Cannondale F-Si Carbon 5 Mountain Bike 2021

With a carbon frame that weighs in at just 900 grams, the Cannondale F-Si Carbon 5 Mountain Bike is super light and built for XC thanks to serious compliance, rugged durability and race-ready responsive handling that's aided by the Ai Offset drivetrain and OutFront steering geometry. The FOX Float Factory 32 SC fork lends 100mm of travel to smooth out rough terrain whilst maintaining precise steering and keeping weight low. 

1x12-speed SRAM NX Eagle components keep shifting crisp, with the single front chainring simplifying maintenance and minimising any mid-ride complications. Let the burly 29" wheels carry rolling momentum over obstacles with ease and take speed off in an instant with the sure stopping power of Shimano MT500 hydraulic disc brakes, should a corner or descent have been taken a touch too enthusiastically. 

Highlights

  • Asymmetric Integration drivetrain for podium-level traction and clearance
  • Proprietary BallisTec carbon is custom-tuned for rigidity, compliance and weight-saving
  • Shimano MT500 hydraulic disc brakes
  • FOX Float 32 SC fork
  • Clean, configurable internal cable routing
  • SRAM NX Eagle 1x12-speed components
