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.

All of you die-hard alloy fans can rejoice. Yes, the new Stumpjumper ST comes in an alloy version, and it may be the most radically designed alloy bike ever made. And with new tube shapes and an asymmetrical design, the Stumpjumper ST Alloy 29 is sure to exceed your expectations of how a trail bike should ride. Our design goal for the new Stumpjumper was simple—build the ultimate trail bike, one that feels telepathic. And it turns out that this feeling all comes down to stiffness. Think of it this way: when the frame's telling your hands one thing and your feet another, your brain gets confused with the imbalance and the bike feels unstable. In order to fix this, we had to get to work on dialing-in the materials and shapes. We continued down the suspension path with a custom Rx Trail Tune on both the fork and rear shock. Suspension performance is highly dependent on frame, wheel, and rider size, so we use our Rx Tune to get each bike to land in the middle of the adjustment spectrum, and this gives you the biggest possible range to fine-tune your ride. Another focal point of the tune was matching the suspension characteristics between wheel sizes—we developed a specific Rx Tune for each platform. So, no matter what wheel size you prefer, you'll get perfectly linear suspension. Steps were also taken to make this bike easy to live with. Threaded bottom brackets make a triumphant return, and we made room for up to a 3.0" tire. You're also free to run whatever aftermarket rear shock you want since we're using standard metric shocks. And customization is furthered with a Flip Chip that lets you to dial-in your Stumpy to your riding style. Switch it from High to Low and it drops your bottom bracket 6mm and slackens the head tube by half-a-degree. Little details also jump out to surprise you, like a newly designed ribbed chainstay protector that makes chain slap a thing of the past and nearly silences the drivetrain. The build here is no-nonsense with a focus on dependable, high-performing parts, like Shimano SLX front and rear derailleurs, Tektro Gemini disc brakes, a FOX FLOAT Rhythm 34 fork with 130mm of travel, a FOX FLOAT DPS Performance rear shock with 120mm of travel, and wide alloy wheels. - The all-new alloy Stumpjumper ST frame features an M5 alloy front- and rear-end, an asymmetrical design, and our 29 Trail Geometry, so it's both capable and comfortable. - The FOX DPS Performance rear shock features our Rx Trail Tune, ensuring that no matter the frame or wheel size, your bike is dialed-in perfectly. - A FOX 34 Rhythm fork handles suspension duties up front with stiff stanchions and plenty of adjustability.
