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
LOW INPUT – HIGH FIDELITY (LOFI)
Low effort system with predictable, progressive ramp up and a crisp bite point.
LOADED WITH TECH
Reduced Friction – A featherlight lever feel is acheived through a combination of an added glide ring on the piston and sealed ball bearings at the lever blade pivot
SRL – Our Stable Rate Link delivers a consistent lever ratio regardless of reach
Precise Engagement – Each Dominion is factory set to have the lowest dead stroke possible and a crisp bite point.
Built to last – Metal pistons are used to ensure that no matter the terrain or temperature your brake will continue to perform as it did on the first ride
Adjustable Reach – Adjust your lever reach with ease while on the trail thanks to an intuive adjustment knob design
MODAL RESONANCE CANCELLATION (MRC)
FEA-optimized modal shapes of D-Series rotors are intentionally designed to oppose those of Semi-Met T106 and Sintered T100 pads, canceling out noise and vibration.
