    New Tallboy drivetrain question

    The small gear on my Tallboy is a 26 tooth. I need a smaller sprocket. The hills here in Cali are STEEP...What is the smallest sprocket I can use?

    What rear cassette are you running? I also live in So Cal and a 26 is good for me. Where do you ride?

    It's an XT cassette. 36 is the biggest. I am in the Bay Area ca. I ride a lot at Henry Coe. On my Enduro I have a 22 front 36 rear. But that's also a 26" wheel bike

    I had a 22T (Sram) that was good for the really steep stuff but would spin out on the flats. Sorry I don't know the Shimano stuff but I would guess there is an aftermarket 24T ring.

    Edit...just google 24t Shimano and there are several options

    Here is So. Cal., everything is steep......ran a 32x11-34 9 spd for 6 months. Just recently went 10 spd....32x11-36.

    Ride more.

    Think you just gotta get stronger.
    I crashed hard enough on my Tallboy to break my leg,
    The carbon is way more durable than most people.

    I've used a 22 (race face) on my XT 3x10. Currently using a 24 (shimano).

    If I ran a 2X10, I would probably use a 22 or 24 paired with a 36 large chain ring.

    I like how you ask a simple question and then get lectured about "getting stronger", not!. No need to justify IMO, XT small ring is 64 bcd and there seem to be plenty of 22t rings available in that size.

    I was worried if I went too small I would have trouble up shifting in front. I ended up going with a 24. I am guessing because it is a 29er that they run higher gearing? My stock 2x10 on my 26" enduro was a 24/36 crank. This bike is a 26/38 crank

    You can get a 22 granny but you may exceed the capacity of your front derailleur. You need to check the model of front derailleur and your large front chainring size.

    Just give it a try. If it has trouble shifting from 22 to 38, replace the 38 with a 36 or 34.

    vinny, I'm also in the Bay Area on a Tallboy Lt. It came standard with the 26x38 front rings, but I swapped to a 24x38 combo. Much better for me, but if you are using your 22 front x 36 rear combo on a lot your 26er, you will almost certainly need to swap out to a 22 small ring in the front for your Tallboy. However, if you go a 22 small ring, I think you ought to change the large ring to a 36 (biggest) to have reasonable shifting performance. If you ride Henry Coe a lot, I think a 22x36 would be a good set-up.

    Would I have to adjusted the postion of the front derailer down?

    I would think so but will let someone who is more mechanically inclined answer. Or you can just ask the shop where you bought the bike.

    I did similar to GMM on Turner 5 Spot. Switched from 26/38 to 26/34. Best upgrade for me. Now I am about to switch to 24/34 to make front derailleur happier. I use 11-36 cassette. I used Blackspire Super Pro 10434 chainring (104 BCD 34 tooth =10434 if new to this stuff), and sold used Shimano 38 to almost pay for swap! NORCAL steeps. 22 tooth seems like the right move for a 29er.

    New Tallboy drivetrain question

    Shimano goofed with the 26/38 2x10 crankset - too big for most 29er riders with any good hills.

    Should have maybe had more than one option? 26/38 seems about right for 26" wheeled bikes...........oh wait do they still make those? ;-)
