The AD-PMR adapter would not work on my frame - I've got a 2001ish Trek 8000. A2Z would have taken it back had I not barely trimmed on it w/ a grinder. I ended up going w/ the universal mount (DM-UNI) and it works great. I still have the AD-PMR it if you want to try it. Try it, send me some bucks if it works. If not, send it back and I can throw it on ebay - they're sell for around $20. Thanks.

I havn't seen the AD-PMR adapter. Got pics? I saw the DM-UNI on a GT like mine online but with no review about it. Can you post pics of yours? And what brakes did you end up with on the adapter?

The AD-PMR adapter is for a 22mm mount like the one that can be seen in the picture below:

Sandwich the dropout and remove the skewer to r&r the wheel.

Follow cobba's link. Again, the red one did not work for me while the UNI worked like a charm.

A2Z DM-UNI, it might be a bit of a problem to attach if the drop outs aren't flat.



The A2Z AD-PMR would work fine if the 22mm attachment point was on the seat stay instead of the chain stay.

Another 22mm mount, I don't know well it'd work & whether there wold be any flex with it:

This is what I found....Online Bike pics.jpgThat is on a GT Zaskar like mine, but I was going to use some Avid BB7's on it.

AD-PMR on a 90s Trek ZX 7000 21" with Shimano BR 455 hydraulic brake

I encountered the same problem with these adapters, the seatstay was in the way and this is on a large frame bike, I'd read this was more of a problem on small frames. I had to grind down the rear outer edge of both the 51mm standard mount and also some metal on the brake unit itself. I also had to file the rotor mounts so the rotor sat a little further into the wheel. This was fiddly but by no means difficult. I haven't weakened the parts but they haven't much resale value, but these are unwanted parts.
