Cannondale F-Si 1 29R Mountain Bike 2017
Introducing the Cannondale F-Si 1 29R Mountain Bike 2017 - your ticket to some serious off-road enjoyment. With this bike, Cannondale has combined their industry leading SmartForm C1 Alloy frame with a range of components that are designed to perform in the toughest conditions.
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 welds on gussets - allowing for a lighter and more balanced frame.
As part of their integrated bike system, Cannondale has utilised their Lefty 2.0 fork with 100mm of travel. This iconic fork provides PBR Isolated Damper Technology to dramatically reduce uncomfortable rebound.
Shimano's Deore hydraulic disc brakes assure confidence-inspiring stopping power through wet or dry conditions. These brakes are mounted to Stan's ZTR tubeless ready wheels, offering you the choice to go tubeless. Schwalbe Racing Ralph Performance tyres keep you firmly anchored to the trail while also maintaining strong puncture protection.
Gearing is provided by Shimano's SLX/XT 11-speed one-by drivetrain. This race-ready groupset adds a SunRace 11-42 cassette for additional climbing power, so you always have the right gear for those tough steep climbs.
FEATURES
- Cannondale's SmartForm C1 Alloy frame ensures the ideal blend of strength, stability, speed and comfort
- Cannondale's iconic Lefty 2.0 fork provides 100mm of shock-absorbing travel
- Shimano's 11-speed shifting is reliable and responsive while the Deore hydraulic disc brakes inspire stopping confidence
