Always Game
Cannondale’s take on the ultimate all-round gravel bike. Go anywhere, bring everything and then keep on going.
Model Description
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.
