The best just got better. The limited-edition Hayes Dominion T4 packs the power, sensitivity, and reliability the Dominion family is known for into its lightest chassis yet. Featuring a Reynolds designed and in-house produced carbon-fiber lever, titanium hardware, composite reservoir cover, pads with aluminum backing plates, and precise weight-reducing machining.
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.
Crosshair Caliper Alignment screws allow for quick and accurate setup.
King Pin pad retention bolt adds strength.
2-Stroke dual port bleed system for maximum bleed integrity.
