Hayes Dominion A4 - Black

Hayes Dominion A4 - Black

Introducing the all-new, Stealth Dominion, our award-winning Hayes Dominion A4 brakes are back – adding even more ways for you to stop!

Dominion's master cylinder is factory tuned for the shortest dead stroke possible and a crisp bite point. The Dominion A4 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 A4 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 DETAIL

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)
