Bike crank arm set used on bikes which need 170mm long crank arms.  This set accepts 9/16" pedals and attach to square tapered bottom brackets.

***NOTE***  The most recent batch of left crank arms came in chrome and not black.   Due to the lead time on these, we do not have a lead time on black left crank arms.  

THIS SET WILL COME WITH A BLACK RIGHT AND A CHROME LEFT CRANK ARM.   UPDATED: JUNE 10, 2025
