Name: Cannondale Topstone Carbon 4 2023 - Gravel Bike
Brand: Cannondale

Go ahead, ride it. If your idea of a fun road ride starts where the pavement ends, no other gravel bike can take you further than the Topstone Carbon and its revolutionary Kingpin suspension system. Offered with either a rigid carbon fork, or as a full dual suspension machine with the Lefty Oliver gravel fork, these bikes offer traction, comfort and control beyond the dreams of other drop-bar bikes. On everything from beat-up backroads to full-tilt singletrack, Topstone Carbon lets you get in deep & come out smiling.

Tuned for the Rider

Our Proportional Response size-specific construction creates optimal frame stiffness and compliance for each frame size, so that every rider has the ideal ride feel and comfort of Kingpin.

Engineered Simplicity

New low-friction bushings on the Kingpin thru-axle offer smooth action, maintenancefree reliability and over 100 grams of weight savings vs the previous cartridge bearings.

Clearance and Compatibility

The new dropped chainstay design lets you run big volume tires (up to 700x45mm or 27.5x2.1", with 6mm of mud-shedding clearance on each side), all with a standard dish (nonAi) rear wheel for easy interchangeability.

OutFront Steering Geometry

Confident stability meets nimble agility. An extra long fork offset paired with a slack head angle keeps the steering light and lively, yet delivers unreal confidence at speed and in the rough stuf

Connected

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

Key Benefits

Kingpin Suspension. Delivering a smooth ride without the added weight and complexity of a shock and links, Kingpin is our answer for the most demanding gravel riders. Whether you need more comfort to go long, more traction to push beyond or more give to take on the tech - Kingpin is the maintenance-free, lightweight answer to your prayers.
As You Like It. A configuration for every gravel style. On the 1 and 2 models, choose between the rowdy capability of Lefty or the added security of SmartSense. The 3 is offered with or without SmartSense lights. And the 4 is SmartSense-ready for future upgrades.
Lefty Goes Big. Now designed around 700c wheels, with room for up to 45mm tires, the smoothest, most precise-handling gravel fork in the world has gotten even faster. With bigger wheels and 30mm of bob-free travel, Lefty Oliver gives you the comfort and control to push it harder than ever.
Ride Brilliantly. All new Topstone Carbon models are either equipped with or ready to upgrade to our SmartSense system of rear-facing radar and intelligent running lights. It's never been easier to ride smart.
Load Up. Roll Out. With plentiful gear and waterbottle mounts on the frame and fork, Topstone Carbon is ready to load up and go long.
Corner like a Boss. Rail through the rough and come out smiling. Led by our OutFront steering geometry, the Topstone Carbon offers up handling that's serenely stable in the chop, and light & nimble everywhere else.
