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.
I had to buy this product since the lame Avid interface uses a single bolt for both post and caliper mount. The long bolt worked its way out and I didn't have a long one to replace it with. This setup seems much more secure, though it adds a slight amount of weight through double bolts, even if they are shorter than the Avids.
super easy to install. these adapters will work perfectly on both the fork or the rear frame of the bike if it has post mounts
A necessary evil when upgrading front rotors. Gets the job done and helps get me out of the garage and back on the trail.
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.
