Cannondale Topstone 1 Gravel Bike 2023
Cannondale's Topstone 1 is built for adventure. This extremely capable gravel bike combines a strong SmartForm C2 alloy frame with a carbon fork and Shimano gravel-specific components to deliver comfort and good traction over all terrains while keeping weight to a minimum. OutFront steering geometry with a longer fork and slacker head angle creates an agile ride feel with plenty of stability.
The frame and fork incorporate plenty of mounts for bottles, mudguards and luggage, and the WTB wheels have been fitted with wide 35mm Vittoria tyres to soak up the bumps. There's room to go even wider – 45mm – if preferred. When tackling steeper, trickier terrain, you may appreciate the ability to swap out the seatpost for a dropper post.
GRX 800 and 600 are Shimano's highest-level groupsets that are aimed specifically toward gravel riding. Shadow technology in the rear mech provides chain stability and the cassette and chainring combination give a wide gear range to help manage both the ups and downs. Hydraulic discs ensure powerful stopping as and when required, in all conditions.
