McPappy Racing introduce their Pinion Tree holder for 36 64 pitch pinions. Designed to last a lifetime the holder is made with the highest quality materials like real 4mm thick carbon fibre to save weight and to protect the teeth of the pinions. The core is machined from a solid block of aluminium and comes in your choice of four different colours with custom colours also being available. The pins are hardened and polished tool steel and the pinion tooth numbers are laser etched into the carbon fibre. The pinions were variably placed to efficiently use the space, allowing to fit 36 gears from 34T through to 70T. The Pinion Tree is available assembled or unassembled, and empty or loaded with CRC 64P pinions.
