Hayes Dominion A2 Stealth SFL disc brake black/gray

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.

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.
