Dominion A2 Brake
by Hayes
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 A4 caliper utilizes two Ø24mm 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. Also available in SRL (Short Reach Lever) - ergonomically designed for the smaller hand or short reach level positioning.
