im running 22:10 right now and its suuuuper sick. if you find that ratio in 38 its awsome. i would say go with a WAAAAAY smaller chainwheel up front. like 28 highest.

i need somthing a bit easirer tho as i strugle on some lines to get enough speed. 22:10 would be a bit hard at the start woulnt it??

no, if anything its too easy. it feels amazing but thats just my opinion.

39-14 atm but it might be 25-14 or 26-14 soon.

EDIT: I dunno if the current one is right because I haven't checked, I just looked on the site. But does 25-14 sound good?
