I am fairly new to upgrading and doing my own maintenance on my mountain bike. It’s fairly difficult to find quality videos that go into enough depth on the basics. This is the first video of yours I have seen and I am very impressed and thankful. I gave a like and I am now subscribed. Thanks again.
Thats nice to hear, thanks Mark! Let me know if there is anything else I can do.
Thanks for the well explained video. Been off the saddle for a couple years. Need to service my suspension/dropper, and now I'm looking at my gears with disdain after seeing my buddies bike.
Your welcomed. Does he have 12speeds? Are you running a double in front?
@@BikeTeacher yeah, he has a 12 speed and loves it. Almost glad that his previous bike was stolen so that he could upgrade... I just priced the Sram options at 400-600ish. I'm looking at my bike(Santa cruz) right now trying to figure out if my forks and rear shock are toast due to years of neglect. I should probably figure that out first before ordering the drive train. They still compress and rebound, but I've noticed more oil seeping from the top right tube at the wiper seal. My dropper post doesn't rebound correctly at all, I need to physically pull it up while depressing the lever. That wiper seal is visually damaged at the top o ring, but it's an older specialized and I don't see any indication of what model it is... stay safe out there, recent robberies in the oakland hills targeting mountain bikers
@@BikeTeacher woops, forgot to mention I'm running a triple up front. 3x9, too many gears!
Ah, back in the day that was stuff! The conversations easy to 1x11, or 1x12. Just pay close attention to the specs. Your frames drop out width is important. Your current hub may only take a 11 Sp cassette.
Nice tutorial! You might mention you need shorter chain ring bolts since they will be only bolting the one chain ring. You might also mention chain line - it's important you pick the correct side to mount the narrow wide to. Cheers!
Thats right, great advice! I think I have the chain info in another video. The chainring bolt fitting is an issue. Some Raceface rings have the built in spacer but not all.th-cam.com/video/L2Ad5tWERYQ/w-d-xo.html (:
I’m in the planning stage of switching my 11 speed internal gear rear hub to a either a 11 or 12 speed with single chain ring. This is for a foldable bike of 24” wheels so I can’t really use a long cage so I think a 11-42 would suit me. I’ve used this on long tours loaded with 4 panniers but I need better climbing gear than the 11speed Alfine was offering.
So would the long cage come to close to the ground? I assume? I was not aware there was a internal 11 speed hub available. That's cool!
The Shimano M8000 groupset uses a medium cage derailleur for all 1x and 2x (one and two chainring) installations - long cage is only for 3x installations. This group uses an 11 spd cassette [CS-M8000] available in 11-40, 11-42 and 11-46, and derailleur [RD-M8000]. It also only requires a standard Shimano freehub body instead of the new Shimano micro spline freehub (or XD driver freehub in the case of SRAM drivetrains) that 12 spd cassettes require.
I don't want to plunge into an expensive bike yet. So i have a K2 base (2007?)dual suspension that was 3x8 and I converted to 1x8 for now and yes I have that flop issues with my chain. Any ideas what might work
as an upgrade with a clutch?...budget wise ...1x10? Thanks
I was just looking to get a different 1x chainring and was actually looking at raceface, I'm confused though in the chainring description it specifies its for 10, 11 and 12 speeds. I have an 8-speed though and don't get why raceface would say it's supposed to be used for 10 , 11 and 12 speeds. I mean a chain ring is a chain ring right?
The chainrings are specific thicknesses. Most can run two different sizes. * speed cassette have a lot of space in-between gears so the chain can be very wide. As you add gears like today you have 12 gear cassettes. The chain then needs to fit the tight narrow tolerances. So no, chain rings must be different to accommodate the rest of the system.
@@BikeTeacher okay, I ended up going with a Wolf Tooth 1x that said it was for 9, 10 and 11 speed, it seems to be working fine with my 8-speed.
Keep an eye on it. If you have anything funny happen. Could be the chainring is too narrow (thin). Not matching well with the wider 8 speed chain.
Would i be able to run a 9-46 rear cassette with a 46T front chainring on a 1x setup. I am using a shimano slx 11 speed medium cage. Do i have to use a long cage to achieve this goal or do you think i can get away with the shimano medium cage. Thanks for your help.
What if I have a 8 speed shifter and I want to convert to a 1x8 and I have a 11-42T cassette? Will that be possible? If so? What RD should I use with my shifter? Im using a shimano. Thank you so much teacher!
Do you have a 8 speed cassette? 7/8 speeds use the same chain width and shifter indexing. 9, 10, 11, 12 are unique. So you need a rear derailleur, shifter and chain that is compatible with your cassette. You also need a derailleur that has a long enough cage to work with your largest low gear cog.
Keep with a matching shifter and rear derailleur as far as brands go or shifting will be bad. it would be best to have a clutch style rear der. to hold the chain tight to the front chainring. Since you will be missing the front der, the chain will want to come off in bumpy terrain. Unless you have a chain guild in place. I dont know if they make a 8 speed clutch r/d. A narrow wide chainring will help this though.
Great explanation. Now I have a question If I want to upgrade my crank from 76mm 30t to a 96mm 34t do I need a bigger chain?
Not a bigger chain but a longer chain. Either install a new chain and measure appropriately or ad a the needed links to your existing chain. Depends on your current chain wear. Har to say how many more links you will need. I clarify one link as a one narrow and one wide. Some people may call this two links.
I have an ltwoo a7 shifter for my SLX and i run a 1x11 setup, My mechanic limited my rd to only shift to 1 to 9 and removed the ability for me to shift to the 10th and 11th gear because he told me it might break the derraileur, Is it because my shifter isn't Shimano Slx?
Itwoo a7?? Sram? Shifter and rear derailleur should always match brands due to the ratios need to match. A mismatched system will have poor imprecise shifts.
I really found this helpful thanks!
Your welcome Quinn.
The front disc is the same 30 or 32 for 11 or 12 back cassette.? because I want to make it 12 and i don't know if the front it's o.k.?
Either one should be fine. A 32 tooth chainring will be great for a 12 speed cassette.
I am thinking of going to a 1 X drivetrain.
I never really used the higher gears don't feel I need them.
The 1x really simplifies riding. Less clutter, lighten up the load and less fuss inside your head not having to deal with two transmissions (derailleurs).
hello👋! im changing my drivetrajn to 60t how big should my spracket be?
The bike teacher is the dude !!
Thanks!!
Did you need 10mm bolts to install that chainring?
That was a while ago. But I believe the 10mm would work.
hey man, im intrested in making my mountain ish bike (i cant recall what it is exactly) have a 1-10 gear ratio so that i can go faster when pedaling. any idea or information on that sort of idea?
Are you a single speed? Or multi geared? Do you want to just go fast on the flats? Or will you have climbing to?
Bro! I have 1x7 drivetrain with a freaking tourney derailleur, square tapper crankset and freewheel and it just works with NW chainring
Great video helped a lot thanks!
Glad it helped!
When would you replace a chain for your specific drivetrain?
Use a chain checker tool like the Park Tool CC-4 to periodically look for wear. Depends on ow much you ride, the conditions, mud, dust etc. It is best to change it at .75. I equate that to 75% of wear, do not wait till it is 100% worn, you will ruin the cassette.
Can I use my old narrow wide chainring 1x to shimano 12 speed microspine? Is there no incompatibility issue? Can I use 36t chainring on 12 speed 10-51t casette?
Yes, it should not affect performance. As long as its not worn out.
Is that a long cage RD? Would a medium cage RD have enough capacity to accommodate your 11-46 cassette?
It’s possible, check the specs. I don’t know off hand.
Great videos. I am having increasing problems getting parts. Your teaching is fantasic, but if you can't get parts, it gets so frustrating, not in any way your fault. My MTB XC hardtail is based on a Shimano Deore XT M8000. Increasingly Shimano are blocked from buying in another country, even though they are unavailable at home, stuck between a rock and hard place. Is this problem widespread? Does anyone have a really good supplier? Can one get parts direct from Shimano Japan? Likewise with SRAM and Campagnolo from their source countries?
I am not sure about getting them directly from the source, I doubt it. Competitivecycles.com and BackCountry.com in the US seem to be a good resource.
I HAVE A TIAGARA 10 SPEED REAR DIREILLEUR AND 11-46TEETH SUNRACE CASSETTE. I NOTICE THE DIREILLEUR MAKES CONTACT AGAINS LAST 2 CASSETTE SPROKETS IF I PUSH IT IN. DOES THIS REQUIRE SOME TYPE OF EXTENSION ON THE DIREILLEUR HANGER?
Most likely. The cage is probably too short. Research the tiagra and find the maximum tooth count. Wolftooth sells a nice extension.
To use the clutch or not? A have it on a few of my Ebikes!
I like it but yes it can create tooo much tension feel in the thumb lever and make shifter gears clunky. Some Shimano's does have adjustability.
Exactly what I wanted to know. Thanks
Glad it helped
there's galvanized spacers like 5 on drive side on inside of cups of bb
WHAT HAPPENS IF YOU INSTALL A 46T chainring with your 11-46 cassette?
It will be tough to turn on climbs.
I have 10 speed 11-50t is it okay if i will use sram sx crank?
I believe it should be okay. Model and make shouldn’t matter just the fit.
I have a Fuji Nevada 5.0 with 3x7, can I change only the chainring to have it with 1x7 with out getting a derailleur with clutch. The bike has a simple low budget parts. Thank you
If you do it, it will need the clutch and a one x specific chainring. Otherwise the rear derailleur WILL drop the drop the chain.
@@BikeTeacher Thank you
How do you like your Nevada..? Thinking about getting a 2021 Nevada 1.7. just for a little road riding and a little bit of trail riding. Nothing extreme . Thanks
@@Buckeye_4_Life_ I'm 5.6 tall and the bike is a little taller than me, so l recommend ccheck your height first but the bike is solid for the price. I will buy from Amazon and let a bike shop tune it after you assembled
@@casq882 Do you know how much assembly is required when delivered..?
hello what is the correct term in 1x.. Cross chain or Chain line?
I think you may be inquiring about chain line. Cross chain is a term when a double or triple crankset is involved. Like a crooked chain line.
also is there a need for a chain tension device when you have a clutch derailleur
No usually. Unless you are ridding in extremely technical and fast conditions.
Can I put a 40t chainring (1x) to m7100 slx 12 speed drivetrain?
Yes, as long as it is 12 speed compatible. My latest video I built my Surly with a GRX 40 tooth crankset and a GRX rear derailleur. I found out the the XT shifter is not compatible with the rear derailleur even though everything is 11 speed.
So im running on a specialized sirrus x a 46t wolftooth oval chainring and a 11-28 rear ultegra cassette its a 11 speed and im riding with guys running 50-34 and 52-36 if i go up to a 48t or if possible a 50 will i be able to keep up on the flats with this guys or thats not gonna happen
Short answer yes you should have an easier time keeping up with them.Geometry and handlebars may play a part as well.
@@BikeTeacher thank you
so I have a sunrace 9 speed with an 11-40 what chain ring should I use a 30 or 32
It really depends on your legs and lungs. The 30t will be the easiest to pedal up steep climbs.
Great explanation !
Thanks sabrenewf1!!
And if I spent the last 30 years obsessing on gears that might've actually made sense.
said some bs about chainline...this isn't safe to most shops right? more then 3 spacers on bb
Beware too many spacers, as long as there is enough thread or material for the crank arm to secure to.
Guys what is better on your mtb 1 bys or 2 , 3 bys?
I like 1X. One it works well performance wise. Two it lightens the load weight wise. Three, removing the front derailleur is elevating a problem that got people in trouble like any rough shift even on accident could bend it break your chain at minimum.
i change my 32t to 34t and it always make the chain dropped when i go to my lowest and highest gear
Is it a narrow wide tooth chainring? And are you running a clutch style rear derailleur?
can i 1 x with a big chain ring
Is 1x faster than 3x
Faster? Like make you a faster rider? Maybe, mechanically it’s it’s faster overall to use for the rider.
One ring to rule them all... 😂
💍
Want a cassette that will beat sram and shimano gear ratios? Get an Ethirteen 10 speed or 11 speed. Wider percentage than sram and shimano
lol yeah my mechanic botched my bike
can i use my stock chainring?
Yes, but if it is not a 1X chainring it will loose the chain at some point.
@@BikeTeacher okeh
I wanted single speed to my dirt jumper
