Making the most advanced bicycle gearboxes in the world, Pinion makes high-precision shifting systems modeled after proven automobile transmission technology. Centrally integrated into the bicycle frame, Pinion gearboxes offer unique cycling dynamics and unparalleled shifting performance. Pinion gearboxes are ideally suited to the rigors of cycling. Virtually wear-free and requiring no adjustments, the gearbox provides long-term reliability under even the most demanding conditions.

Pinion gearboxes shift at lightning speed. One or multiple gears, whether stationary or while riding!
We use a rotary-style shifter for optimal gearbox control.

Pinion gearboxes are ideally suited to challenging conditions that would quickly destroy other drivetrain designs. The sealed gearbox is always ready for action: sand, mud, rain, and snow don’t stand a chance. Even narrow and technical trails pose no threat thanks to the internal shifting mechanism.

Pinion gearboxes are fully sealed from water, mud, and snow


The C-Line gearboxes are available with 12, 9, or 6 gears. Patented shifting technology in a compact housing made of lightweight magnesium.
