FSA SL-K Light BB30 Tandem Rear Left 170mm Carbon Crankarm Crank Arm CK-OS8681
Tandem Left Arm. This crank arm uses a left threaded pedal. Move as many parts as possible without it being a pain. Just keeping it real. Pulling that off is a bit easier said than done. If a dispute arises, if we are at fault, admit it early.
