Tomorrow is better when you build on experience and success from the past to reach new heights. We did just that with a limited-edition release of the Hayes 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 molding the definition of fantastic braking performance for mountain biking, we 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.
