18 gears and Gates belt drive

Pinion Drive with 18 internal gears and Gates Belt Drive.

I was at Sierra Cycle Works for some biking gear yesterday and I got to ride this cool bike that had an internal 18 speed gearbox integrated into the bottom bracket with a Gates carbon belt drive. It shifts great under a load, has a large range (lower low-higher high) with evenly spaced gears and is maintenance free. You don’t need to lube your chain every ride, or worry about breaking off a rear shifter. This also helps eliminate chain alignment issues with 5 inch tires. This system will be great for the type of riding we use fatbikes for ie: Sand, Snow, loose dirt…. We just need some fatbike frame manufacturers to integrate the Pinion into their frames.
