you running a ffw or freehub? square taper or isis?
I need something that will be good for high speed things but good enough for more skippy, technical, static stuff.
thats more gearing than crank arm, but shorter cranks make the gear feel harder but you can get a better sprint out of them. longer cranks give more leverage, making the gear feel softer and giving more power. as for actual cranks, try-all ones are expensive but light and incrediably strong. DO NOT get the echo forged cranks there around £50 and the threads die really fast if you run a freehub, get middleburns if you can afford there freakin' awesome i'm running meta cranks right now and i'm really impressed with them lots of nifty features to save the threads and they feel really stiff and can take a beating
