Cannondale F-Si Hi-Mod World Cup Replica 29" Mountain Bike 2020
Go chasing podiums and ambitious race goals with the high calibre Cannondale F-Si Hi-MOD World Cup Replica 29" Mountain Bike. Dripping with the finest components straight from the top drawer, this is a build that's refined for slaying XC race courses and powering you to your best results yet. Riding like a pro should come easily on a bike that's ridden by some of the fastest riders in the world, especially when the tech delivers all the necessary prerequisites for power, control and responsiveness.
The Hi-MOD BallisTec frame is exceptionally light and is engineered with SAVE technology that boosts control and comfort in the rear triangle. The Lefty Ocho fork is stiff and light and delivers the smoothest ride experience, whilst it's also capable of being easily locked out to power up the climbs. It combines perfectly with the Asymmetric Integration drivetrain that makes traction readily available when you really need those extra watts instantly.
SRAM's flagship XX1 Eagle AXS wireless electronic off-road groupset brings game-changing gear shifting to your setup. Enjoy the perfect chainline, tactile and effortless shifting, simple maintenance and in-app personalisation for a bespoke feel that best suits your ride style.
Finishing off the build in style are ENVE M525 carbon wheels, an ENVE carbon handlebar and ENVE carbon seatpost, and the integrated wheel sensor lets you see in detail just how much faster your performances are getting.
