Cannondale Topstone Carbon 1 Lefty AXS

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

Lefty has grown up
The smoothest, easiest handling, most precise gravel fork in the world. 30mm of travel and room for up to 700x45mm tyres make Lefty Oliver the perfect weapon for pushing the limits of comfort and control.

Lefty Oliver Carbon
The ultimate suspension gravel fork. Single-sided design and needle bearing operation provide precise steering and smoothness for unparalleled comfort and control. Only 1340g.

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
Our size-specific Proportional Response construction gives optimal stiffness to every frame size, so everyone gets the superb riding feel the 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 steering angle keep the steering lively and easy to steer, while still offering high levels of 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.

Charge it. Ride it.
With numerous bottle cages and mounts on the frame and fork, Topstone Carbon is ready to be loaded and ride for a long time.

Ride with confidence
Enter tricky corners with confidence and come out smiling. Thanks to OutFront geometry, Topstone Carbon is stable on bumpy roads while remaining agile and easy to ride in other situations.
