Cannondale F-Si Carbon 4 Mountain Bike 2017

With a premium BallisTec Hi-MOD carbon frame construction, the Cannondale F-Si Carbon 4 Mountain Bike offers an ultralight and strong frame for riders looking to take their off-road riding to the next level.

Cannondale's premium BallisTec Hi-MOD Carbon frame construction allows the bike to not only be light but also ultra-stiff, strong and responsive. For the fork, Cannondale has employed their iconic Lefty 2.0 fork, which offers 100mm of travel and its XLoc lockout allows you to put the power down when you need to.

In order to get you up and over those tough gradients, you are going to need a wide and accommodating range of gears. That is exactly what Shimano 11-speed drivetrain and SunRace cassette provide. With a 26/36 crankset and 11-40 cassette, this bike offers the ultra-low gears needed to power up and over steep climbs and the higher gears needed for building speed on descents.

Braking is provided by Shimano's Deore hydraulic disc brakes. These confidence-inspiring brakes provide the modulation and power required for tackling the trail at full speed - no matter what the conditions are.

WTB i19 tubeless ready wheels provide strength and stability, while the Schwalbe Racing Ralph Performance tyres keep you firmly gripping the trail.

FEATURES

  • Cannondale's premium BallisTec Hi-MOD Carbon frame construction optimises low weight and stiffness while also featuring a geometry that is ready to tackle the toughest XC courses
  • Tubeless Ready wheels offer versatility
  • The iconic Lefty 2.0 fork with 100mm of travel, keeps you comfortable over the rough stuff and big drops
  • Shimano's 11-speed shifting is reliable and responsive
