Introducing the all-new, Stealth Dominion, the 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.
