  • Dual-soul Gemini shocks

    Meet Gemini, a shock-absorber system with a dual personality. Co-developed with Fox, the Gemini "hustle mode" keeps you high in the saddle with reduced suspension for the climbs to maximize your pedal efficiency, while "flow mode" is low-slung with full suspension travel to let you soar on the downhill.

  • Ai agility

    Asymmetric Integration (AI) is a Cannondale system that improves traction, bike agility and rear-wheel strength, all by asymmetrically positioning the rear hub and drivetrain. Its short chainstays but large tire clearance allow for better control, less effort and exceptional traction and agility.

  • Exact geometry

    The Jekyll 27.5 offers the incredible stability you'd expect, with the add benefit of boosted agility and snap from the ultra-short chainstays of our Ai rear end: 65° head tube angle, Designed for short stems and wide bars for optimum control, Long front-center, Super short chainstays (420 mm), thanks to the Ai offset drivetrain, Steep seat angle facilitates efficient pedaling.

  • Leveraged single-pivot design

    The system's leverage rations can be customized for optimal suspension response throughout the spoke, thanks to an efficient link between the swingarm and the shock. This also keeps the suspension active when you brake, without sacrificing the stiffness, durability, and reliability of a traditional single-pivot design.

  • Point-and-shoot precision

    With Cannondale BallisTec Carbon construction, the stout Ai rear end and LockR pivots holding everything tightly together, the Jekyll 27.5 boasts incredible chassis stiffness for precise control and explosive acceleration.

BallisTec carbon/SmartForm alloy construction

Our BallisTec carbon construction delivers ultra-light frames of exceptional strength and stiffness. The alloy versions use our sophisticated SmartForm aluminum construction – the result of over 30 years of alloy MTB expertise.

Water bottle mount

Keeps hydration at arm's reach and safe from the dirt spray.

Clean cable management

Your cabling as you want it. Interchangeable in-head tube cable guides secure the housing, supporting every possible cable configuration.

Full-on full carbon link

Our full carbon shock link is lighter and stiffer than alloy. Available on all models.

Future proof

Di2 ready. An internal battery mount keeps things clean and clear for internal dropper post compatibility.

Gemini shock absorbers

Co-developed by Cannondale and Fox Shox, the Gemini system adds different ride modes to the Fox Float X and DPS shock absorbers. Hustle mode shortens suspension travel and increases spring rate for a snappier, more responsive feel – perfect for tight turns and challenging climbs. Flow mode brings you back the full travel of Fox suspension for exhilarating downhill mountain biking. 165 mm travel in full mode (Flow). 130 mm travel in short mode (Hustle).

LockR

Our exclusive thru-axle pivot offers a more-secure link between swing arm and the main frame for greater responsiveness and stability as you ride. No twist, flex or special tools required.

Neutral braking

Dialed frame kinematics ensure active suspension, holding the rider in a neutral position when braking for unmatched control.
