What length do you need?
Crank size is an interesting question. Got a road bike, fixed gear, and mtb. They all have a 170mm. Some of the bikes I've looked at spec a 172.5mm crank in my size, others spec a 175! Should the crank length be specd to match the crank on the bike?
Also, can you explain how to pick a chainring offset? Cranksets seem to be more and more complicated then ever before!
