A drivetrain – in fact, a bike – is nothing without a chain to make it all work. And in Campagnolo’s ground-up design of the 1x13 Ekar drivetrain, they kept that fundamental component front and centre of their focus. They knew it had to be a vital element in operating effectively and reliably in the toughest environments gravel and all-road riding can throw at you. The new Nickel-Teflon treated C13 chain is designed specifically to work efficiently and securely with a narrow-wide 13- sprocket system. Despite being Campagnolo’s narrowest ever chain, it's also strong, light, durable and amazingly efficient. Technology: Narrow profile: lightweight, strong & efficient 1x13 Ekar profile: designed to interface perfectly with the Ekar Wide-narrow teeth design on the Ekar chainset Construction with different grades of steel & coatings: to create strong and durable links Unique ultrasound bath lubrication impregnation system: for long-life efficiency Includes Campagnolo C-Link for easier maintenance
