    crank help please

    Hi everyone!

    Posted this one on drivetrain forum too.

    2014 Enduro 29er has a stock SRAM S1250 2x10 22/33 crank.

    I really like the 22 chainring, because it's much more easy for me on the climbs! also, I want to keep the AM setup of the bike.

    question No.1
    Should I go for 22/36 x9 crank, so I'll keep the 22 chainring and still have the 36 chainring for more speed? Will upgrading from 22/33 to 22/36 be noticeable, or should I just stay with the original 22/36 ?

    question No.2
    Should I go further and get the 24/38 x9 crank, or maybe the 24 chainring would be a big difference and make my climbing harder? Think this setup might not be my preffered AM setup, or maybe I'm about it?

    what would you do?

    Thanks, Mo.

    I run a 22/36 currently and use to run a 22/34. The 34t was not big enough for the faster trails I ride and I would regularly run out of gear, the 36t really helps and puts the bike into a better gear to give you more power down at almost any speed.

    I would only go to a 38t if you're riding trails where your average speed is over 30mph, anything less, which is basically all all-mountain trails. So stay away from the 38t. I would go with the 36t, better gear spread with the 10 speed cassette.

    38t is way too big for anything but the road, the amount of times it's useful on the trail are so few and far between that new bikes do not come with rings that big anymore. Even many DH bikes don't have rings that big anymore.

    The crankset that came on your bike isn't a bad crankset. A better, and much cheaper suggestion would be for you to simply just buy a larger chainring and swap it on in place of the 33t, especially since you said you liked the 22t smaller ring. If you want more speed out of your setup, swap on a 36t and call it a day.

    Thank you all! you helped me.

    Owensjs - as I wrote, the E29er has a 22/33 while the SJ has 22/36.
    Gonna pull the trigger for the E29er, so my LBS said he can replace the 22/33 with a 22/36 for free, so I don't have to buy a larger chainring and save some $$$ for X9 shifters and SLX brakes (I want the XT's but I'm on low budget and heard some good things about SLX)
