Cannondale Jekyll 1 29" Carbon/Alloy Disc Mountain Bike 2020
The Cannondale Jekyll 1 29" Carbon/Alloy Disc Mountain Bike features an innovative collaboration with Fox, the Gemini Shock, that adds two new ride modes - Hustle and Flow - to the Fox Float Factory rear shock. Hustle keeps things tight, agile and responsive for when you need the bike to be sharp, snappy and dig in for traction on climbs. Flow is perfect for when the ground gets rough and you need the full travel at your disposal.
The Asymmetric Integration delivers maximum tyre clearance, exceptional stiffness and shorter stays so that the bike is manageable and obedient when the trail is tight and twisty. Using optimal suspension response means that the fork and shock are active even under braking and the LockR thru-axle pivot system ensures a rock-solid connection with both sides of the swingarm so that flex and twisting are a thing of the past.
Shimano provide a combination of their lightweight XT and XTR components to keep the gear shifting sharp and the front triangle even has enough space to mount a normal water bottle - something of a luxury for a full-suspension rig with 150mm of travel.
Features
- Shimano XT and XTR components with 12-speed 10-51t cassette and 30T HollowGram chainring
- Shimano XTR 4-piston hydraulic disc brakes
- 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
- Fox Factory Transfer Dropper seatpost with internal cable routing
- Fox Float Factory performance suspension
- Carbon frame shield
