This bike's attitude can change, so when the trail points up, you won't have to change yours. Cannondale's Jekyll 3 dominates up and down with a revolutionary Fox DYAD rear shock that allows you to choose between 90mm or 150mm of travel while also adjusting the geometry to best suit the demands of the trail and your style of riding. Its strong aluminum frame boasts large-diameter tubing for efficient power transfer and has a 1.5-inch head tube that keeps the 150mm Fox fork on your chosen line. Other trail-dominating components include 2x10 gearing, Magura brakes and tubeless-ready Shimano wheels that use a 15mm front axle and a 142x12mm rear axle for stiffness. So if you're into aggressive, all-mountain riding, or simply want to be better at it, the Jekyll is your kind of monster.
