The evolution of the worlds most successful Enduro platform! Working with Enduro World Champion Jerome Clementz, Cannondale made his winning bike even winning-er with all-new geometry, a new Fox DYAD rear shock tune with increased travel, and of course, 27.5 wheels. You don't have to be Jerome to appreciate its perfect-for -Enduro dual nature - you just have to want the most versatile all-mountain bike out there. With suspension travel, which can be adapted during the ride from 95 mm to 16 mm, and a geometry that can transformed instantly from an agile trail bike to a stable downhill bullet it's perfect for all Enduro racers, or all-mountain shredders who want to climb fast, but want to descend even faster across the whole range of mountain terrain. Lurking inside the new Fox DYAD RT2 are two different shocks - one short travel (Elevate) and one long travel (Flow) - which are activated by a handlebar switch. The 215 Dyad gets a redesigned Flow mode piston engineered to complement changes Cannondale have made to the SuperMax PBR Trail Damper. The new piston enables better oil flow for improved mid-to-high speed compression damping performance. This results in smoother, more supple mid to high speed performance. Like the SuperMax, these changes will be especially noticeable on small, sharp bumps, square edge hits and chatter/washboard bumps at speed. Sag optimized at 3% instead of 4% resulting in more usable/positive travel and increased ride height for better pedal clearance. Significantly wider range of rebound damping adjustment, thanks to increased oil flow. ELEVATE: In this mode, the shock behaves like a short travel, XC-ish air shock. The Flow chamber is completely closed off and only the Elevate side of the shock is active. All oil is routed solely through Elevate damping circuits. Damping and Shock response is optimized for climbing and rolling terrain. Performance not compromised. High-speed, long travel damping is handling by separate circuit. Air spring volume is reduced / Spring rate gets very steep and progressive. This reduces travel for a snappy, efficient pedaling feel. Controls unwanted suspension movement via spring rate, rather than with extra compression damping like traditional shocks. This allows free and fluid movement through the first part of the stroke, for smoother, faster rolling and improved traction. FLOW: In this mode, the shock behaves like a coil-spring DH shock. The Elevate and Flow air chambers are connected creating a large volume air spring and all oil is routed solely through FLOW damping circuits. Air spring volume is dramatically increased / Spring rate gets very linear and coil-spring-like. This increases travel for a fluid, supple feel and bigger hit capability. The linear-to-progressive spring rate gives a predictable, controlled feel, and prevents bottoming. All oil is routed solely through Flow damping circuits. Since damping duties for other types of terrain are handled by the Elevate circuits, the Flow circuits are optimized specifically around the needs of high speed, aggressive descending. With the Pike RCT3 RockShox contributes a light and excellently performing fork with stiff 35 mm stanchions for the Jekyll to conquer all the challenges in tough All Mountain or Enduro races. The combination of the super-light Solo Air spring with the comfortable Charger damper with RCT3, anodized stanchions and the new casting makes the Pike a stiff fork with perfect damping. The integrated bolt on cable stop allows for neat routing of the brake hose. The spring rate of the light and plush Solo Air spring can be adjusted using just one valve, effectively filling the positive and negative air chamber simultaneously. Cannondale Jekyll Alloy is a pure expression of aluminium artistry! It is made of 661 aluminium alloy and heat-treated to a T6 hardness for strength and durability. The shape optimized tubing helps reducing weight and increasing strength. The trademark double-pass smooth weld technology eliminates the stress-risers and weak points found on traditionally welded frames. The X-12 thru axle and dropout system provides the stiffness of a 12 mm thru axle with the quick wheel changes and ease of use of a quick-release wheel. The ECS-TC SYSTEM stands for a clamped, 15 mm thru-axles in the shock linkage and swingarm pivot, as well as double bearings at the rear dropouts. That eliminates flex and provides unmatched center-stiffness for complete control. In addition, the frame comes with modern BB3 bottom bracket standard. The Jekyll Alloy is equipped with a Shimano drivetrain and RaceFace crank for smooth shifting performance with 2x1 gears. Hydraulic Shimano SLX disc brakes allow great braking power. The wide handlebar provides maximum performance and the rock solid but still light, UST tubeless wheelset with WTB Frequency Race i25 rims forgives even muffed hard landing. Also contributing to the enormous versatility is the Trans-X adjustable seatpost. It saves the seat adjustment before and after downhill sections.
