Cannondale Scalpel-Si Carbon 4 29R Mountain Bike 2017
Feel the freedom and the fun of XC mountain biking with the Cannondale Scalpel-Si Carbon 4 29R Mountain Bike 2017.
The BallisTec Hi-MOD Carbon frame layup features a geometry that has been honed for the highest level of XC competition. Cannondale has integrated short chainstays for traction and agility, a slack head angle for stability at speed and tight “trail” measurement for nimble handling at slower speeds - all of which combine to make this a truly remarkable XC frame.
Integrated with this frame is Cannondale's iconic Lefty 2.0 Carbon fork, which offers 100mm of travel as well as advanced XLoc Full Sprint remote lockout technology for rapid lockout when you need it. The rear shock is a RockShox's Monarch RL with 100mm of travel.
Shimano's XT hydraulic disc brakes assure confidence-inspiring stopping power while the XT gearing and Cannondale Si crankset make sure you've always got the right gear when it comes to tough terrain.
Stan's NoTubes ZTR Rapid 25 wheels come tubeless ready with Schwalbe's Racing Ralph Performance tyres for optimal traction, rolling resistance and puncture protection.
