Always Game - Cannondale Topstone 3 GRX 1x
The Cannondale Topstone 3 GRX 1x the ultimate all-round gravel bike. Go anywhere, bring everything and then keep on going. The Topstone Carbon plays the gravel suspension game like nothing else. Lightweight, long-lasting and easy to maintain, the unique Lefty Oliver and KingPin combo is off-road royalty. Taking the roughest tracks and trails out there and making them feel like champagne gravel. Meaning you can stay on the cranks and carry the momentum to get there first.
One chainring, endless possibilities. The Topstone 3 GRX 1X delivers simplicity without sacrificing performance. A Shimano GRX610/820 blended group keeps shifting precise and reliable, while KingPin suspension takes the sting out of rough terrain. WTB tires keep you connected to the trail, making every ride a good one—whether it’s a quick lap or a full-day escapade.
Highlights
OutFront Steering Geometry: Confident stability meets nimble agility. An extra long fork offset paired with a slack head angle keeps the steering light and lively, yet delivers unreal confidence at speed and in rough stuff.
