With Great British weather it is quite common to run two bikes, one with derailleur for summer and a singlespeed one in the winter. This design started off as a quest to design the most weather-proof Mountain bike for the worlds worst weather. This design can run the humble chain and derailleur or singlespeed, however it is also designed around the most weather-proof drive systems. The Pinion gearbox and Gates CDX Carbon-drive, ensuring quiet belt-drive miles.
This is a rethink on how bikes are manufactured without big brand marketing. A bike is a bike and we should all remember what has been ridden in the past - before marketing. Tour de France was ridden on gravel roads on fixed gears until after WW2. Mountain bikes had a total 1 inch front suspension for XC and DH in the 1990's. John Tomac won both DH and XC on the same bike. This bike will run derailleur, however it has been designed to accommodate the Pinion gearbox and Gates Carbon Drive. This means that you can change your drive system without changing your frame. 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. At Olsen Bicycles, I have designed a frame around the Pinion gearbox based on UK hardtail geometry. With the Pinion gearbox and Gates Carbon-drive belts, this frame has both low maintenance and ride versatility.
