Cannondale F-Si 3 29R Mountain Bike 2017
Value, performance and trail-shredding fun - all are embodied in the Cannondale F-Si 3 29R Mountain Bike 2017. Cannondale has engineered their SmartForm C1 Alloy frame with double-pass welds to provide stronger, smoother joints and eliminate the need for internal reinforcements or external welded-on gussets - allowing for a lighter and more balanced frame.
Combine this industry-leading aluminium frame with the RockShox Recon Gold RL fork and you have a serious XC pedigree that rivals those at a far higher price-point.
Shimano's M445 hydraulic disc brakes assure confidence-inspiring stopping power through wet or dry conditions. Cannondale's own DC 3.0 wheels are ready to handle the toughest trail conditions and their 29R size helps to maintain speed and traction out on the trail. Schwalbe Rabid Rob Performance tyres keep you firmly anchored to the trail while also maintaining strong puncture protection.
XC mountain biking fun requires an accommodating gear range that will not leave you wanting on tough climbs. Luckily, Cannondale has utilised a Shimano's SLX/XT drivetrain with an FSA Comet MegaExo crankset and SunRace cassette to keep you confidently pedaling over tough climbs.
FEATURES
- Cannondale's SmartForm C1 Alloy frame ensures the ideal blend of strength, stability, speed and comfort
- RockShox's Recon Gold RL fork offers 100mm of travel and a useful remote lockout feature
- Shimano's 11-speed shifting is reliable and responsive while the M445 hydraulic disc brakes inspire stopping confidence
