    Need help finding adapter.

    Hi, I just recently bought a set off Avid bb5's and im having an issue finding out what size adapter i need to mount the rear caliper.

    I have a 1998 A50r frame. Im not sure if the mounting holes are international size or what. Heres a picture...

    Link's not coming up.

    You buy the Avid's used? All the new ones come with adapters. Rears use a standard IS mount and are specific to the diameter of the rotor you're running.

    Basically one of these:

    You're probably using a 160mm rear but I'm speculating there...

    Way too vague to give a useful answer -- but in 1998, the Hayes 22mm chainstay mounting was common... and entirely different from the 51mm IS or 74mm post mount stantards of today.

    A viewable photo or more info would be helpful.

    Sorry. Heres the picture again. When i was at the bike shop they told me i could with those holes, I just would have to find an adapter



    They are smaller holes than the ones with the adapter that came with. And have a shorter spread inbetween. And yes i am using the 160mm rotors.
