If you don't know the Demo, it's time you get acquainted. Think of it as a two-wheeled, dirt-eating Mario Andretti—it just wants to go fast. And this year, the Demo Expert 29 adds a new limb to the Demo family tree with an entirely new design that makes railing corners and casting flotation spells over rock gardens easier than ever. It has a ground-up new frame, improved kinematics, better suspension under braking, bigger wheels, and all the newest fancy bits that make this the fastest Demo we've ever made. Yeah, we say that every time, but the race clock doesn’t lie. For the Demo Expert spec, we've hit the perfect balance of durability, light weight, and reliability. You're going to find a SRAM GX drivetrain, powerful SRAM Code R 4-piston brakes, a RockShox Super Deluxe RC World Cup rear shock, a BoXXer RC 29 fork, and our Butcher tires with an all-new BLCK DMND casing that rolls fast and is ready for a ton of abuse. - M5 alloy construction works in harmony with our Style-Specific DH Geometry to create the ultimate race machine. The design is compact in order to increase maneuverability and responsiveness, while the 200mm of travel at the rear makes the bike capable of taking big hits in stride. And to fill out all of the details that make the difference on race day, we’ve included an ISCG ‘05 mount for chain guides and all the bits to make it easy to work on. - The RockShox Super Deluxe RC World Cup rear shock features a low-speed compression adjustment, external rebound adjustment, and a Trunnion mount that makes for a smaller shock envelope and increased durability. - RockShox BoXXer RC 29 fork is nothing short of legendary. With 200mm of travel, a DebonAir spring for maximum efficiency, and adjustable low-speed compression, it's easy to see why it's such a fan favorite for gravity fiends.
