Cannondale Topstone Tiagra Disc Gravel Road Bike 2020
The Cannondale Topstone Tiagra Disc Gravel Road Bike is packed with features to help you dial in your gravel riding and explore new roads that standard road bikes just wouldn't be capable of doing. The frame can cater for up to 42mm wide tyres that are ideal for absorbing the lumps of broken surfaces and for inspiring confidence when descending on loose terrain or in poor weather.
A full Shimano fork with front thru axle pairs perfectly with the endurance geometry, so the bike feels comfortable for long days in the saddle, but still has an underlying race edge with nimble handling, should you wish to push the pace. A mechanical Shimano Tiagra groupset has plenty of gears to make light work of long climbs and when it comes to setting up the bike for multi-day trips, the various bottle cage and storage mount points let you set up your kit exactly as you need.
- Built with plenty of room for tyres up to 42mm wide, for comfort, grip and adventurous capability
- A slack head angle paired with a long 55mm fork rake delivers great stability at speed
- Multiple bottle cage positions on the downtube mount let you configure for big frame bags
- Full carbon fork with tapered steerers and 12mm front thru-axle
- Full Shimano Tiagra groupset
- Tiagra hydraulic disc brakes
