Cannondale Topstone Carbon Lefty 3 Gravel Bike 2021 Green

Season : 2021

Brand : Cannondale

Code : C15151MMantis

More Give. More Go. More Lefty. A gravel bike to beat all gravel bikes. Dual suspension makes this the most off-road capable and on-road comfortable road bike ever made.

Dual Suspension

It had to happen. We paired our proven, super-light and effortlessly simple Kingpin rear suspension system with our cutting-edge, built-for-gravel Lefty Oliver 30mm gravel suspension fork – meaning better control and even more comfort.

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.

Grip, Comfort and Control

Topstone Carbon Lefty comes with smaller diameter, higher volume 650 x 47c tires for even more off-road ability and on-road comfort.

The Last Detail

We thought of everything. Tons of gear and storage mounts. Speed Release thru-axles. Rear fender mount. Internal dropper post compatibility. In short, the works.
