The Perfect Gear For Any Terrain

Campagnolo's new Ekar 1x13 speed groupset is the ultimate mechanical gravel groupset. The 13 speed combination paired with wide range cassettes gives you tons of range to crawl up the steepest of hills or bomb epic descents without spinning out.

The Ekar cassettes feature either a 9 or 10 tooth cog for the biggest cog and a 36, 42, or 44 tooth cog for the smallest cog. The incredible part is that a 9T cog paired with a 42T chainring offers almost the same top end gear as a 11T cog paired with a massive 52T chainring. That means you'll get the same top end gearing as a 2x drivetrain but with the same climbing gears as a traditional 1x11 gravel groupset.

The 9-36T combo offers very small gearing steps and has a closer range of gears for more of a road-oriented feel, the 9-42T combo is a great middle ground option if you need a big top gear and a big easy gear for steep climbs, and the 10-44T combo is the ideal cassette if your adventures require mountain-grade climbing gears.

The nickel-chrome-satin surface treatment helps to reduce wear and friction which saves you precious watts while simultaneously reducing cassette wear. The heat-treated carbon steel body is solid, durable, and long lasting.

Whether you're just replacing your Ekar cassette or starting your dream gravel build, Ekar's new 13-speed cassette range has got an option for you.
