The Cannondale Topstone Carbon 3 Shimano GRX 2025 is a gravel bike designed for those who want to explore further, ride faster and push the limits of comfort and versatility. With its lightweight carbon frame and Kingpin rear suspension, it turns every ride into a smooth, responsive and highly enjoyable experience, whether on lesser-used tracks or on your daily commutes.
At the heart of the Topstone Carbon 3 is the renowned Kingpin suspension, an ingenious system that delivers exceptional comfort and control without using a conventional shock. Combined with the Proportional Response construction, which tailors frame stiffness to each size, this technology ensures consistent, balanced behavior for all riders. The integrated StashPort on the downtube adds a welcome practicality, allowing discreet storage of tools and essential accessories. Internal cable routing, multiple mounts for bottles and gear, and compatibility with dropper seatposts further enhance the versatility of this modern gravel bike.
The Topstone carbon fork, featuring OutFront offset, provides remarkable stability on technical terrain while retaining confident, agile handling. This signature Cannondale design inspires absolute confidence as speeds rise or trails get rougher. The riding position is both sporty and comfortable, allowing long hours in the saddle without unnecessary fatigue.
On the drivetrain side, the Topstone Carbon 3 relies on a premium Shimano GRX mix combining GRX820 and GRX610 in a single chainring (1x) setup. With its wide-range SLX cassette and 12-speed gearing, the bike offers impressive versatility, handling long climbs and rolling sections with smoothness and precision. The GRX610 hydraulic brakes deliver consistent, controlled stopping power—essential for maintaining control and confidence on descents or in wet conditions.
The build rolls on WTB ST i25 tubeless-ready rims, robust and reliable, shod with excellent WTB Resolute 42 mm tires, ideal for absorbing terrain irregularities while preserving efficient rolling. The cockpit, made up of the flared Cannondale 3 handlebar and the C1 Conceal stem, ensures a stable position and precise steering, specifically tuned for modern gravel demands. To complete this premium configuration, the Topstone Carbon 3 includes a Cannondale wheel sensor, allowing speed, distance, route or maintenance programs to be tracked directly from the dedicated app.
The Cannondale Topstone Carbon 3 Shimano GRX 2025 is a bike designed for riders who want a machine that is simultaneously high-performing, comfortable and incredibly adaptable. Whether exploring forgotten trails, pushing on the road or heading out for bikepacking, it responds with elegance, efficiency and reliability. Every ride becomes a new opportunity to go further.
