Cannondale Topstone Carbon 3 GRX – 1x Gravel Bike

The Cannondale Topstone Carbon 3 GRX – 1x is built for riders who want the freedom to go further, explore deeper, and ride longer. Whether you're chasing gravel adventures, bikepacking escapes, or all-day mixed-surface rides, the Topstone delivers comfort, capability, and performance in one incredibly versatile package.

At the heart of the bike is Cannondale’s lightweight Topstone Carbon frame paired with the innovative KingPin rear suspension system. This clever design provides real rear-wheel compliance without adding weight or complexity, smoothing rough terrain and improving traction while maintaining efficient power transfer.

The drivetrain blends Shimano GRX820 and GRX610 gravel components with a wide-range 12-speed Shimano SLX cassette. Combined with the simplicity of a single chainring, this setup delivers reliable shifting and a huge gear range for steep climbs, fast gravel descents, and long adventure rides.

Adventure-ready details like the StashPort downtube storage system, multiple mounting points, and wide WTB Riddler 45c tubeless-ready tires make the Topstone Carbon 3 ready for everything from quick gravel loops to multi-day bikepacking missions.

Available now at Mackay Cycles — your local destination for performance gravel bikes in Mackay and across Queensland.
