Campagnolo Ekar 13s Cassette

The Campagnolo Ekar 13s Cassette is the foundation of Campagnolo's dedicated gravel drivetrain — a 13-speed cassette built specifically for the demands of off-road and mixed-surface riding. It pairs with the Ekar groupset's single-chainring setup to deliver a wide gear range without the complexity of a front derailleur. Three sprocket configurations let you match the cassette to your terrain and riding style, whether that's fast gravel roads or punishing climbs.

Campagnolo machines these cogs from solid steel blocks — a deliberate choice that prioritizes durability on terrain where grit, mud, and debris accelerate wear. Steel construction adds some weight over an aluminum-heavy cassette, but it holds up where it matters: under sustained load and in conditions that would chew through softer materials quickly. The 13-speed architecture tightens the steps between sprockets, so each shift feels more incremental and composed — you're always closer to the right gear than you would be on a 10- or 11-speed system. That closer ratio spacing translates directly to steadier cadence on varied terrain, which is exactly the kind of riding gravel demands.

Design Benefits

1. Wide range, tight steps: Thirteen speeds across configurations spanning 9-36T through 10-44T gives you the gear range of a wide-ratio cassette without the abrupt jumps between cogs that come with fewer speeds. Whether you're spinning up a long gravel climb or pushing pace on a flat open road, the transitions stay smooth and predictable.
2. Steel construction for real-world durability: Machined from solid steel rather than layered with alloy sprockets, these cogs are built to take the abuse that gravel terrain delivers. Riders putting in high-mileage seasons on rough surfaces will get more consistent shifting performance over the long run compared to cassettes that rely heavily on aluminum.
3. Three gearing options to match your riding: The 9-36T suits riders on flatter gravel routes who want to maintain speed, the 9-42T offers a versatile middle ground, and the 10-44T is designed for riders who regularly face steep climbing or extended loaded touring on gravel roads.
