Cannondale Topstone Carbon LTD Lefty Axs 2025

The take on the ultimate all-round gravel bike. Go anywhere, bring everything and then keep on going

This is the pinnacle—the very best of the all-round gravel machines. Buttery-smooth dual suspension lets you float over unpredictable terrain without losing an ounce of speed. KingPin offers up to 30mm of travel in the rear, while the updated Lefty Oliver Carbon fork gives you 40mm up front, keeping things fast, smooth, and suspiciously fun. SRAM Force AXS XPLR clicks into place like it’s reading your mind, and Reserve 40|44 GR carbon wheels stay rock steady through every twist and turn. From endless backroads to the toughest race days, this bike sets the bar for speed, control, and all-terrain capability.

Smiles for Miles
Kingpin is the lightweight, go-for-longer rear suspension. Maintenance-free and complexity-free, it gives the Topstone frame legit rear-wheel travel without compromising stiffness for the sprint. Kingpin provides a smoother ride, more traction to push harder, and more give to take on the rough stuff. You’ll hardly know it’s there, but you’ll be very glad you’ve got it.

Lefty Feels Right
After a decade on the roads, Lefty Oliver still wows with its unique look and gravel-taming performance. 40mm of travel in a stiff, lightweight design boosts confidence and control for faster rides. And with 100-hour service intervals – double that of most forks – it brings low maintenance for more ride time and less down time.

Bring It All
The all-new StashPort storage system in the downtube is designed to be concealed yet convenient. Paired with the special StashBag, you can bring your essentials along for the ride and know that they’ll be kept safe, whatever you get up to out there. Meanwhile, multiple mounting points on the frame, mean more gear and more adventures.

Tuned Ride
A dialed-in ride, just for you. AKA: Proportional Response Construction. Everything from the carbon layup to the geometry on Topstone is individually tuned by frame size. So that the bike – including KingPin suspension – works in harmony to give you the best ride for you and your dimensions.

KingPin
The innovative rear suspension is incredibly light, simple and effective. A through-bolt in the seat tube allows the bike's rear suspension and seatpost to flex vertically, offering up to 30mm of travel to absorb shocks without adding complexity or weight.

Lefty Oliver
Lefty Oliver is Cannondale's ultra-light single-sided suspension fork for gravel bikes, offering 40mm of travel and incredible steering precision for improved control and comfort over rough terrain.

StashPort + StashBag
StashPort is the idea of a storage system on the down tube, accessible under the bottle cage. Each bike is equipped with StashBag, a specially designed bag to hold essential items.

Wheel passage
Topstone Carbon can mount tyres with a maximum measured width of 52 mm for the frame and 56 mm for the rigid fork. The wheel passage of the Lefty Oliver is optimised for 700x47 mm tyres, with height being the main limiting factor.

Telescopic seatpost ready
This bike is compatible with a 27.2 mm telescopic seatpost with internal cable routing, which should come as no surprise on a bike designed for off-road use.

Proportional Response
Optimised specifically for each rider, the size-specific construction ensures optimal stiffness and comfort for every frame size. So every user can benefit from the ideal riding feel and comfort offered by KingPin.

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.

Clean integration
The internal routing of the sheaths throughout the frame, combined with the Conceal stem, give the bike a neat, integrated look.
