Hayes Dominion A4 MTB Disc Brake CaliperReady for long days on the trails, this mountain bike (MTB) hydraulic disc brake caliper is kitted out with four pistons in a structurally rigid design for maximum durability. Featuring a cold-forged aluminium construction and a KingPin structural pad retention bolt, it delivers increased stiffness and dependability as you carve your way around the mountain. Another highlight is it’s compatible with the A2 brake lever, which means you can upgrade your existing A2 caliper to this one and still use the same brake lever.
