Thank you for confirming something which no one else has bothered to explain regarding changing from road cassette to mtb cassette. My gravel bike came without the spacer and I thought the freehub was not to spec. Cheers mate.

Working fine on my Scott Addict to climb north Portugal's 15% gradient hills while saving my knees for when I'm 80. Thank you indeed for showing it was possible and how to do it. [ update after over a year running on it: I seldom use the 34/40 combination now, but it gives me confidence to "go anywhere" even in light backpacking mode. Working flawlessly and still loving it ].
Que combinação estás a usar? 50-34 e 11-40 ? k7 Shimano xt?

@@luiscarloschagasrodrigues6069 Exato: gruupo Shimano 105 com 50-34 à frente, apenas mudando a cassete para XT11-40 atrás. Foi montada com o espaçador pelo mecânico que me vendeu a bike, e até agora tem funcionado muito bem. Na verdade raramente uso o 40, mas é bom saber que está lá se precisar.
Obrigado Vítor... vou fazer a experiência com a corrente que tenho actualmente. Já agora diga-me outra coisa... e possível usar prato grande à frente e grande atrás? E prato pequeno à frente no pequeno atrás? Ou seja cruzado? (Sei que não é recomendado) mas só queria saber se dá para ter todas as combinações possíveis
I can confirm this works. I did it a year ago using Ultegra R8000 and a SRAM NX 11-42 cassette. No spacer was needed fitting an 11 speed MTB cassette on a 10 speed road hub. I inverted the B Screw to get the extra clearance. I did eventually replace the jockey wheels *(from 11s) to a 12 tooth guide and a 14 tooth tensioner to help reduce chain slop.
Done this last night. R7000 groupset 50-34 on the front and 11-40(CSM-7000) on the back. Same chain length (114 I think) and needed a longer b screw for the 40. Shifting a little worse but I could probs spend longer reindexing. Cheers!
Been watching this video. I have an old 1990 Giant MTB. I have ordered a complete 105 R7000 groupset. The wheels are 26" so I ordered some 135mm 11s Novatec MTB hubs to rebuild the wheels. Since the hubs are MTB and and cassette will be Sunrace 11-40T MTB , I am just trying to confirm that the R7000 shifters will still shift fine with this setup. Thanks for the great video! Hoping this setup will be nice and smooth to bring new life to my old Giant Yukon.
@@FreeToCycle thank you for the disappointing news :-) I'm glad you told me as I did not know. trying to upgrade my old giant Yukon has turned out to be very difficult. where I live there are very few steep hills. so I wanted to take this old bike and convert it to a very nice gravel bike and still have good gearing for doing some road riding and for going and doing trail riding. I am in the process of building my road bike and should have it ready in a week or so. That was pretty straightforward on what would fit. I simply ordered the ultegra group set for it and it should work out pretty nice. but taking this mountain bike and converting it has been a challenge to find out what I need to order. if you were going to suggest a good mid-range complete group set that I could put on there to make it very nice, what would you recommend? again thank you very much for your video and especially for answering my questions and help me get going in the right direction
@@FreeToCycle I did find out that the GRX RX810-1 is compatible for a 1x11 setup. So I have asked the seller to see if he can swap out the 105 Crankset for the RX810-1 setup. Not sure if i will wish I did 2x or not. If I went with a 2x I would have to use the GRX derailleur as well. But everything else should work (I think). Feel free to let me know if I missed something.
I just put a 44-28 Samox hollowtech crankset on my Topstone touring bike. With a 12-36 9 speed cassette it works beautifully. Going down to a 26 tooth inner chainring as it will fit. For $14 USA it may be worth a try. That's an 18 tooth chainring gap so it may throw off the ramp and pins function of the outer ring. As a touring bike, big gears are a waste with an upright riding position. Obviously I've lowered the front derailleur matching the large chainring. I'm confident this will fit and at least function with my long cage Sora rd.
Hi thanks for the tip....going from 11 sp. 50/34 - 11/36 with GS drlr. And KOGEL large tooth pulley and want to go to 11/40. Could you please tell me if the same chain will fit, or will it need added links? Thank you.
Hi do you know if you can fit a 12 speed 11/40 cassette to the new Ultegra Di2 group set with a 50/34 front ? It says that the cassette max is 36 but I am curious. I did fit an 11/40 on my 105 with a wolf tooth but was wondering about the new Di2. Thanks
I just installed a Sunrace 11 speed 11-40 cassette on my Rivendell Roadeo. It replaces an 11-36 cassette. I am running a 105 (5800) rear mech with a Sugino 44-32 crankset. I didn't need a "Roadlink". The long "B" screw moved the mech away from the 40t cog enough. Since my chain had less than 100 miles on it, I kept it and amazingly I didn't even have to adjust the length ( well it was only a 4 tooth increase from the previous cassette ). Big/big, small/small will work. Obviously cross chaining but if I do it accidentally at least there won't be any damage done. The key to this setup is the 44 tooth big ring. While this may seem small for a road bike, I can pedal up to 28 to 30 mph without bouncing in the saddle using the 44-11 gear. After that I let gravity and an aero tuck take over. Since I don't race this is perfectly fine. I hit 43 mph this way going down the local big hill. The true test was my first ride with the setup: 44 miles with over 2000 feet of elevation gain. I am supremely happy with the results, keeping a decent cadence on the steepest hills. An additional plus is I have better spacing between the cogs on the new cassette than I did with the previous cassette. I had some 1 tooth jumps on the high end, now the differences are 2 teeth which to me is much more usable.
Saverio [ Sal ] Approvato Hi. Does your Sugino chainring compatible with Shimano 11 speed front shifter? I am currently on 53/36 Ultegra. I read somewhere having too small chainring might cause issue with front shifting
@@mavericktechreview1250 Hi Maverick, I am using an Ultegra 11 speed front derailleur with no problems at all on MY bike. Since the chaining is smaller, the derailleur has to sit lower on the seat tube to maintain about a 1 -2 mm suggested clearance from the outer ring. This MAY cause the rear of the derailleur to contact the chainstay on certain bike frames , especially when shifting to the inner ring. If that happens, you can try moving the derailleur up just enough to clear the stays. The shifting will still probably be good. Good luck.
Thank you for another informative video. Quick question though, your way of sizing makes perfect sense but all other videos I've seen say to use big cog front and back when sizing the chain. My chain is very slack when on small- small and the derailleur runs noisey like you showed in your video. I want to try your method but just want to be sure before I break the chain to take links out. Thank you
Wolf tooth now offers a new Roadlink called RoadLink DM which replaces the B-Link for all Shimano’s new road derailleurs. 105, 8000 and 9000 series. They recommend it for these bigger cassettes. Even though the new derailleur has that B-Link the DM just repositions the derailleur a little better and helps with running things more smoothly. Also if you use Di2, you can now program the Synchro mode so you would never go into the small small or big big combinations.
Dick Tchairdjian I just went through this by installing a 11-40 on my road bike along with replacing the original 105 5800 series with a 105 7000 GS. First I went ahead and used the RoadLink DM with the new 105 but never could get the shifts perfect across the whole range. Ended up removing the RL DM and put the stock Shimano B link back on and it works like a dream. No need for the RL DM.....
@@Brantel. yeah for 11-40T it may not be needed and I know a lot of people are doing that with 11-40T. But I use the 11-42T and just installed the DM on my bike with Di2 and it's working very well. I'm also thinking of buying a 14-28T Ultegra cassette made for Juniors and taking the 14, 15, 16 and 17T cogs from that cassette to replace the 11, 13, 15, and 17T cogs on my 11-42T. First, I can hardly push the 50-11T gears unless I am on a steep downhill so no big loss, but also I found the jumps from 17 to 15 to 13 to 11 too much of a drop... 14, 15, 16, 17 would be a lot smoother. Second, using the new modified 14-42T cassette will help reduce the Capacity of the total set to one that's closer to the Derailleur's actual capacity of 39. [(50-34) + (42-11)]= 47 ------> [(50-34) + (42-14)]= 44. I may even try and remove the Roadlink and also remove another link from the chain.
@Brian Chesteen with your 11-40 cassette and compact crank. Can it shift smoothly into big cassette and big chainring? Thinking about running the same size on my Ultrgra R8050
I was told that having a 16 tooth difference wouldn't work since the capacity is 39 teeth and having the 40t cassette + 46/30 cassette would be past it's capacity for the R8000, you think it wouldn't work?
Do the hubs needs to be changed to accommodate the additional stress/load from 11-40T cassette? And also, how was the performance during steep climbs when changing gears in between?
Well explained. Now i can proceed to what I was thinking alot to just simply replace a cassette with 11-40t.. I got he shimano 105 r7000 36/52t crankset... Also, which size of this cassette spacer did you inserted first hand before putting in the 11-40t cassette?
thank you for your nice and beneficial video ı have a Trek Fx 6 bike with Shimano 105 grup set ( 34/50 crank set and 11-34 cassette ) on it, generally it is ok, but a ı have problem in hills climbing , my question for you will be about possibility of modification in cassette ,or both cassette and crank set? is it possible to change cassette to 40 t or more and crank to 31-48 ,or 28-38 or somethings like this ? ı need your help about this shifter sistem best regards
@ free to cycle ...I watch your videos and I'm mesmerized...and to be honest I need your advise and help ...I have a road bike with dura ace 7900 10 speed (11-28) with short cage ...with crank 50 -34... I live in a hill area and I need a solution....I saw you change the rear cassette to 11 40 with a road link (wolf tooth which I purchased)...the package of the wolf tooth said is working only with medium cage and 11 32 ...2 bike shops I stoped and asked they said is not gonna work ...do you think if I use the short cage with the wolf tooth and the 11 40 cassette,a new chain will work in my case ?
Hi there, I've learnt a lot from your videos so thanks a lot for your work. I've done this conversion with a 'Sunshine' cassette + GRX medium cage and the shifting was pretty awful. How's shifting using a Shimano XT/SLX cassette?
@@FreeToCycle Same exact crankset I’m using here. Assumed you’re using a medium/long cage derailleur, how many chain links did you used for your setup?
I was contemplating the last few days on the XT-M8000 cassette or the SRAM PG1170 11-36. I think the spacer is for 11 speed hubs. 10 speed hubs do need to install the spacer. The XTR M9000 cassette with titanium bits costs double.
I'm on a 34 with an R7000 GS rear mech, I often forget and daydream and find myself in big big gear now and again... Love to go bigger but what would happen if I forgot and went big big with a 40 on??? Does it run in that gear????
I just opted for a 30/46 FSA cranks by 11-36 when I converted my 10 speed road bike...I figure it's now my "extreme hill" bike- I can get up my local Cairngorm on the 11 speed in 34/34 at the steepest parts, but off to do the Bealach Na Ba in summer so want some proper low gears to make sure I don't walk... In these very steep undulating places you don't need stupid high gearing for the descents, 46/11 is fine as this isn't the Alps....the 11-40 ends up with too wide spacings IMHO and with the B-Screw wound in the shifting always goes sub-optimal...
So....3 weeks ago I did Sa Calobra in 50 mins 30 secs (170cm, 85kg, age 55)on a Scott Addict hire bike with 34/50 by 11-34 Di2 12spd....... Yesterday I did the Bealach Na Ba (westbound, the hardest way, 59 mins 11 secs) on my "extreme hill bike" and god it was way tougher despite being roughly same ascent/distance as Sa Calobra. It's a very different profile. Considering now opting to change out this bike to have 30/46 by 11-40 !!! (or lose some weight lol)
Ehou Koto I recently fitted 10 speed 11-32 onto my Cannondale caad 8 road bike with new 105 GS medium cage derailleur, works like a Swiss watch and super smooth shifting with rest of 105 groupset.
@@scampthelazycat9891 Thank you. Actually, when you mesure the distance between the 2 pulleys, the short cage is in fact a medium cage (7.4 cm). But Shimano calls it at short cage (ss version).
I really would have liked to see if the big sprocket / big chainwheel combination would work. I know it's cross chaining but If it didn't work I wouldn't want it on my bike. I may forget I'm in the large ring and in the heat of the climb, looking for lower gears, that's just where I may mistakenly end up. The consequences could rip the derailleur off the bike .
The only way to make that work would be to cut the chain long enough for it. But then there would be slack in the small/small combination. And in fact, there would be slack in several of the smallest cassette sprockets while in the smallest chainring. That derailleur has a chain wrap capacity of 39t, but the difference between the highest and the lowest gear combinations in the final setup shown in this video is 45 teeth, which exceeds the capacity of the derailleur to wrap chain by 6 teeth. So if the chain was cut that long, then while in the smallest chainring he could only shift into cassette gears with 17 or more teeth without slack in the chain. Roadlink or no roadlink, doesn't matter. A hanger extension doesn't change derailleur chain wrap capacity, it only moves the derailleur further away from the cassette to prevent the upper jockey wheel from contacting the larger cassette sprockets.
Hi I run 3x10s on my mtb with 11-36t cassette and I wanna upgrade it with 11-42t and keep my 3x10s. So, will it work with my deore xt m781 RD without roadlink? Thank you.
With my setup, running 48/32 2x front and 11/42 rear, there’s barely enough travel to take up the slack in the chain. Not knowing the spread on the 3x - if it’s more than 16 tooth difference from the largest to the smallest? probably not. The road link will really only help with clearance for largest cog on the cassette, not with the overall take up. Please correct me if I’m wrong 😇
@@clockworkchaos784 my chain srt is 40-30-22T and for me is important to use all cogs on 22 and 30T chain set. When it comes to 40T chain set, I don't need to clear 37 and 42T cogs, I use it only in hihgher gears.
In theory, if you size the chain using the middle ring and granny gear... should work. Just don’t cross chain in the big ring or you’ll have an expensive mess at the back 😜
Yes you can, but you'll likely lose some cross-chaining gear combinations (which is fine as long as you don't forget that and shift into big/big and rip your derailleur off the bike).
Technically it is - road RD's only come in short & medium cages, MTB RD's only come in medium (GS) and long (SGS) cages. At 10sp and above Shimano RD's are not cross compatible so the GS is the "long" road RD.
I believe a 1.85mm spacer is needed.. At least I found this on a bikeshop's page: "1.85 mm spacer for the use of 8- and 9-speed road cassettes as well as 8- to 11-speed MTB cassettes at 11-speed road freehub bodies."
I started with a 116 link chain + master link and still cut 4 links off. Small size frame (400mm from rear axle to crank bolt). Front 52/36 Rear 11-40, Shimano 105 R7000.
I was led to believe that after 9 speeds you couldnt interchange mtb and road without risk of mis shifting. Si thr cassetter work as long as you don't mix derailleurs as the pull ratio is different l. Thats a massive cassette are you planning on loading up for a tour? Did you get it to go up to the 40 in the big ring? I kniw it cross chaining just curious.
Glenny you can go upto the 40 in the large chainring no problem. A friend of mine was curious to know if it would work as he's in his late sixties and goes touring all over europe so it would be useful for him to have fitted.
@@FreeToCycle good to know just in case you had a front derailleur issue. I havent tried the new road derailleurs only got it on my mtb. Inhad a 34 on my 6800 long cage with a dropper worked a treat. I also tried a 5800 with a short cage no dropper with a 32 cass and worked fine. Truth be known i like the 5800 and 5700 feel more than the 6800 . My mate run 11 spd with an old 5700 some say it wont work but ive tested it and it does. I think it put a slim spacer on it like half the thickness.
You are wrong!! The chain on a 11-40 setup will be alot longer than if you were running a 11-25 cassette, the largest sprocket is 15 teeth bigger on a 40 cassette than a 11-25, therefore if you had the same size chain and fitted a 40 cassette on the rear then changed up the cassette you run the risk of snapping the dearilleur off!!
@@FreeToCycle I watched the video again. This is how I size my chain. I.e small/small then take up the minimum slack. At no point does this method see the other cogs. It just happens to fit because it's within limits.
Sorry James got my wires crossed there, yes you can size the chain like you said basically small/small then takeout the slack and it should be fine on all the gears!!

Can the gs 105 handle a 10 speed 11 40?
Do the hubs needs to be changed to accommodate the additional stress/load from 11-40T cassette? And also, how was the performance during steep climbs when changing gears in between?
Hubs 8-10speed all use the same hub. After 10 speed, only MTB Shimano cassettes are compatible using the same hub
Well explained. Now i can proceed to what I was thinking alot to just simply replace a cassette with 11-40t.. I got he shimano 105 r7000 36/52t crankset... Also, which size of this cassette spacer did you inserted first hand before putting in the 11-40t cassette?
Think the 10/11 speed one is usually 1.85mm wide.
thank you for your nice and beneficial video
ı have a Trek Fx 6 bike with Shimano 105 grup set ( 34/50 crank set and 11-34 cassette ) on it, generally it is ok, but a ı have
problem in hills climbing , my question for you will be about possibility of modification in cassette ,or both cassette and crank set? is it possible to change cassette to 40 t or more and crank to 31-48 ,or 28-38 or somethings like this ? ı need your help about this shifter sistem
best regards
@ free to cycle ...I watch your videos and I'm mesmerized...and to be honest I need your advise and help ...I have a road bike with dura ace 7900 10 speed (11-28) with short cage ...with crank 50 -34...
I live in a hill area and I need a solution....I saw you change the rear cassette to 11 40 with a road link (wolf tooth which I purchased)...the package of the wolf tooth said is working only with medium cage and 11 32 ...2 bike shops I stoped and asked they said is not gonna work ...do you think if I use the short cage with the wolf tooth and the 11 40 cassette,a new chain will work in my case ?
Not with the 7900 short cage rear derailleur!
Hi there, I've learnt a lot from your videos so thanks a lot for your work. I've done this conversion with a 'Sunshine' cassette + GRX medium cage and the shifting was pretty awful. How's shifting using a Shimano XT/SLX cassette?
Thank you! Wanted to add some gearing when riding Zwift. Dumb ? What is a “road link?”
Wolftooth road link, basically a derailleur hanger extension!
@@FreeToCycle T U! I later found this item after a google search. Plan to use one after watching your gr8 vid!!!
Useful video. What crankset do you have there?
Shimano 11 speed compact 50/34
@@FreeToCycle Same exact crankset I’m using here. Assumed you’re using a medium/long cage derailleur, how many chain links did you used for your setup?
Will this work with a 52/38 chainring? Many thanks.
I thought MTB cassettes had different index spacing than road shifters can pull?
I was contemplating the last few days on the XT-M8000 cassette or the SRAM PG1170 11-36. I think the spacer is for 11 speed hubs. 10 speed hubs do need to install the spacer. The XTR M9000 cassette with titanium bits costs double.
Can you fit 11-40 cassette on a compact tiagra 2x10 drivetrain with grx rd400?
If its Tiagra 4700 yes the grx rd400 will shift fine, and it will likely clear a 40t cog with b screw adjustment even though it says 36t is its limit.
@@Bikey_McBeardface thanks
How big is the biggest chaining? 40?
I'm on a 34 with an R7000 GS rear mech, I often forget and daydream and find myself in big big gear now and again... Love to go bigger but what would happen if I forgot and went big big with a 40 on??? Does it run in that gear????
It might snap
Will it wprk with 5800 series???
No not without a roadlink!
@@FreeToCycle ok thx
I just opted for a 30/46 FSA cranks by 11-36 when I converted my 10 speed road bike...I figure it's now my "extreme hill" bike- I can get up my local Cairngorm on the 11 speed in 34/34 at the steepest parts, but off to do the Bealach Na Ba in summer so want some proper low gears to make sure I don't walk... In these very steep undulating places you don't need stupid high gearing for the descents, 46/11 is fine as this isn't the Alps....the 11-40 ends up with too wide spacings IMHO and with the B-Screw wound in the shifting always goes sub-optimal...
So....3 weeks ago I did Sa Calobra in 50 mins 30 secs (170cm, 85kg, age 55)on a Scott Addict hire bike with 34/50 by 11-34 Di2 12spd....... Yesterday I did the Bealach Na Ba (westbound, the hardest way, 59 mins 11 secs) on my "extreme hill bike" and god it was way tougher despite being roughly same ascent/distance as Sa Calobra. It's a very different profile. Considering now opting to change out this bike to have 30/46 by 11-40 !!! (or lose some weight lol)
Would a ultegra RX R8000 rear derailleur be ok ot make into a 1x11 with 11-40 cassette?
Yes the rx derailleur will work fine for a 1x11 setup.
Hi very nice. What do you think of an 11-32 or 11-34 with a 105 r7000 short cage? Thanks
Both cassettes will work fine with a short cage r7000 derailleur.
Ehou Koto I recently fitted 10 speed 11-32 onto my Cannondale caad 8 road bike with new 105 GS medium cage derailleur, works like a Swiss watch and super smooth shifting with rest of 105 groupset.
@@scampthelazycat9891 Thank you. Actually, when you mesure the distance between the 2 pulleys, the short cage is in fact a medium cage (7.4 cm). But Shimano calls it at short cage (ss version).
I really would have liked to see if the big sprocket / big chainwheel combination would work. I know it's cross chaining but If it didn't work I wouldn't want it on my bike. I may forget I'm in the large ring and in the heat of the climb, looking for lower gears, that's just where I may mistakenly end up. The consequences could rip the derailleur off the bike .
Big-Big would rip off derailleur. This is the compromise by not using a hanger extension which only costs $10
The only way to make that work would be to cut the chain long enough for it. But then there would be slack in the small/small combination. And in fact, there would be slack in several of the smallest cassette sprockets while in the smallest chainring. That derailleur has a chain wrap capacity of 39t, but the difference between the highest and the lowest gear combinations in the final setup shown in this video is 45 teeth, which exceeds the capacity of the derailleur to wrap chain by 6 teeth. So if the chain was cut that long, then while in the smallest chainring he could only shift into cassette gears with 17 or more teeth without slack in the chain. Roadlink or no roadlink, doesn't matter. A hanger extension doesn't change derailleur chain wrap capacity, it only moves the derailleur further away from the cassette to prevent the upper jockey wheel from contacting the larger cassette sprockets.
@@jimmyzelski7742 what would this affect in the real world?
Hi
I run 3x10s on my mtb with 11-36t cassette and I wanna upgrade it with 11-42t and keep my 3x10s. So, will it work with my deore xt m781 RD without roadlink? Thank you.
With my setup, running 48/32 2x front and 11/42 rear, there’s barely enough travel to take up the slack in the chain. Not knowing the spread on the 3x - if it’s more than 16 tooth difference from the largest to the smallest? probably not.
The road link will really only help with clearance for largest cog on the cassette, not with the overall take up.
Please correct me if I’m wrong 😇
@@clockworkchaos784 my chain srt is 40-30-22T and for me is important to use all cogs on 22 and 30T chain set. When it comes to 40T chain set, I don't need to clear 37 and 42T cogs, I use it only in hihgher gears.
In theory, if you size the chain using the middle ring and granny gear... should work. Just don’t cross chain in the big ring or you’ll have an expensive mess at the back 😜
@@clockworkchaos784 middle ring and granny gear?
What is the cassette you used? Is it a MTB one?
Yes!
if you fit 11-42 can you still use 2x at the front? I run 46/34 on the front.
Im about to do this myself, ill come back and report.
reporting back, it fucking works dude
Yes you can, but you'll likely lose some cross-chaining gear combinations (which is fine as long as you don't forget that and shift into big/big and rip your derailleur off the bike).
Hi just checkin, isn't GS a medium cage?
Technically it is - road RD's only come in short & medium cages, MTB RD's only come in medium (GS) and long (SGS) cages.
At 10sp and above Shimano RD's are not cross compatible so the GS is the "long" road RD.
Anyone have info on the need, or not, for a spacer when installing the 11-40?
I believe a 1.85mm spacer is needed.. At least I found this on a bikeshop's page:
"1.85 mm spacer for the use of 8- and 9-speed road cassettes as well as 8- to 11-speed MTB cassettes at 11-speed road freehub bodies."
Wow, very solid information. How long/many links is your chain now?
i'd like to know, when buying a new chain, you can buy 116 links, or longer ...
I started with a 116 link chain + master link and still cut 4 links off. Small size frame (400mm from rear axle to crank bolt). Front 52/36 Rear 11-40, Shimano 105 R7000.
Great video! What model number is your cassette?
I was led to believe that after 9 speeds you couldnt interchange mtb and road without risk of mis shifting. Si thr cassetter work as long as you don't mix derailleurs as the pull ratio is different l. Thats a massive cassette are you planning on loading up for a tour? Did you get it to go up to the 40 in the big ring? I kniw it cross chaining just curious.
Glenny you can go upto the 40 in the large chainring no problem. A friend of mine was curious to know if it would work as he's in his late sixties and goes touring all over europe so it would be useful for him to have fitted.
@@FreeToCycle good to know just in case you had a front derailleur issue. I havent tried the new road derailleurs only got it on my mtb. Inhad a 34 on my 6800 long cage with a dropper worked a treat. I also tried a 5800 with a short cage no dropper with a 32 cass and worked fine. Truth be known i like the 5800 and 5700 feel more than the 6800 . My mate run 11 spd with an old 5700 some say it wont work but ive tested it and it does. I think it put a slim spacer on it like half the thickness.
Looks like what works for Shimano doesn’t work for sram. I can’t get my apex to work properly. Goatlink doesn’t help
The chain is sized for 11t at the back. In other words same chain size. It could be a an 11-23 no difference. Correct me if im wrong.
You are wrong!! The chain on a 11-40 setup will be alot longer than if you were running a 11-25 cassette, the largest sprocket is 15 teeth bigger on a 40 cassette than a 11-25, therefore if you had the same size chain and fitted a 40 cassette on the rear then changed up the cassette you run the risk of snapping the dearilleur off!!
@@FreeToCycle I watched the video again. This is how I size my chain. I.e small/small then take up the minimum slack. At no point does this method see the other cogs. It just happens to fit because it's within limits.
Sorry James got my wires crossed there, yes you can size the chain like you said basically small/small then takeout the slack and it should be fine on all the gears!!
This is short cage derailleur right? R7000 ss cage?
No GS
😊
Can it fit to 11-46t?
Subscribed! Nice video!
Is that a medium caged mech?
You didn't need a hanger extender to fit the 40 cassette?
How many millimeters is the spacer?
1.85mm
