The all-new Cannondale Jekyll is a trail and enduro machine that the top-tier brand launched today. It’s an all 29er package with 165mm rear & 170mm front suspension. Four sizes are available and they cover reach numbers from 425 to 510mm. The shredder has a 64° head angle with a whole bunch of special tech from one of the best innovators in the business. It is a completely redesigned bike featuring a Gravity Cavity, High Pivot, Guidler, Four Bar linkage and the brand’s very own Proportional Response Design. Let’s take a closer look at all that special sauce.
The Gravity Cavity
The Gravity Cavity allows Cannondale to put the shock inside the downtube which enables the lowest possible center of gravity for the bike. This lower C-of-G makes the bike more nimble on the trail, more stable at speed and more planted in the turns.
The High Pivot
On the new Jekyll, the swingarm pivot is located high up on the seattube which means the rear wheel moves backward and up when hitting a bump. This rearward wheel path helps the bike roll faster and carry momentum on rough trails.
The Guidler is one-part chain guide and one-part idler pulley positioned to eliminate chain growth as the suspension compresses. This, in turn, eliminates nasty pedal kickback from the gnar-eating high pivot layout.
Four Bar Linkage
The Four Bar (aka: Horst Link system) allows the engineers to control two important variables called rise (when you hit the brakes and the back end lifts) and squat (the tendency for rear suspension to compress under acceleration). Correctly tuning the anti-rise and anti-squat means the bike is more efficient as it doesn’t rise too much when braking and squat too much when pedaling.
Proportional Response Design
A riders center of gravity influences how the suspension behaves. Now, taller riders will naturally have a different center of gravity than shorter riders. Cannondale’s Proportional Response Design simply means that the geometry and suspension kinematic, on each frame size, is tweaked to optimize the center of gravity for the average height of a rider on that particular frame size. In short, its a customized suspension layup.
Across all the size curves it is naturally low, long and slack but its the size-specific geometry that tweaks the suspension kinematics and optimizes the rider’s center of gravity which is unique to Cannondale. The seat tube height has also been reduced to allow for longer dropper posts and more aggressive riding.
Models and local availability
Jekyll 1 is available in a Graphite finish (shown) or Beetle Green and is decked with a Fox Float Factory 38 fork and X2 rear shock. Drivetrain is a combination of SRAM’s GX and XO1 with SRAM’s Code RSC brakes. HollowGram carbon bars and dropper complete the contact points.
Jekyll 2 is available in Purple Haze (shown) or a Graphite finish and is damped by a RockShox Zeb Select Fork and the Fox Float DPX2 Performance Shock. The shifting and braking is via Shimano’s Deore 12-speed and Deore brakes. The bike has a set of WTB STX wheels with a Maxxis Assegai / Minion DHR2 tyre combo.
Local availability is set for early 2022 and pricing will be available closer to then.
