Pinion Gearbox
C.Line Series

The Future is here


Zerode Taniwha & The Pinion Gearbox

The Taniwha carbon frame is built around the Pinion C.Line gearbox. Seamless shifts, up or down, even if your bike is caked in mud. Your chain will last for years not months because they aren’t tortured into climbing up and down clusters and the gearbox itself is a sealed self contained unit that requires little maintenance.  


3D Printable Bash Plate

For those that ride in rocky environments and feel there is a chance you could damage your gearbox we have developed this 3D printable Bash Plate. The Bash Plate is 3.2mm thick and helps dissipate impacts from rocks or other debris. It fits perfectly onto all Pinion C-Line gearboxes.

The file for the Bash Plate is completely free (the links are downloadable below) you just need access to a 3D printer. We recommend printing in PLA and using a silicone to fix the plate to the gearbox.

If you don’t personally have a 3D printer, a lot of Schools and Libraries do or there are a number of 3D printing businesses around.

Real gears refer to the gear steps of a bicycle transmission that can be optimally used. In derailleur gears, the skewed running of the chain leads to significant losses of efficiency. In addition, when there are two or three front chainrings there will be redundant, i.e. equivalent, gears. A 3×10 derailleur transmission, for example, actually only offers 14 or 15 real gears from this perspective.
