Adapts frames with 22mm "Hayes" mounts on the seatstays to to accept international standard 51mm calipers. Will not work with chainstay mounts.

so does/did hayes make a 22mm caliper?? was this something that was made in the past and no longer?

I'm connected to this crazy thing known as "the Internet" (lots of info on that thing, if you're willing and able to look) so let me help you.

Within th first six results:

"22mm Hayes direct mount this mount is becoming obsolete. This mount was typically found on rear chainstays only. It consists of 2 holes drilled vertically into a reinforced section of the chainstay, the holes are threaded and approximately 22mm apart. Even though there are adapters that mount a IS caliper to the 22mm direct mount, most current calipers will not fit due to lack of room under the seat stay."

thanks

I have a hayes 22mm caliper I found off Ebay. It's been the only one I've seen even after working years and years in a bike shop. Try to find it on Ebay, or hit up your local (former) schwinn dealers as the high end frames had 22mm mounts for a while.
