C-Line Pinion gearbox

DESIGN OF THE GEARBOX TYPES

Common to all gearboxes is the spur gearing consisting of two sub-units connected in sequence. The individual gear ratios are derived by matching the two sub-units with various cog pairings.

The C1.12 gearbox is built using a 4-gear unit mated to a 3-gear unit – a 4 x 3 gearing type. The C1.9 is a 3 x 3 type.

C1.9

E-bike and enduro riders love the pure efficiency of the 9-speed gearbox. The C1.9 is optimized for applications where larger gear steps and efficient shifting are a priority.

C1.12

The C1.12 gearbox is the shifting system for everyday, leisure and touring riders. 12 finely stepped gears offer an outstanding gear ratio range and unique shifting comfort. With a 600 % overall gear range, the C1.12 gearbox easily outclasses modern derailleur drivetrains.

C1.6

The C1.6 is our lightest gearbox type and is used in urban e-bikes, E-cargo bikes and commercial fleet and rental operations.
