This precision instrument is for the enduro artists the ones who will use all 150mm of its Fox Float performance travel and poppy quickness to dance and float through the chop and chunder on their way to the top step. Unlock your potential of this punchy ripper purpose-built for hunting enduro podiums.

Co-developed with RockShox the killer performance fork and rear shocks outperform the competition on all terrain. Easily adjust the dampening for the customized responsive feel you want either for pumping through turns sprints and traction-challenged climbs. Or for full travel when things get rough. Asymmetric Integration (Ai) delivers some of the shortest stays on the trail yet has more tyre clearance and frame stiffness than even Boost frames can muster. For this 2020 model Cannondale have kitted the Jekyll out with bigger more capable 29” wheels for improved rolling ability and speed. Plus a rear wheel that’s stiffer and stronger thanks to the Ai even-dish build. It all adds up to the kind of agility and traction that must be ridden to be believed. The Jeckyll Delivers all the slack stability you’d expect from a top enduro rig but with uncanny agility and snap thanks to the ultra-short chainstays of its Ai rear end. Placing a link between the swingarm and the shock has allowed Cannondale’s engineers to customise the system’s leverage ratios for optimal suspension response throughout the stroke and keep the suspension active under braking while retaining the stiffness durability and reliability of a single pivot design. With its SmartForm alloy construction the stout Ai rear end and LockR pivots holding everything tightly together the Jekyll has incredible chassis stiffness for precise control and explosive acceleration.
