Description

Expanding on our award-winning Dominion A4, Dominion A2, targets Cross Country and Trail riders.

Dominion A2 features a two-piston caliper. Dominion A2 includes all the performance from the Dominion A4, utilizing a compact, two-piston caliper.

Dominion's master cylinder is factory tuned for the shortest dead stroke possible and a crisp bite point. The Dominion A2 caliper utilizes four pistons in the most structurally rigid design possible. It features a cold-forged caliper and KingPin structural pad retention bolt that increases stiffness.

With a motorsports-inspired Two-Stroke dual port bleed system, industry-leading DOT 5.1 fluid and Kevlar hose, the hydraulic system is engineered for ultimate performance across all temperatures and easy maintenance.

Dominion A2 features the proprietary QuickBite² system for fast and consistent burnish, coupled with our D-Series rotor to manage the heat with less braking noise.

Dominion In The News

"The Dominion brake is a winner in every sense.. If you are in search of a good brake, start with this one"

"I find myself recommending these to everyone that sees them on the trail."

The Lost Co Logo

"Overall, the Hayes Dominion’s performance was very impressive indeed, descent after descent we encountered nothing but consistent and precise braking."

Enduro MTB Magazine

"if you’re chasing the hand and arm fatigue gremlins but haven’t yet experimented with more powerful, easier to use brakes, consider this an endorsement from a weak-handed man who’s now less sore at the bottom of every descent."

Downcountry dominions

I got these when my XTs crapped out last year. They are amazing brakes. The sealed bearing levers are the smoothest you will find and the modulation is great. They are on my XC race bike, heavier than I would have preferred but they have all the power I could ever need and modulate well enough that I can get every last drop of traction out of my weight weenie XC tires. Someday I will hav Dominions on all of my bikes.

Truly amazing brakes

The Dominion A2s are simply beautiful brakes. Not just beautiful to look at. But more importantly, beautiful to use. Smooth. Powerful. Adjustable. And paired with D-Series rotors, you can leave the orchestra behind, because you won't hear a chirp, squeal, or whine from these trail angels. Really, these are great brakes. When it's time to upgrade your inferior OE spec brakes, or time to build your dream bike, you owe it to yourself to take a hard look at the Dominions.

BEST BRAKE EVER!!!!

really. its is. I have the standard lever A2, and my wife is running the SFL and they feel great and have not needed to bleed them since install one year ago.

Hide yo shimano's, hide yo SRAM, Dominions are coming!
