Cannondale (United States) - Press Release: Topstone Carbon. An unprecedented gravel bike with real suspension. The most capable off-road, the most comfortable on-road.

An evolution of the species:

Topstone Carbon distills our experience making fast race bikes, comfortable endurance bikes and ultra-light dual suspension mountain bikes into the most off-road capable, and on-road comfortable, road bike ever made. Designed for maximum fun in places most gravel bikes would fear to tread, or maximum comfort in more sedate terrain.

KingPin Suspension:

Revolutionary, super-light suspension that lets you ride harder on dirt and more smoothly on pavement. Better control. Better traction. Better comfort. Nothing sacrificed.

Up to 30mm of suspension, without the weight and complexity of a shock or linkages. A special thru-axle pivot in the seat tube allows engineered flex zones in the rear triangle and top tube to do their magic, absorbing bumps and vibration and improving comfort, traction and control whether you're seated or standing.

Every Rider is Different - Proportional Response Construction:

Suspension and overall frame ride-feel is custom tuned by size. We manipulate the carbon layup and tube dimensions to deliver the right amount of flex and stiffness for the rider’s size, so all you need to do is get on and ride.

It’s Easier to Go Harder:

Refined geometry and rider position deliver an experience that’s stable, composed and comfortable without losing that spark. Go further, ride longer, charge harder.

The Last Detail:

We thought of everything. Big clearance for big tires. Tons of gear and storage mounts. Speed Release thru-axles. DirectLine cable routing. Internal dropper post compatibility. In short, the works.

Connected:

An integrated wheel sensor delivers hyper accurate speed, route and distance info, registers your bike, reminds you of needed service and more, all through the free Cannondale App.
