Crankset Spindle
Zink FR E-Bike Crank Arms hold up at 150mm on rough terrain
The Zink FR E-Bike Crank Arms are CNC-machined from 7075 aluminum in San Diego, California, cut rather than cast for tighter tolerances and consistent strength under repeated load. Built at 150mm, they're compatible with Bosch, TQ, and Avinox motor systems, with a dedicated version for the Gen 4 Levo drive unit to match its specific interface. The shorter length trades nothing in stiffness, it's a deliberate choice for ground clearance on technical, obstacle-heavy terrain.
What Our Gearhead® Experts Are Saying:
"I measured deflection against a stock crank at the same length, and these held tighter under load through a full ride. Machined 7075 aluminum reads different than cast the moment you put real force through it."
