Cannondale Topstone Carbon Lefty 1

Retul bikefits only £99 with all cyclecross and gravel bikes


The Topstone is Cannondale’s all out gravel bike range, covering single and dual suspension, carbon and aluminium frame options.

This Topstone Lefty 1 is the very top end of the range. It’s built around a full carbon frame, fork and wheels maximising handling, comfort and traction via its dual suspension technology. This comes in two forms : the Oliver Lefty full front suspension fork and the Kingpin rear suspension system offering up to 30mm of travel in the back end for maximum bump absorption and comfort. This bike takes “extreme” gravel in its stride.

The 1x SRAM 40t crank and SRAM Eagle eTap wireless shifting on the wide ranging 10-52t cassette gives ample gearing for very hilly terrain and helps to reduce the overall weight, as does the addition of Cannondale’s own super lightweight HollowGram bars, stem, and seatpost.

The bike ships with smaller, more agile 47c tubeless ready 650B tyres on Cannondale’s own HollowGram rims making any outing about as much fun as you can have on a bike.

For the techies amongst us, an integrated wheel sensor delivers speed, route and distance info and much more direct to a linked App.

Complete with multiple mountpoints for luggage and gear, the Lefty is your sublime partner for gravel roads, trails and hills while maintaining a precise and sharp feel for the (hopefully limited) tarmac road.
