Cannondale’s Jekyll Carbon 1 has the best kind of split personality disorder. It's a hard-charging, long-travel enduro monster on the descents, and a fast, pedal-happy bike when it's time to transfer to the next high point. Its strong, light Ballistec HI-MOD carbon frame boasts large-diameter tubing, and a revolutionary Fox DYAD shock that allows you to choose between 160mm or 95mm of travel to best suit the demands of the trail and your style of riding. Leading the charge, a stiff, 1.5-inch head tube with a 160mm Cannondale Lefty SuperMax Carbon 2.0 fork pins you on your line. Since you'll probably need to climb to get to the downhill, you have a crisp 11-speed XX1 drivetrain with Cannondale’s super stiff, efficiency-enhancing Hollowgram Si crankset and a beefy BB30 bottom bracket. Other trail-dominating components include SRAM Guide RSC discs, a Reverb Stealth dropper post, and burly, tubeless-ready Mavic Crossmax XL wheels wrapped in fat Mavic tires that absolutely rip, no matter which personality you choose.
