The Pinion gearbox is an internal gearing system for your bicycle, which eliminates the need for the front and rear derailleurs you are used to seeing on so many traditional bicycles.
The Pinion gearbox is basically a small metal box that is built into the bottom bracket of a bicycle… and inside that metal box is all of the gearing for your bike.
Because the gears are internal, like the gearing on a vehicle engine, the Pinion gearbox requires no regular cleaning or maintenance – other than simply wiping down the outside of the box whenever these parts becomes dirty.
The Pinion gearbox itself, like the engine in your car, however, does require a regular oil change – approximately once per year.
If you watch the video above you will learn how to perform this quick and easy Pinion gearbox oil change for yourself. All you need are a few basic tools, a catch basin (or a plastic bowl/cup), a towel or rag to wipe down any excess oil, and some replacement gearbox oil, which can be purchased directly from Pinion or from the Co-Motion Cycles website.
While there are different size Pinion gearboxes available, the oil change process is pretty much the same on all of the gearbox models.
