Perhaps the most overlooked, yet most critical component of your bicycle is the chain. That's not the case with Campagnolo though, as they take great pride in making some of the most efficient and resilient chains on the market. That remains true for the new Ekar gravel groupset, which despite being the narrowest chain Campy has ever made (in order to accommodate the 13-cog cassette), retains the crisp shifting and proven reliability we've come to expect from their 11 and 12-speed chains. A corrosion-resistant, low-friction Nickel-Teflon coating keeps your drivetrain running smooth and quiet, and the chain mates perfectly with the Ekar narrow-wide chainring for unflappable chain retention in rough terrain.
