BB5 to BB7

Can I replace the Avid bb5's on my 2008 Tour with bb7's? If so, is it a simple remove and replace, or there additional steps that need to be taken?

Yes.

Although it does require some mechanical ability. Then Adjustment.

When converting from avid bb5 to bb7, should I also go with the 185mm rotor? Does the bb7 install to the same mount that the bb5 uses? Would a 185 rotor mount to the same interface as the 160 mm rotor? I have fenders on my bike and the fender struts also act as spacers for the brake mounts. Would this stay the same or are there different shims/spacers required for bb7?

I want to make sure I have all the parts, accessories and spacers before I start. We've only got one LBS here and they've never seen a "contraption" like mine. What else do I need to know that I wasn't smart enough to ask?
Thanks.

Thanks.

OK. Just one more question, I think...If I decide to take my fenders off, what size spacer do I need to use to position the brake mounts properly to line up with the rotor? Is the spacer a standard part that I can get from you?
Thanx

We space it out with 2 M6 washers. You can get it from us.
