18 real gears with even steps of 11.5%.
Overall Gear Ratio 636%. More than any derailleur system or hub gear.
Lightning-fast shifting of any number of gears in any situation.
Ride hard without worries. A sealed rugged housing protects the gearbox from dirt and damage.
Extremely low maintenance. The transmission operates in an oil bath (using biodegradable oil) and is designed for a mileage of at least 60,000 km.
Optimal weight distribution. A low centre of gravity and a light rear wheel improves handling, suspension and dynamics.

START SHIFTING FROM SCRATCH
With the Pinion rotary shifter both individual and multiple gear shifts can be made with split-
second precision. The indexing of the shifting is at the gearbox so unaffected by stretched cables or damaged cable housings. The shifter is designed so that its contours are comfortable to hold so allowing bar and shifter to be safely covered at the same time with no risk of accidental shifts.
The soft rubber coating and the raised ridges make the shifter secure and easy to use even when wet. The shifter gives direct feedback when switching gears: the load on the chain and the force needed to shift directly relate to each other. You can sense immediately at the shifter the moment to shift gear so you learn fast shifting with a new Pinion gearbox in no time.
