crank length?(2 posts)

I'm planning to get a new crankset, and I've been leaning toward going with something a bit longer. I have 170 mm on my road bike, and 170 on my 'cross bike right now. Would I notice much improvement by going up to 172.5? Problems? I'd like a bit more of a push going up sharp hills.

[My inseam, by the way, is 77.5 cm, and I have shortish calves...]

I ride 172.5 on the road, and 175 on my 'cross bike. Short, sharp hills are one thing, but the place the longer cranks will give you the most bang is slogging through grass or sand (or for that matter, most of a cyclocross course) at lower RPMs.
