• Rider profile:

    For technically aggressive all-mountain riders / Enduro racers who want to climb fast, but want to descend even faster across the whole range of mountain terrain.
  • Jekyll is:

  • An adept climber and aggressive descender.
  • True two-bikes-in one performance that no other all-mountain bike can match.
  • The perfect enduro machine.
  • TRAVEL
    90mm to 150mm on-the-fly adjustable rear travel. (*some models have 150mm travel X-Fusion P1RL pull shock with platform lockout.)
  • DYAD RT2
    The same two-shocks-in-one DYAD technology found on the other OverMountain bikes, but with shock stroke, air spring volumes and damping created specifically for the Jekyll.
  • ATTITUDE ADJUST
    Switch between modes on the DYAD and the bike’s geometry changes too. Steeper and more nimble in Elevate mode, lower and more stable in Flow mode.
  • BALLISTEC CARBON / SMARTFORMED ALLOY
    Using fibers developed by the military for ballistic armoring, this high-strength carbon construction process yields a frame that’s lighter than aluminum and pound-for-pound stronger than steel. The alloy versions use our ultra sophisticated SmartFormed aluminum construction for a frame that’s light and strong.
  • ECS-TC SYSTEM
    Clamped, 15mm thru-axles in the shock linkage and swingarm pivot, as well as double bearings at the rear dropouts eliminate flex and provide unmatched center-stiffness for complete control.

        Comments about cannondale JEKYLL 4:

        As a former XC racer looking to get into enduro racing, this bike is a major departure from the usual steed. Just standing over the top tube, the bike has an extremely sturdy feel (aided by that 1.5" steerer, no doubt). I was on the fence, and even a bit skeptical about the dyad... Then I rode a demo Jekyll 4. Not only could I still make all the technical climbs, the Jekyll is more than confidence inspiring on the down. It puts me into beast mode. Yes, this comes at a weight penalty, but I feel that it is more than offset by just how fun a bike this thing is to ride! Great stock components for the price point, and you get a frameset that is more that worthy of upgrades. So far I've added a dropper post (a must) and a 740mm bar. This bike has helped reignite my passion for mountain biking, and I look forward to taking it out of the stable every time!

          I believe that cannondale went all out on the JEKYLL 4, the colors are great ( nice and bright ) and the componants are top of the line. I ride every day and have owned many differant bikes , in my opinion this is by far the best looking , best performing bike ive ever had the opertunity to own, and ride. HATS OF TO CANNONDALE GREAT RIDE.
