Expanding on our award-winning Dominion A4. Our newest brake, 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. With the SFL option, the Dominion is the ideal brake option for any rider with smaller hands. Hayes product development team set out to design a brake system specifically designed for a smaller ergonomic profile.

Dominion SFL maintains all the power and feel of our proven Dominion A4, and accomplishes this using a specifically designed smaller and narrower brake lever. Dominion SFL can be used in conjunction with either our Dominion A2 two-piston caliper or our Dominion A4 four-piston caliper. With optional lever sizes and two caliper choices, Dominion from Hayes Disc Brake now offers a brake that's ideal for your application.

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.

Available in SFL (Small Finger Lever) - ergonomically tailored for the smaller hand.

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."

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.

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!
