"Ti Fixed" Titanium 1/2-Fixed-Gears Carbon-Belt-Drive
Less weight, no derailleurs = MORE FUN!
Chain or Carbon Belt Drive
Front Calliper Brake
Single-Speed or Schlumpf 2-Speed Internal Gearbox with Foot-Button Shifter
Schlumpf 2-Speed Internal Gearbox can either add a more conventional second gear or a much shorter extra climbing gear. The extremely flat planetary gearbox shrinks the gear ratio by a huge factor of 2.5. 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 brake and fixed-gear bikes without a rear brake.
