A whole new sport demands a whole new bike. Built from the ground up to deliver a new level of smooth, fast, and durable performance, the full-carbon-fiber Oso features our first-ever upper-link suspension dw-link platform. It stacks 155mm of rear travel with 170mm up front and is powered by a Bosch Performance line CX motor.
The Oso doesn’t just lean into enduro territory. It drops in, elbows out and goggles down. The long wheelbase, roomy cockpit and slack 64-degree head angle were inspired by our race-winning Ripmo. And its size-specific seat angles allow riders of any height to bang out climbs in comfort without wasting a watt.
Large and extra large Oso frames are built around matching 29-inch wheels, while small and medium frames get the mixed-wheel treatment and shorter chainstays. That keeps the Oso from ever feeling unwieldy. In fact, it’s pretty damn wieldy.
