Hayes Disc Brake Adapter Post Mount Forks
Hayes Post Mount Disc Brake Adapters allow you mount 74mm disc brake calipers on forks with 74mm tabs when using larger size rotors. These 2 specific adapters are for either 7 inch or 8 inch rotors. If you intend to use your 74mm style caliper with a 6 inch rotor it will mount directly to the fork without any adapter.
Everything lined up perfect
bolted up with ease, quality machined product
This matched up with the post mounts on my fox fork and rockshox perfectly. It was also nice that it had e grade labels telling which side goes up so installation was full proof.
