Title: CRANK SIZING?
Post by: HEYWOOD BMX on July 09, 2010, 11:04 AM

 :) I`m currently running 175mm cranks,44/16 and 1.5 tyres.If I run 170mm cranks instead,will it feel much different?

It wont feel much different but your starts may be a bit slower after all you are losing 5mm leverage off each crank arm.   :daumenhoch:

James, it'll gave the same effect as if you very slightly increased your gear ratio. So, in theory you'll have less leverage (worse for starts) but you have less distance to turn the pedals giving you a slightly higher cadence (better for top speed). Overall not likely to change you lap times much (if at all).
