Key Features and Benefits:
- KingPin suspension system with thru-axle pivot: Delivers 30mm of rear travel without added weight or complexity. This improves traction and comfort on rough surfaces. The result is better control and reduced fatigue during long rides.
- Topstone Carbon fork with triple braze-on mounts: Adds gear-carrying flexibility while maintaining lightweight precision. The long offset improves front-end stability, giving you responsive steering even on loose terrain.
- Proportional Response frame construction: Each frame size is individually tuned for consistent flex and handling. Riders of all sizes get the same ride quality, ensuring balanced performance across the range.
- Shimano GRX 1x drivetrain with SLX 12-speed cassette: Combines wide-range gearing with simplified shifting. You get reliable performance on steep climbs and varied surfaces without the need for a front derailleur.
- WTB ST i25 rims with WTB Riddler 45c tyres: Tough, tubeless-ready wheelset designed for gravel endurance. This setup offers a dependable grip and smooth roll over rocks, dirt, and uneven roads.
- StashPort downtube storage with StashBag included: Built-in internal storage keeps tools and essentials secure and out of the way. Riders can carry what they need without cluttering the frame.
The main goal for gravel riders is a reliable, comfortable bike that handles long, mixed-surface rides. The Topstone Carbon 3 GRX 1x achieves this with features that reduce vibrations, improve control, and carry gear efficiently. The KingPin suspension, stable geometry, and component mix work together to support longer rides without compromise on performance or handling.
Ready for gravel racing, bikepacking, or weekend exploration, the Topstone Carbon 3 GRX 1x gives you the tools to ride further, smoother, and with more confidence. It's built to meet the demands of real-world terrain and the riders who take it on.
