The Cannondale Men's Jekyll 1 29 Mountain Bike is a hell of a climber but this bike grips, floats, and pedals like nothing else. The Jekyll 1 is perfect for enduro racing, bike park sessions, high-speed mobbing, and thrives on steep, fast, rowdy mountains. The shock tucks cleanly into the twin spar downtube, keeping the bikes center of gravity as low as possible, giving you wicked stability, instant line changes and one-of-a-kind looks. With the proportional response design, everything fromthe suspension layout to the geometry, even the length of the chainstays is customized by size, forperformance built just for you. This Cannondale bike has suspension like no other with its Fox FloatFactory shocks and a high main pivot that gives this bike a bump-swallowing rearward axle path forsmooth landings and stability whether you're riding on roots or rock gardens. You'll be impressed with features such as the revolutionary Guidler, a combination of the idler pulley and chainguard, this new technology kills the pedal kickback of high pivot systems and of course keeps your chain on. The Ai Offset Drivetrain delivers more tire and mud clearance in the swingarm, and more even spoke angles for a stiffer, stronger rear wheel. The 4-bar linkage keeps your braking smooth, traction highand pedaling crisp. Lastly, the downtube protector keeps your frame safe from roost and strikes, while letting water and debris pass through. Descend into greatness with the Cannondale Men's Jekyll 129 Mountain Bike.
