Hayes mount adaptor to mount a 74mm post mount Caliper (i.e. Hayes, Avid, etc) to a 51mm International Standard fork mount (i.e. Rockshox, Marzocchi, etc). Seperate mounts are available for forks with either a QR Axle or a Bolt Through 20mm Axle.
Please note Quick Release Axle forks require the thinner QR adaptor option, 20mm Bolt Through forks use a thicker mount.
Front 152mm - QR Fork, Front 152mm - 20mm Fork
Rated 5 out of 5 by Shane Nice little adapter
I replaced the front fork on my Specialized Hardrock disc pro 2010 (the old one broke).
Did not realise I needed one of these at the time. This simple to use adapter got me setup.

Rated 5 out of 5 by Anonymous What a part!! Simple, but it does the job. I never thought of just upgrading my bracket, costs a bit much for what it is, but considering i was going to pay £80 for a whole new system.. £12.99 for this and £25 for the disc saved me a lot!
