mark ellis Posted June 15, 2010 Share how do you know what crank lengths to ride? looking at ordeing a new groupset and not sure if I should be getting 170 or 175? Link to comment Share on other sites More sharing options...
Pappa Bear Posted June 15, 2010 Share what is your lenght? Go for 170mm if you ride a size small..... or do DH or free riding. 175mm should be fine for a medium / large bike size Link to comment Share on other sites More sharing options...
Barend de Arend Posted June 15, 2010 Share Rule one: if it ain't broke, don't fix it. Your current crank length is stamped on the inside of your crank, next to the pedal hole. Link to comment Share on other sites More sharing options...
patham Posted June 15, 2010 Share I found 175mm was clipping too many rocks when I upgraded to a medium full-sus. Have just swapped to a 170mm set-up and seems to be much better in this regard. But you should have a reason to change size, otherwise stick to what you have. Link to comment Share on other sites More sharing options...
Sharkie 2 Posted June 15, 2010 Share 170mm on small and some medium bikes but generally from medium onwards its 175mm Link to comment Share on other sites More sharing options...
