Innovation AND Technology

KingPin Suspension System

Topstone Carbon
KingPin Suspension System

Up to 30mm of bump-smoothing suspension, without the weight and complexity of a shock or linkages.

Proportional Response Construction

Topstone Carbon
Proportional Response Construction

Suspension and overall frame ride-feel is custom tuned by size, using different carbon layup and different tube dimensions, so each size is dialed for the rider. Just get on and go.

Connected

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.

LockR Pivot

LockR Pivot

Thru-axle pivot locks the left and right seat-stays together, preventing independent rotation for a solid feel and instantaneous response.

Dialed Endurance Fit

Topstone Carbon
Dialed Endurance Fit

Offers a perfectly balanced riding position: upright enough for comfort over the long haul and control when tackling technical off-road terrain, yet still low and forward enough for speedy efficiency.

OutFront Steering Geometry

Topstone Carbon
OutFront Steering Geometry

Keeps the steering light and agile, while positioning the wheel further in front of the rider for stability and confidence on rougher stuff. Plus it reduces the chance of toe overlap on smaller sizes.

Big Tire Clearance

Big Tire Clearance

Comes with big 700x37c tires for grip and comfort, but has room for up to 40mm tires with tons of clearance. You can even put on 650 wheels with 48mm tires if small and fat is your thing.

Carry That Gear

Topstone Carbon
Carry That Gear

Plenty of places to store gear and water, with a multi-position mount on the downtube, and more on the top tube, seat tube, and under the down tube. There's even mounts on the forks.

Fender Up

Topstone Carbon
Fender Up

Fully fender ready. A removable fender bridge on the rear stays is there when you need it, gone when you don't.

Speed Release Equipped

Topstone Carbon
Speed Release Equipped

Speed Release thru-axles offer the stiffness and solid feel of a thru-axle, with the easy use of a quick release axle. Compatible with most thru-axle wheelsets.

Easy Internal Cable Routing

Topstone Carbon
Easy Internal Cable Routing

With our DirectLine cable routing, an internal tube guides the cable and housing through the frame, from entry to exit for headache-free service.

Dropper Ready

Topstone Carbon
Dropper Ready

Built to accept an internally-routed 27.2 dropper seatpost, which shouldn’t really be a surprise on a bike that's this off-road capable.
