Campagnolo Ekar

Ekar is the world’s lightest gravel groupset (under 2.4kg): reliable, durable & fast. With a wide range, close ratio and no compromise, Ekar is designed from the ground up to give you the very best performance, riding experience and reliability for gravel, all-road and endurance riding on the toughest terrain where you want to face and challenge yourself. From the outset Campagnolo's engineers and design team tested and pursued the route of a 1x system being the best for gravel, and engaged with the challenge of creating the best possible implementation – and the light, efficient, precise 13-speed Ekar is what delivers.

Smooth, wide range gears.

A 10-44 cassette teamed with a 42 tooth carbon crankset ensures there is a full range of gearing with smooth, small steps for cadence progression, elegantly spaced progressions for smooth changes and no nasty cadence jumps. 1x offers maximum efficiency, no wasted gearing overlaps, and superior chain retention security. Its gears are designed to be gravel-specific with deliberate and natural-feeling progressive cadence control: 1-tooth steps for small sprockets and bigger steps for larger sprockets – for speeds to match every route.

Powerful hydraulic brakes.

Ekar features the best of proven Campagnolo disc brake performance and modulation, optimised for the very best gravel riding performance.

Offering big tyre clearance and a sure-footed handling, the Free Ranger is a gravel bike at heart with speed and efficiency in mind. With additional mounting points for bags, theres no reason why it wont be the dream platform for some fast multi-day bikepacking expeditions too. If youre a road rider looking to get into gravel, or simply like going fast on your gravel rides, then the Free Ranger will fit the bill perfectly.



Controlling the shifting is Campagnolo's sleek and smooth Ekar 13 speed drivetrain. With a wide range 10-44 cassette, you'll find a perfect gear for every gradient. The stiff carbon crank, clutch derailleur and narrow-wide chainring will allow you to power over rough terrain with minimal chain noise. Ekar brakes provide power and control within any stopping distance whatever the weather.



Tubeless ready Fulcrum Racing 500 DB wheels provide lightness and durability. A fast-engaging freehub, aerodynamic rim profile and stiff build will ensure you'll get back what you put in when putting the power down.
