Cannondale Topstone 3 Gravel Bike 2021
Get out and explore more on the Cannondale Topstone 3 Gravel Bike. An excellent introduction to the world of gravel riding, this bike is ready for adventure. With a lightweight carbon fibre fork combining with a strong alloy frame, this gravel bike handles nicely while offering robust durability for thousands of off-road miles.
The wide-ranging gearing ratio comes courtesy of an 11-34t cassette and sub-compact chainset, all operated by the Shimano Sora 2x9-speed levers and derailleurs for quick and easy shifting. The wheels are built to last too, and come fitted with 37mm wide WTB tyres, which give excellent traction and stability off-road while maintaining enough speed on the tarmac to ensure you get to the trails fresh and ready for fun.
- Strong and reliable Cannondale C2 Alloy frame
- BallisTec Carbon fork provides vibration-reducing lightweight steering
- Large volume 37c clincher tyres from WTB offer offroad stability
- Shimano Sora gearset shifts with ease
- Mechanical disc brakes are great for muddy conditions and are easier to maintain
