The Zink FR eBike Crankset was developed with freeride rider Cam Zink for the hardest-hitting freeride and downhill e-bike riding. Each arm is CNC-machined from 7075 aluminium in San Diego, California, cut rather than cast for tight tolerances and consistent strength under repeated heavy impacts, and they've been tested at Red Bull Rampage.
The short 150mm length gives more ground clearance to reduce pedal strikes in rocky, technical terrain, a common issue on e-bikes with low bottom brackets. This version fits Bosch motors.
