All-out speed has always been the Demo target, and with the Demo Race it's no different. The frame introduces a new flexible wheel size design that allows riders to take advantage of a 29-inch front wheel and a 27.5-inch rear wheel. This special blend has long been tested by our sponsored riders looking for the perfect balance of traction and maneuverability, but only just green-lighted by the UCI this past year (not that it stopped the Demo Race from racking up both the Downhill World Championship and overall World Cup titles in its very first season). Now, we're offering that same winning combination straight out of the box. Of course, the adjustable rear dropouts allow you to change between 27.5 and 29-inch wheel sizes based on terrain and riding style while also adjusting for proper chainstay length and bottom bracket height. Blazing fast on tough tracks, the Demo Race suspension design has been developed around a more rearward axle path that reduces rear wheel hangup, increasing speed. Top-shelf suspension from RockShox takes advantage of the most proven suspension kinematics on the World Cup circuit and SRAM DH-specific XO1 drivetrain has you covered from the start gate to the finish line. - Not that it needs an introduction, the RockShox BoXXer Ultimate 29 comes from a long lineage of World Cup domination, and its latest guise features RockShox's Charger 2.1 Damper, DH DebonAir spring, and 200-millimeters of podium-bred travel. - 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 maneuverability of a 27.5-inch rear wheel. And, it retains the ability to change your rear wheel size to suit different terrain and riding styles—the adjustable rear end ensures chainstay length and bottom bracket height stay dialed no matter the hoop size. - The Rockshox Super Deluxe Ultimate DH coil shock may be heavy on adjectives, but it's even heavier on performance, offering external low-speed compression and rebound adjustment while the Trunnion mount offers extra bushing overlap for increased durability.
