Cannondale Topstone Carbon 4

Nothing is impassable with Topstone Carbon 4

The best gravel bike for everything from dirt roads to singletrack trails. With the grip and comfort of the Kingpin suspension, nothing is off-limits. With plenty of bottle cages and mounts on frame and fork, Topstone Carbon is ready to charge and ride for a long time. Enter the trickiest corners with confidence and come out smiling: thanks to OutFront geometry, Topstone Carbon is stable on rough terrain while remaining agile and easy to ride in other situations.

Kingpin suspension
Increased comfort without the added weight and complexity of joints and shock absorber: Kingpin is the answer for the most demanding gravel users. Whether you need more comfort for long rides, more traction for cornering on the limit, or more absorption for the most technical trails, - Kingpin is the lightweight, maintenance-free answer to your prayers.

Engineered simplicity
Low-friction bushings on the Kingpin suspension pivot ensure smooth operation, maintenance-free reliability, and a saving of over 100g compared to traditional bearings.

Tyre size and compatibility
New low-profile design allows you to use tyres up to 700x45mm or 27.5x2.1", leaving 6mm of wheel clearance on both sides and standard camber for easy wheel changes.

Specific to each user
Size-specific Proportional Response construction provides optimal stiffness for each frame size, so everyone gets the superb riding feel Synapse is known for.

SmartSense Ready
Make every ride better with increased visibility and safety. The SmartSense-ready frame makes it easy to integrate the bike with our light and radar rearview system.

OutFront Geometry
Secure stability and agile handling. An elongated fork offset combined with an open head angle keep the steering lively and easy to steer, while still offering high safety at high speeds and in rough terrain.

Always connected
Via Cannondale's free app, the integrated wheel sensor acquires highly accurate information on speed, route and distance travelled. It also allows you to register your bike, reminds you to perform maintenance and offers many other services.

Prepared for telescopic seatpost
This bike is compatible with a 27.2 mm telescopic seatpost with internal cable routing, a must for a two-wheeler designed for off-road use.
