Crank Size? | Mountain Bike Opinions Discussion board

An more and more frequent college of thought is “run shorter cranks for much less pedal strikes on these bikes with tremendous low BB’s”.

The physics and science behind it’s fairly easy although. Longer cranks provide you with extra leverage, however that is one thing you’ll be able to regulate for with gearing if wanted (going to a smaller chainring if wanted). So far as biomechanically, there have been some research on this. And mainly they discovered that the folks within the research put out the identical quantity of energy on an enormous vary of crank lengths (from like 140mm as much as like 200mm).

Which suggests, to me, run no matter crank size you need :)


Some advocates for brief cranks additionally report much less knee and hip ache (your joints are rotating much less), and a extra even stance on the bike when going downhill (your toes are nearer collectively). Potential downsides are your seat top shall be greater.

Personally I went from 175mm cranks on my final bike, to 165mm cranks on my new body up construct. I see no draw back, and truthfully not one of the buddies I’ve let check trip the bike have seen the crank size.
