C1.12 Pinion Gearbox

This is for a gearbox only. You will also need cranks, a DS2 shifter, and a front sprocket (either belt or chain).

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.

The Pinion gearbox is extremely low maintenance and virtually wear-free. Due to the sealed housing design, dirt can’t get into the system. Frequent drivetrain cleaning and lubrication is a thing of the past!

Pinion stands for reliable and durable drivetrains – under all conditions. The magnesium housing of the C-line is treated with a durable, anthracite metallic coloured powder coating. For additional peace of mind, a protective film protects the gearbox from stone chips.

Lighter centre of mass
The compact magnesium housing is 33 % lighter than aluminum. Sophisticated, high-precision manufacturing processes allow the use of an ultra-light “Made in Germany” magnesium alloy.

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
