Campagnolo Ekar 9-42T 13 Speed Cassette

Gravel Specific Gearing
Featuring single-tooth steps across the six smaller sprockets provide the most consistent cadence progression with smooth, efficient changes. Gradually increasing wider spacing features on the larger half of the sprockets. This delivers a natural riding experience and helps you get the best from your performance on testing trails and tough terrain. The cassette is built on two blocks, split 4- and 9-sprockets for the range. For enhanced mechanical resistance, heat-treated carbon steel is used for the core of both blocks, and benefit from a nickel-chrome-satin surface treatment which reduces wear and friction, delivering the optimum durability for gravel riding.

9T Gearing Efficiency
Extensive comparative tests have demonstrated that the 9-tooth is as efficient as any 10 or 11-tooth sprocket on any system, with no additional friction across its narrow-wide teeth, so you don't lose any of the wattage you produce.

Gravel Specific Groupset
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. There is a full range of gearing with smooth, small steps for cadence progression, and a choice of gear ranges to suit the different specialisms within the gravel discipline - each with a wide range, and each with elegantly spaced progressions for smooth changes and no nasty cadence jumps.

13 Speed
From the outset our 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.
