Best blend of fast and fun! Race-inspired technologies and features that were copied directly from the higher-priced brothers. Incredible performance at a remarkable price. Lightweight tubes, noble dropouts and sophisticated SAVE features characterize this robust Cannondale frame. It is made of 661 aluminium alloy and heat-treated to a T6 hardness for strength and durability. The Trail 4 is equipped with classic and robust components that are proven and established. Shimano Alivio shifting components provide a smooth 3x9-speed performance. Hydraulic Shimano M315 disc brakes and a SR Suntour XCM-RL air suspension fork with 1 mm travel and remote lockout complete this fine MTB.
