Cannondale Topstone Sora Disc Gravel Road Bike 2020
Whether you are looking to take up bikepacking, plan some new adventures or just need a robust bike to tackle the grind of a daily commute, then the Topstone Sora Disc Gravel Road Bike from Cannondale could be the perfect option. The frame has space for wider tyres that will enhance comfort and control, whether rolling through country lane potholes or down backcountry gravel roads, and the geometry delivers the right balance for endurance riding and speed. A full carbon fork adds an extra touch of comfort and the 12mm thru-axle with tapered steerer enables light and responsive steering for predictable handling no matter the conditions.
The Shimano Sora components, including cable actuated disc brakes, are durable in all situations and with a 9-speed 11-34t cassette paired with a 46/30T crankset, you will have plenty of gears to get up the toughest climbs.
- Built with plenty of room for tyres up to 42mm wide, for comfort, grip and adventurous capability
