Tomorrow is better when you build on experience and success from the past to reach new heights. Hayes did just that with the limited-edition release of the Dominion A4 “Purple Hayes”. The purple colorway is a testament to the early days of mountain biking that saw Hayes bring technology to the world that forever changed our sport. The early editions of Hayes disc brakes were both groundbreaking and disruptive. To celebrate such a fantastic ride, a quarter century of moulding the definition of fantastic braking performance for mountain biking, Hayes are proud to introduce a limited run of the highest-performing brake to date, the Dominion A4, in a colorway that recalls perhaps the brand’s most iconic and visually striking model.
The A4 features the proprietary QuickBite system for fast and consistent burnish, coupled with the D-Series rotor to manage the heat with less braking noise.
Each set of Dominion brakes include both sintered (metallic) and semi-metallic brake pads in the box.
