Campagnolo's EPS V4 External Interface is the beating heart of their EPS drivetrains. Not only does it take the electronic impulses and communicate them to the front and rear derailleur but thanks to its dual antennae internals, boasting both Bluetooth Low Energy and ANT+, it is capable of real time communication with a wide array of external devices ranging from smart phones to head units and more. This version is compatible with the latest V4 Campagnolo 12-speed EPS drivetrains and is suitable for external frame mounting, where internal routing is not possible.
Speed is nothing without control and the Campagnolo Direct Mount Brakes are proof of this concept. Lighter, stiffer and more aerodynamic than ever before, the Direct Mount Brakes are the perfect match for any 12-Speed Campagnolo drivetrain.Lighter, stiffer and more aerodynamic than dual pivot brakesDirect Mount design provides excellent braking power and modulationDesigned to accommodate larger volume tyres up to 28mm wideIncredibly light at just 347g per pairWith the Direct Mount Brakes, Campagnolo have created a powerful brake which is designed to work with up to 28mm tyres and are far more aerodynamic. The lever movement and bearings are completely new, this aids in modulation and increases smoothness. Braking power is also notably increased. Constructed from high quality forged aluminium the calipers save weight compared to dual pivot designs. Light, powerful and stunning to look at, the Campagnolo Direct Mount brakes are the perfect finishing touch to any Campagnolo equipped bike.
