Description
Combining a full carbon frame and fork with gravel-specific components, the Cannondale Topstone Carbon 3 Gravel Bike is adventure-ready. Be it back roads or technical singletrack, this bike is built to deliver traction, control and comfort. Kingpin suspension is key to the high compliance, adding rear, bump-absorbing suspension and the OutFront steering geometry provides a nimble yet stable ride.
Shimano GRX 600 components provide a wide range of gears and Shadow technology reduces the chances of chain slap or drop over even the roughest terrain. Hydraulic discs ensure stopping is fast in all conditions. WTB 700c wheels are fitted with wide 700x45c tyres and the frameset is also compatible with 650b tyres up to a 47mm width too, so you can go wider still if preferred. The inclusion of a Cannondale Wheel Sensor enables you to gain information about your speed, distance and route via the free app.
