Description
The BallisTec carbon frame used by Cannondale for the F-Si Carbon 5 29" Mountain Bike features their AI (Asymmetric Integration) system, which allows for the use of shorter seatstays without reducing the size of tyre that can be fitted by moving the drivetrain outwards by 6mm. Shorter seatstays mean more weight over the back tyre, so better grip and increased stiffness for power transfer. RockShox’s Reba RL Solo Air fork has 100mm of travel so bumps in the trail are ironed out and grip in corners is increased. The single ring SRAM NX Eagle drivetrain uses a 12-50 tooth cassette paired with a 34 tooth Truvativ Stylo 6K crankset to give a very wide range of gears that are both reliable and simple to operate, whilst the stopping duties are performed admirably by Shimano’s MT500 hydraulic brakes which provide excellent power in all weather conditions. All ready to be set up tubeless, the wheels use WTB STX i23 TCS rims and Schwalbe Racing Ray/Ralph Performance tyres, so the puncture resistance and added comfort can be enjoyed straight away if desired.
