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...

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

Any help?

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.

ok heres 2 more pics that might help better. This first one is the Mounting holes in comparison with the bracket they gave me.





Ive done a little re-search and it looks like i need somthing like this.




Im so confused. I hate brakes right now. Imma use my foot.
