Hayes Dominion A4 SRL Disc Brake

The Hayes Dominion A4 SRL Disc Brake combines motorsports-inspired engineering with trail-crushing performance, featuring a factory-tuned master cylinder that delivers the crispest bite point imaginable. Its cold-forged four-piston caliper and proprietary QuickBite² system provide consistent stopping power on rowdy terrain, giving you the confidence you need to tackle bigger, badder trails. This SRL version comes with a short reach lever ergonomically designed for smaller hands or short reach positioning.
