Homegrown Downhill Destroyer


On-One S36 Downhill Bike

Born and bred in Sheffield the S36 has raced at Steel City, flown over the table-tops on DH3 and covered every inch of Wharncouver's trails. It's been tried and tested in the Lakes, pushed hard at Fort Bill and thrashed at bike parks in the northern and southern hemispheres.

The S36 is designed to do one thing and do it fast, and it's the fastest, most downhill capable bike we've ever made. With 8" of progressively damped suspension front and back the S36 is ready to swallow up even the toughest World Cup DH courses. It's stable and predictable at speed yet still agile, enough to feel like an oversized BMX when it's time to start throwing out the tail whips. We built the S36 tough, then we overbuilt it a little more just to be sure. With massive bearings, bushings and huge frame gussets you can rely on the S36 to get to the bottom in one piece.
