Product information "Hayes Dominion A4 SFL Disc Brake RW"
Hayes Dominion A4 SFL Disc Brake RW
With the Dominion A4, Hayes has developed a brand new brake especially for trail, enduro, downhill and E-MTBs.
The Dominion 4's brake caliper has been completely redesigned and guarantees extreme braking power. There is a setting for the lever travel and the associated position of the master piston. The brake promises to be intuitive and to show a defined increase in braking force when the pads hit, which ensures a high level of predictability and control. Hayes is also particularly proud of the new bleeding system: the brake caliper is equipped with two bleeding openings, which are intended to ensure optimal ventilation of the system.
The Dominion's new lever is robust and the lever width can be adjusted without tools. The position of the brake calliper on the brake screw connection can be adjusted using a 2 mm grub screw. The screw connection takes place with the matchmaker technology from SRAM, but there is also an adapter for Shimano's I-Spec 2 attachment.
