I'm looking to use a compact chainset instead of my current 52/39. Should I use the same crankarm length on the compact as my current chainset (170mm)?
Presume they will have to be same length from the axle to the pedal.
All this starting to look a bit obvious but appreciate your confirmations or otherwise.
Thanks.
