Cannondale SuperX GRX Disc Cyclocross Bike 2020
The full carbon Cannondale SuperX GRX Disc Cyclocross Bike is fast and light - quick in the sprint and easy to shoulder should you need to hoist it over obstacles. Cannondale's Outfront Steering Geometry is stable in technical descents so that you have the confidence to hold speed and not relinquish time to others, whilst still remaining agile elsewhere on the course. Thru-axles keep the stiffness high for responsive power transfer and deliver control under braking.
The unique Ai offset drivetrain means that chainstays are kept short for the snappiest handling that will obediently change direction when required and also allows for a massive tyre clearance so that you won't get clogged up on mud-heavy courses.
The 1X drivetrain keeps maintenance low and cleaning easy for your pit crew and again helps to prevent dirt from slowing up the gear changes, and Shimano GRX levers are textured for grip when the conditions are wet so that you never get caught in the wrong gear.
- Shimano hydraulic disc brakes
- Clean cable management - interchangeable cable guides hold the housing securely and support any cable configuration
- Exceptional traction when the course is wet
- Full carbon frame and fork
- Thru-axles for stiffness when you need more power and control under braking
