The N-1 started off as a quest to design the most weather-proof Mountain bikes for Great British weather. OLSEN bicycles have now be designed the N-2 to run a derailleur, however my frames have been designed to primarily to accommodate Gates Carbondrive CDX belts, Pinion gearboxes, Kindernay XIV and the Rohloff Speedhub . At OLSEN HQ we believe in developing bikes around drivetrains and systems that have more long-term benefits for mountain biking than an exposed rear derailleur system. Years of maintenance free cycling. 10000 quiet belt drive miles.
WEATHER-PROOF ENGINEERING FROM THE EU. FRAMES DESIGNED AND MADE IN BRITAIN ..
The derailleur drivetrain was invented in 1928 and works perfectly fine for road bikes where precision shifting is not impaired by mud sand and more mud. A lot of design and engineering has gone into improving the rear derailleur, but this system is still exposed to the elements and mud.
The derailleur has become the mechanical achilles heel when long distances and trail conditions turn bad. We do not want anything to stop you riding…
