Campagnolo Ekar 13 Speed Cassette - 9-42

The 1x system works best for gravel, with the 13-speed configuration enabling that to work across a full range of gearing ratios

The precise 13-speed Ekar provides the smoothest gearing progression and the optimum delivery of range.
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 sprocket.
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, 3-/10-sprockets for the range starting with a 10-tooth.
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.
It sits on a new freehub driver body – called N3W – that features on the lightweight carbon Campagnolo Shamal wheelset, with a wide range of compatible wheelsets to follow.
N3W is highly versatile, featuring the same groove profiles as the classic Campagnolo body, but 4.4mm shorter and lighter.
With appropriate lockrings and adaptors, N3W is also compatible with all current and forthcoming Campagnolo 12-, 11- and 10-speed systems, with retro-fit kits including readily available.
As all current disc brake Campagnolo HH12 wheelsets are N3W-compatible you can easily update your wheels ready to run them with Ekar – switching wheelsets is easy and quick!
