Schlumpf Mountain Drive Internal Gearbox makes you gain a very low additional gear upfront, which enables you to climb even the most extreme inclines easily.

The extremely flat planetary gearbox shrinks the gear ratio by a huge factor of 250%. Shifting while standing still or under heavy load on a mountain road is not a problem; a simple kick with your heel and the fun can start.

Push on the right crank-arm to shift down, push on the left one to shift back into direct drive. No cables, no shifters.

Symmetrical clutch allows full torque in both directions, both forward and back-pedalling, making it compatible with coaster brakes and fixed gear bikes without a rear brake.

Optional Easy-Shift plates cover the whole arm, making in possible to shift by pushing on a larger area, best for clip-less pedals.
