the PINION GEARBOX frame bike builder
The N-1 will not run derailleur, it has been designed to accommodate the Pinion gearbox only and Gates Carbon Drive. Gearboxes have more long-term benefits for mountain biking than an exposed rear derailleur system. Years of maintenance free cycling. 10000 quiet belt drive miles.
The N-1 is designed around the Pinion gearbox and 2 tyre sizes. Both 29 x 2.4" and 27.5 x 3.0" (plus sized) tyres without affecting the handling. This design uses the benefits of carbon monocoque construction from one huge tool. However the "reach" (top tube) can be changed from between 420 - 485mm by using tool sections to lengthen the frame. Fully custom options are available, allowing the head angle can be anything from 65 to 70 degrees. Bottom bracket drop can also be custom made by changing the mounting plates.
