    Avid BB5 Rear mounting.

    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...

    Those two holes are smaller than the adapter the BB5's came with and looks to be about an a half inch shorter than the avid adapter

    Sorry for how crappy it is. Only camera i had was my DSi.

    Any help?

    The photo is less than worthless... but it sounds like a 22mm Hayes chainstay mount. Adapters are available, but they won't fit smaller frames.

    Did you click the links I posted? You're completely not screwed. Click my links, buy the adapter, and mount your disc.

    You're probably right, but based on the really lousy photo, it's hard to tell what we're up against.

    I know what you were thinking of: the 22mm chainstay disc mount holes. But I adjusted the shadow level in Photoshop to see it. They are rack mount holes on the flat of the dropout. Ed's advice holds.
