Clearance for big volume tyres grants increased traction and comfort over rough terrain.

Cannondale Topstone Carbon 4 Gravel Bike 2021

For riders who enjoy nothing more than spending long days in the saddle, seeking out new routes unbound to the limits of tarmac, the Cannondale Topstone Carbon 4 Gravel Bike is a superb companion. The BallisTec carbon fibre frame and fork deliver a light handling bike that surges when you give it a push, while the Kingpin suspension system really boosts compliance and comfort.

Ensuring you make the most of your riding off-road, Cannondale has specified the excellent Shimano GRX 800 groupset, with some key features that make riding the rough stuff a pleasure. The rear derailleur boasts a clutch mechanism which dramatically reduces chain slap, so you can ride harder over bumps. Shifting is quick and light, and the hydraulic disc brakes provide all the stopping power you need, in wet or dry conditions.

Cannondale's much-admired OPI SpideRing crankset comes with sub-compact chainrings and is paired with a wide 11-34t cassette so you can head off without fear of steep hills, and you'll have enough gears to keep up with friends on road bikes too. The wide WTB 37mm tyres come tubeless-ready along with the rims, so you can choose to set them up without tubes for even lower pressure and better traction on the trails.

  • Gravel specific Shimano GRX groupset
