Cannondale Jekyll 3 29" Carbon/Alloy Disc Mountain Bike 2020
A highly capable enduro build that combines a BallisTec carbon front triangle with SmartForm C1 Alloy aluminium swingarm, the Jekyll 3 29" Carbon/Alloy Disc Mountain Bike from Cannondale is packed with performance features for hard and fast riding. The geometry uses the proprietary Asymmetric Integration that pulls the stay in at the rear for a snappier ride feel with bags of traction. Tyre clearance is wide and the engineering has achieved exceptional stiffness so that the performance is controlled and power transfers straight to speed on the trails.
A LockR thru-axle pivot system stabilises the bike by creating a bombproof connection with both sides of the swingarm, eliminating unwanted flex or twist, and the servicing doesn't require any special tools. SRAM GX Eagle components with an 11-50t cassette and 1X drivetrain deliver plenty of range for any terrain so that once you have blasted the timed descents you can easily spin to the start of the next stage on the enduro course. As an extra bonus, there is enough space in the front triangle to mount a standard bottle and cage.
Features
- SRAM GX Eagle 12-speed components with 11-50t cassette and 30T chainring
- Enough space in the front triangle to fit a standard water bottle
- Ultra short chainstays and Ai rear end
- Wide tyre clearance and incredible stiffness
- Cannondale DownLow Dropper seatpost with internal cable routing
