Avid BB7 and Avid Mountain Ball Bearing Disc Brakes

Hi All,

I need your collective wisdom. Is there a difference between the Avid
BB7 and the Avid Mountain Ball Bearing disc brakes?

I bought a set (front and rear) from an eBay seller advertised as 2005
BB7s. The brakes I got have Mountain Ball Bearing on the box and 2002
Mountain Ball Bearing Disc brake installation guidelines enclosed (links to
various PDFs below). The rotors are 160mm.

It's unclear from the Avid website if there's a difference. I want to
know if I've been diddled. It looks to me like there's no difference in the
caliper. The BB7 instructions only have drawings, so it's hard to tell. I'm
thinking there may be a caliper difference - does the "7" refer to a 7 inch
rotor?

It's quite common for companies to produce a single manual for a whole
product family (eg the BB range). The product family may well be know
as Avid Mountain ball bearing disc brake.

The manual being from 2002 is a bit more of a worry. Right now I'd be
weighing everything to see how it compares to the weights listed on
http://weightweenies.starbike.com/listings.php, but I'm just a weight
weenie :P.
