The F4X is ready for any terrain, any weather conditions and is fully capable of the most aggressive riding styles. Made from UHC Advanced + TeXtreme carbon fibre that is exceptionally stiff, strong and is super-lightweight. To ensure stiffness when riding on demanding terrain and to provide superb stability this bike has an oversized BB386EVO bottom bracket shell and the wheels are held in place thanks to Syntace style thru-axles. This bike has excellent handling responsiveness and thanks to the modern geometry, its ready to race.
Equipped with a SRAM 1x11-Speed drivetrain and mountain bike inspired SRAM Rival hydraulic disc brakes. This combination means that you will not only be able to accelerate quickly and achieve high speeds offroad, you will also be able to brake competitively and confidently meaning obstacles and off-camber corners can be tackled with more precision. This bike rolls on Felt wheels, which have been tried and tested on Cyclocross events and are more than capable of handling the most demanding tracks and terrain, all season long and beyond.

If you are on the change over between sizes both options will fit. Racers and experienced riders would usually select a smaller size as this offers quicker handing. A larger bike offers more stability and is more suited to new and intermediate riders.
