I'm looking to part with a crankset I recently acquired. The cranks were intended for a single speed build; however, after losing out on two frames on two separate occasions I've ultimately lost interest. The crank arms measure 175mm, and the teeth have tons of life left. The crankset works with a standard extrnal bb (I have ran the same crankset before with a XC Raceface bb without any issues). If you have any questions feel free to ask. Thanks for looking.
