START SHIFTING FROM SCRATCH

FUTURE SHIFTING

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.
