Cannondale Jekyll 2 27.5" Mountain Bike 2019

Hit the trails on a mountain bike packed with all the technology you could possibly need to make you kick harder, corner faster and climb more efficiently. The Cannondale Jekyll 2 has 27.5 inch wheels to improve performance on technical trails, and the Maxxis Minion tyres offer exceptional traction. The geometry features Asymmetric Integration (AI) and improves handling, making for a more nimble feel, while keeping tyre clearance and frame stiffness high.

Constructed from BallisTec carbon fibre, and with a SmartForm C1 rear swingarm, you get the best balance of light weight, stiffness and durability. To the front, the Fox Float 36 Performance Elite fork provides 170mm of travel, and to the rear, the shock features the Gemini dual mode system so you can alter travel to suit. 'Flow' mode, with 165mm of travel, is ideal for flowing, fast downhills and when you hit the hills, 'Hustle' mode limits the travel to 130mm for easier climbing.

The SRAM Eagle drivetrain complements this top end frameset perfectly and makes for smooth, fast and reliable shifting. The hydraulic disc brakes and 200mm and 180mm rotors, front and rear respectively, ensure braking is powerful, for confidence inspired descending.


  • Full BallisTec carbon frame, with carbon shock link, for the ultimate lightweight Enduro machine
  • Fox 36 Float Factory fork, with super supple 170mm travel to soak up every lump and bump of the trail
  • Fox Float X Factory rear shock with high-volume EVOL canister delivers smooth and predictable suspension, with Gemini remote switching between 165mm and 130mm of travel
  • Asymmetric Integration - Ai delivers some of the shortest stays on the trail
  • LockR thru-axle pivot system creates a rock-solid connection between both sides of the swing arm and the main frame for instantaneous response. No twist, no flex, and no special tools required
  • SRAM Eagle groupset for reliable and smooth shifting, and 200mm/180mm rotor hydraulic disc brakes for powerful stopping
  • Clean cable management
  • Perfect bottle placement - Water at arms reach and out of the way of the dirt spray
