Prepared for intense mountain bike rides, this disc brake features a hard-wearing aluminium construction. This makes it more than capable of handling all the abuse that's associated with all-day epics in the mountains. Coming equipped sealed cartridge bearings, this disc brake offers incredibly smooth operation while also remaining protected from corrosion. This enables you to enjoy its superior strength and control in all-weather conditions, without worrying about the bearings being damaged.
Engineered for ease of use, this MTB disc brake is kitted out with an adjustable lever reach. This allows you to easily fine-tune the distance between your handlebar and the lever for a more customised braking feel. As a result, you'll benefit from its brake lever which perfectly matches your hand size, riding preferences and the terrain conditions. This makes the Hayes Dominion A4 Disc Brake an ideal choice of upgrade for riders who want greater flexibility on the most demanding MTB trails.
