Weather-proof EngineerinG. DESIGNED & MADE IN THE UK. FOR THE WORLDS WORST WEATHER.
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.
Gearboxes have more long-term benefits for mountain biking than an exposed rear derailleur system. Years of maintenance free cycling. 10000 quite 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.
OLSEN BICYCLES offers a semi-custom geometry tailored precisely to the customer. OLSEN Carbon frames are monocoque and are all hand laid. Each frame uses a combination of UD Carbon and 3K Kevlar/Carbon weave laid into a tool. I offer advice on geometry options to suit your forks and type of riding that you do.
