Cannondale Topstone Carbon 3 GRX 1x (2026)
Simple, capable, and ready for anything, the Topstone Carbon 3 GRX is a full carbon gravel bike that delivers reliable performance on every ride, whether it's a quick lap or a full-day adventure.
The Topstone Carbon 3 GRX strips things back to one chainring and lets the terrain do the talking.
The lightweight full carbon frameset runs Cannondale's Kingpin rear suspension system to take the sting out of rough gravel and loose trails, while Proportional Response size-specific construction keeps the ride dialled for every frame size.
The downtube Stashport keeps snacks and supplies within reach on longer days.
A blended Shimano GRX 820 and GRX 610 groupset pairs a single 40T chainring with a wide-range Shimano SLX 10-51T 12-speed cassette for a drivetrain that handles steep climbs and technical terrain without fuss.
Shimano GRX 610 hydraulic disc brakes with RT70 rotors deliver smooth, reliable stopping in all conditions.
WTB ST i25 tubeless-ready rims on Shimano TC500 hubs keep things durable and dependable, and WTB Riddler TCS Light 700x45c tyres connect you to the trail with confidence.
Cannondale 3 flared alloy bars give you comfortable, gravel-friendly hand positions, and the Cannondale Wheel Sensor keeps accurate ride data flowing to the Cannondale App.
