Cannondale Topstone CAAD 1 GRX 2x: Ready for Any Route

The Cannondale Topstone CAAD 1 GRX 2x is designed for riders seeking a gravel bike that can confidently handle paved roads, unpaved tracks and long-distance rides. The high-quality aluminium frame, developed in line with Cannondale's CAAD philosophy, combines strength, low weight and precision, delivering balanced handling for both sporty rides and everyday adventures.

CAAD Aluminium Frame and Carbon Fork

The SmartForm C1 aluminium frame is designed to provide strength and responsiveness, with geometry engineered for stability and agile handling. The all-carbon Topstone Carbon fork contributes to precise front-end handling and features mounting points for water bottles and accessories. The OutFront geometry, with a 55 mm fork offset, enhances stability at high speeds while maintaining agile handling on tighter sections.

12-Speed Shimano GRX 2x Drivetrain

The 12-speed Shimano GRX drivetrain with a 46/30-tooth double chainring is designed to deliver versatility across a wide range of routes. Paired with a Shimano 105 11–36 cassette, it provides suitable gearing for fast paved sections as well as climbs and more demanding gravel terrain. The Shimano GRX system ensures precise and reliable shifting on gravel rides.
