjust the stroke of the brake lever and the different pivot point is only availbale for di2. Dont try to mix 2x on the front with 1x components in the rear. The articulation of the rear derailleur is different and there is not enough tention on the chain. I would try a wolftooth extender for the 2x rear mech to make it for more gears for uses like touring where you need some extra low gears.
good combo in my opinion
damn I bought a Tiagra Cube bike 3 weeks ago. Now the 2020 models got GRX group and they look amazing
I just changed my 105 setting on my Giant Revolt for the GRX600 shifters coupled to GRX400 disk brakes. And now that i will make a 3 day bikepacking across some Algarve mountainous backcountry (its almost like a roller coster), and since I´m on the heavy side, just changed my rear cassete to a 11-40 Slx and just put an extender om my 105 rear mech, and its working fine till now ( crankset is a Praxis Alba 48-32). I really like the Grx shifters feeling.
coming on my new gravel bike next month and can't wait to ride with it!
I had a spin on on Fustle gravel bike with Shimano GRX rx800 group set. The hoods and levers feel lovely and your normal silky smooth gear changes.
Thanks for the video. I was actually very excited about this groupset, since I'm building a gravel bike. But there are some underwhelming points:
0) discs are only hydraulic and I just hate that, because, while it's true offer have better modulation, they are still difficult to set up and if something happens in the field, it's game over. And this all comes at double the price of a mechanical set of very good mechanical discs.
1) The RX800 long rear derailleur, aside from suspiciously looking like a Deore XT piece with GRX written on it and (maybe?) different cable pulls, it's stupidly expensive compared to the XT and SLX homologous, even if you count the cable pull converter. I did not yet see anywhere an RX600 RD, and the big fat RX800 is the only one that can go up to an 11-42 cassette.
I'm a big Shimano fan, but the GRX doesn't do it for me: I went for 105 STIs and FD with an adapted SLX, 11-42 cassette and a double 46-36 chainset at the front. Shimano's mechanical calipers onto Shimano discs. All in exquisite silver☺️.
P.S.: those bits are for sale since a while now... With prices. When did you record this video?
Actually don't be afraid of hydraulic brakes. I've ride them very abusive on mtb- and also on long brevets 400-600km.
They don't fail.
Regarding rear derailleur, I'm using 105 medium and it works fine with 40 cassette. But you can add an adaptor it's 5usd on ali. if it's not enough.
Not sure about the price of Ultegra with clutch derailleur.
Guess the main gain here is the brakes leavers.
Oleg Revulet That's good to hear. I also have them on my MTB but not since long. I must say I didn't really enjoy setting them up with the mineral oil and stuff... And, also, the levers I have don't offer that much adjustment (but I guess this depends on the specific model). One big difference between MTB and road hydraulic discs is the price: hydraulic STIs are still exactly twice the price of mechanical ones. And usually bigger... Yes, I agree that the main point of the GRX may very well be the top levers (still eye-watering expensive compared to their mechanical counterpart).
It's very interesting what you say about the 105 RD, which I guess extends to the Ultegra RX. I went for the SLX because I was after a RD with a clutch and, with the Jtek adapter, came away at around the same price of the Ultegra RX while not requiring an extender, and was still cheaper than the GRX810 --an XT plus adapter would have costed the same but, as you might have already sensed, budget was a very big consideration with this bike.
GRX uses 110 BCD spacing so you're looking at road ring options, not 88-104mm MTB rings. So you'll be limited to 38t or possibly 36t front rings.
@@ohiomoto GRX 2x is 90mm BCD, which is how they can offer 30t
2020 trek dual sport 4 hybrid bikes use the same gearing as your test bike. We threw on some 35c tires from the standard 38c for a bit better on road performance but still keeping that gravel ability. Gravel is here to stay. I'm glad because we have more gravel paths than tarmac paths. Wouldnt mind drop bar option on the dual sport 4 though.
Oh yes, a Shimano dropper Seatpost. That is what the world needed :-D . It is just to much stuff out there and I wish they would just make fit MTB and Roadbike components fit again like many many years ago. Thanks for that review.
The only upsides here over ultegra/105 would be that brake lever leverage thing, but also not completely sure on that, since we already are hydraulic, not cable actuated. 2x with smaller rings and official acceptance of 42t at the back.
Calling it the “worlds first” gravel specific groupset is begging for people to start thinking about SRAM’s 1x offerings and realize that the only way that Shimano can make this claim is by splitting some very thin hairs. They ought to be honest and say “here’s our gravel group, we think it’s pretty good” and not insult our intelligence by making silly marketing claims.
whats srams groupset called?
@@Daniel-dj7fh SRAM Force 1 or Rival 1. Basically 1x versions of Force and Rival with clutch derailleurs.
You can just run the 11sp 1x w a 10sp cassette, no problemo, use a 10sp chain though, wolf tooth has been doing this for years
Ye but why would you?
Save money or fit to existing bike, etc.
I have recently installed a grx fc-rx400 46/30 2x crankset on a bikenstein build that has sora r3000 shifters and front mech. By unwinding the outer limit screw, and properly tensioning the front mech cable, I could get them to work together flawlessly. Shifting is spot on, and I get no derailleur rub. Front trim is somewhat limited though, but it’s nothing unbearable.
Awesome Groupset! As always, from Shimano 💯
Really interesting
A 40 tooth cassette at the front :P
4:50
I heard that and did a double take too!
Sorry 😅
Why have 1 cassette, when you can have 2!
There should be switch for lights also integrated on levers.. Because it's adventurer bike, you need to change light settings from hi beam to low beam or intensity of light, but sometime you can't take hand off from handlebar to do that. In snow or mud or sand or something and then you have no choice but to dazzle all oncoming traffic because you just can't, without stopping at least.. but then it can be challenging to restart once you have stopped on bad road.
Thats a really good idea and something that bike manufacturers will no doubt integrate in the future
Great overview, looks like a great group set confirming Gravel’s confirmed place in cycling. Orbea looks super cool as well.
Pretty cool. But I wish that lowest gear on the1x would go up to say 46 or 50 rather than just 42. I'm really more interested in lower gearing for long steep climbs.
It is sad to see Shimano noticed just in 2019 it is safer to brake reliably. And also the fact I configured 3x9 road casette with MTB crankset to have wider range and tighter stepping than newest/coolest GRX says something whether Shimano really did their homework.
Just got a brand new Trek FX 5 and it has the GRX 600. I have only been out once but it performs very nice.
42/11-32 going on my new Trek crockett. I will be submitting it to the bike vault 🤩
Considering the same setup on my 2020 crockett to replace the Apex it came with. Though on road I wish it were more like a 44 or 46 with a bailout gear in the back. 11-40?
And next year we will see a Gravel specific flat bar and front susp....ooops an MTB
Deal with it!
I’m running SRAM Eagle AXS with a 38t chainring and its pretty amazing on road and gravel...
I just want that new RX400 rear derailleur for my Tiagra equipped gravel bike. The fact that this is already 10 speed compatible makes me so happy to have Tiagra 🙂
It's nice to see Shimano looking out for us bike peasants and not just the performance segment.
been using the 30-46 grx crank for a month or so already both with ultegra 6800 and 105 R700 on different bikes...and it works like a charm. The swap of front derailleur is a nightmare tho. I wish shimano will bring out a 105/ultegra crank with 30-46 for the "big boned" riders :)
keep touching that disk brake rotor and you'll get in gmbn's fail compilation
Rotor*
I understand your concern and in theory the oil from his fingers will reduce the breaking power but from my experience it doesnt really matter so much.
@@SuperDeinVadda correct, but just thought it was funny. You can get the squaling noise because of this.
@@arneseys4729 true true
When ever i get the squealy noises i take a sharp object like chisel and score my rotor with that. The burrs from the scratch are enough to remove the contaminated breaking surface. Pretty ghetto but thats the only method i found working.
@@SuperDeinVadda i burn them with a torch and rub them with sand paper afterwards
As a GRX owner that came on my gravel bike (Whyte Gisburn v2), here's my thoughts...
I like 1x (I have SRAM Eagle 1x12 on my MTB). I love the GRX feel. I love having a dropper post as the left lever paddle. I like the brakes. I like the idea I can add the in-line mini sub-brake levers down the line as an upgrade. So I'd take GRX over SRAM for gravel. With a 38t chainring (it came with Easton cranks and 38t ring) it's fine for off-road stony hills and I wouldn't like much bigger a chainring else if I've got bikepacking luggage, or if I just wanna go up extra steep stuff, I wouldn't be so happy getting up there. But the 11t with the 38t combo can get a little spinny on smooth tarmac or downhill. So I just fitted an XD driver and SRAM 10-42t cassette. That extra 10t makes all the difference. I love it and it now seems perfect for what I want it to do. So I think where Shimano “got it wrong” with their 1x IMHO, is for the best balance it needs a standard 38t chainring available and (I guess with their microspline freehub) a 10-42t. 11-42 is fractionally too slow in the top with a 38t for my liking, but would undermine the climbs with a bigger front ring and the 11-42. Else keep the bigger chainring and have more teeth on the low end of the cassette to give the wider range. Obviously this is personal and depends on terrain and your legs, but for me, using it as a regular commute mostly on tarmac, and adventure bike all over the place in some pretty gnarly off-road places (and the fun bits of the commute), 1x systems with 420% cassette range just plain make more sense than 380% range.
How do you control the dropper post?
@@DrJoel-is3uy With the left GRX brake lever (right brake does all the gears cuz it's 1x)
@@Piplodocus I think it’s only the higher spec grx lever 810 that does it though ?
@@DrJoel-is3uy Yes, mine's 810 (don't know about the other GRX stuff).
Since I'm back here replying to my old comment anyway: yes, I did also buy the in-line sub-brake levers too in the end. Still very happy with it, and still very happy with my swap to a SRAM 10-42t cassette and XD driver freehub instead of of the original Shimano 11-42t (albeit I've already munched through one and on a second the amount I rode it in all conditions).

It’s SHIMANOS first gravel specific groupset. SRAM have had one for years.
I was gonna say the same thing. I've had my SRAM setup for 2 years now. Way to catch up Shimano :)
I'll stick to my 29er xc hardtails.
With 2 sets of wheels, one rigid and one suspension fork
had 2 rides on my gravel bike with GRX mechanical i like it . It does feel a little more refined that the 105 with a clutched rear mech i was running so far so good
"6:10 48-31 is the biggest spread of gears Shimano has ever offered in a chainset". My 48-36-26 Shimano crankset just called to say it is not true. On 1/2-by cranks, I guess.
Also, a certain Bon Jovi album reference earlier on?
I think he meant the 17 tooth jump...
Greatings GCN,awesome channel.That is one super sexy Orbea frameset and equally appealing dedicated Shimano GRX groupset.Thankyou for making me look forward to youtube with your unique,stylish and witty video clips.Cheers
Personally, I'd like lower gearing. I'm a spinner and would like a crank w/ 28/38 chainrings. Flat doesn't happen where I live and the gravel roads climb mountains. Might looking into putting the cranks/front derailleur on my current Ultegra gravel bike.
Thanks for the first ride video and can't wait for my MY 2020 Merida Silex 700 already ordered! (note: with full GRX 810 2x set-up)
Hope they will make 1x road groupsets as well
"The fact that it exists at all is a testament to" ... the fact that Shimano MTB and road components are (for the most part) not compatible, meaning that you can't pair up Shimano STI drop bar shifters with their mountain bike drive chains. It's the single most annoying thing about Shimano products...which are generally terrific.
Not completely true. You can pair Di2 road/gravel shifters with Di2 MTB derailleurs.
@@ohiomoto only the rear deraileurs in a 1x setup though.
I've been running Di2 with mountain bike XT derailure and cassette for over a year on my Cervelo S3, no issues, works great. Ultegra crank with Absolute Black oval 50t chainring.
The ole nine speed stuff works together. The incompatibility bus is probably driven by the marketing team. Sales numbers
seriously cnsidering buying this groupset for my gravel bike... not gonna be the Di2 but stoked AF about it
Great American Buffalo Save your $ and go on Amazon and Buy components. I have been running a 1 x 11 for two years 40 chainring and 11x50 cassette. Use top of the line components and didn’t have to pay $$$$. This in my opinion just another way for them to make $$
Love the new GRX set, only wish is that they made a 9-46 or 10-46 cassette for 1 by use. The 11-46 will do alright but love to have the extra gear.
I can't wait for the 2 by 12 speed do it all groupset for us common types that can't fit N+1 bikes in our shack of a house. Really.
I can fit them but I couldn't afford... So... YES! Please. I did just order a bike with this groupset and will sell my old one. I hope I can manage to fit a 2x11 setup with a 11-42 gear ring
I think you mostly missed that now there are chain rings that go smaller than a compact crank will accept with it's 110 BCD limitation of 34t. One by for gravel is silly and subcompact makes much more sense to get both the needed range for a low 30 x 34 combo and not too much penalty with 48 x11 top gear for the flats and down. This is the benefit of GRX. One by, you could just go with SRAM, if you don't mind the crappy brakes and Dot whatever brake fluid. Did not know the lever re-design particulars, thanks.
OMG, you've already created "Gravel-Cross" now there is the GRX! Almost like you guys saw it coming!
The RX400 is what I'll be putting on a custom made steel frame gravel bike I'll be getting before the year ends, or by January.
Looks like a winner. Time for a new bike day...
Servo-wave is not the top of the range in mtb. It's available from the lower mid tier, Deore level products.
This is a cam pivot design. It's meant to be manipulate the lever ratio. With this shimano can make shorter levers with the same pulling force (and barking performance) as one with longer levers.
2:42 the pivot replacement is only meant for the 800 STI. Lower classes are the same.
However there's no "official" 1x RX400, but there's no RX400 crank set and RX600 is available in 1x. So there's nothing stop can stop you to use it as a 1x system.
for 815 only
There have been many reviews and the pricing has been available for some time. On my gravel bike I use road Di2 5p/34 with rear rx and 11/42 cassette (some steep hills here). Can't see that the grx group set really does anything new for us amateurs.
I don't know what I'm doing wrong, but all the off road routes I find in southern England all seem to be comprised of the brown, wet, and gloopy kind of gravel - as opposed to the hard, grey, sunny and pebbly kind that I see in all the promo videos. I've heard the locals refer to this surface as 'mud' in their simple yet endearing vernacular, but nevertheless, I shall get myself to my nearest 'LBS' forthwith (or sooner), and spaff a couple of grand replacing all the perfectly adequate spinny bits of my cross bike with 'gravel specific' wheels and transmission.😋
I have a new gravel bike on order for 2020 with a 2x11 set. I was thinking of making the rear cassette a 11-42 instead of the 11-34 that comes with it but that may require a rear derailleur change which I don’t want to pay for. I’ll wait and see how the current combo works for my long tour that I plan this summer.
You don't need a new front derailleur. I'm using GRX600 46/30 with a standard 5800 FD, and it works fine.
I'm looking to build up a Salsa Journeyman for anyroad loaded touring, full GRX setup including sub brake levers, except will run a SLX 7000 24/38 chainset with a 11-34 rear, finished with WTB Byway 700x44 tires ... I hate walking up gravel climbs!
I own that bike in metallic graphite with alloy wheels. It's an amazing CX bike.
bike hasnt been released yet matey
Yes it has. I own it. You can see it on my Instagram (fundthmcalculus)
@@scottphillips5677 I stand corrected. I gotta wait until november fml
Just looking at that group set as I'm looking at Ribble Cycles new GRC frame with GRX and 650B wheels ...
Nice groupset and nice bike also. I'm thinking of buying it. I would like a 44 tooth ring up front and 11 -42 on the back. I have a 42 ring on front of my current bike and could be doing with a slightly harder gear sometimes.
Just installed an FSA Omega 46-30 crankset today. Should give me a more usable big ring for commuting and lower gears for gravel climbs. Not too different from GRX then.
04:05 ithe derailleur does feature a clutch, however it's wildly bouncing as it looks... Is that normal?
So I take it that GRX 2 x 10 set up can be used with the Tiagra levers if necessary meaning that all that is needed are GRX from and rear shifter? That would be much cheaper yet still enabling a more MTB gear set-up.
Nice one Ollie! Channeling Grisly Adams getting ready for Winter? ❄️ 🌬 🐻
Very well explained, Ollie!
I believe that shimano made a mistake by creating the 48x31 front crank with a 17 tooth range. That is too big a gap for smooth shifting. SRAM got it right by using a 13 tooth range on their AXS groupset. When I switched to a 50/34 I did not like the 16 tooth jump and after several years I still don’t. From watching your pro bike videos I’ve noticed that the gap is almost always a 14 tooth spread or less. Thanks for the great videos.
I think it will be popular with older riders & touring riders,maybe even audax riders.i would go for 46/30 on the crank set with a 11/34 rear cassette.
And I'd stick with my 3x9 18 year old MTB, because GRX doesn't allow the larger cassette to be used 2X. Such a shame.
I was looking for this information, thanks.
you are talking about a different pivot point, but show ing a 815 electroinc model. A genius😂
shimano should release mechanical brake version for GRX!
How good would this be on a cross bike? Also should do a 'scientific' side-by-side with a road ultegra on gravel and road routes. That would be a lot of fun to watch too.
We're curious which CX pros will be using it this season
I'm not experienced enough to know which sey, 40/42T for front, back or both xD
I live in a 'sort of' hilly area and want to keep as much flat speed as possible, but don't want to make the occasional climb on 50-100km+ rides that bit harder, otherwise I would pair the 42T with a 11-40T cassette. especially as it would be my go to bike for deliberate off-road journeys when I give bikepacking a go.
48-31 paired with 11-30 casette sounds reasonable to me. What about the shifting performance in the front? Isn't the jump too big?
Hey, nice video on the Shimano GRX.
I have a question. If you have a GRX810 2x11 set with 31 - 48 chainrings and a 11-34 cassette, is it possible to use the following 2 combos: in Front 48 and behind 34, and also the opposite in Front 31 and behind 11.
Also would these „combos“ result in more wear?
Tongue in cheek comment: Oh you mean a SRAM 1x road set. Even the GRX assymetric chainring looks like the SRAM Apex 1x assymetric design. Even similar clutch design. Means SRAM probably did something right last season. Even the chainring seems to copy wide-narrow design features.
Thumbs up for the dropper post idea though.
Edit: No I'm not a SRAM fanboi, I do prefer shimano - though I admit I have an Apex 1x on my Canyon Inflite Al SLX 6.0, there were no shimano options for the aluminium version.
And i still go for Sram because of e13 9-46 as Long as there is no 12 speed shifter than i go for e13 9-50. I lost a Race because of Shimano, lost my Cain in the downhill Sektion so i lost a minute at 3 Einen Bike Challange
Cool new gear that makes my current bike obsolete 😒😝
n+1 ;)
Lol. Keep drinking the Kool-aid. It's the same shit.
How does the rear derailleur cable pull compare with the road groupsets?
i.e. would a RX600 rear mech be interchangeable with a 105 one? So you could do a cheaper upgrade to one with a clutch than getting the Ultegra RX one.
Dropper posts are cool indeed 🙃
