The same chassis piloted to riotous success in its very first season on the World Cup circuit, the Demo Race frameset brings 27.5/29-inch rear wheel compatibility to the fore in the search for the optimal balance of speed, traction, and maneuverability while allowing for unmatched versatility. Öhlins's TTX22M.2 coil shock gives you a head start on suspension perfection, just hang your time-tested race kit before you pick up the search where we left off, and there’s a good chance you’ll find a few podiums along the way. The Demo Race M5 alloy frame is fully optimized to take advantage of the traction benefits of a 29-inch front wheel and the increased manueverability of a 27.5-inch rear wheel while maintaining the ability to change your rear wheel size to 29-inch to suit different terrain and riding styles with an adjustable rear end that ensures chainstay length and bottom-bracket height stay dialed no matter the hoop size. The Öhlins TTX22M.2 coil shock is designed to handle the most challenging World Cup Downhill tracks, offering external low-speed compression and rebound adjustment while the Trunnion mount offers extra bushing overlap for increased durability.
