I'm interested in cold spacing my frame (130mm rear Lemond Poprad disc) to accomodate 135 mm hubs. I've read about the procedure, per Sheldon Brown, but what's unclear to me is how I can keep my disc tabs aligned, relative to the rotor.
There is a certain about of rotational "flex" in the mounting system for the Avid BB7 calipers so this might mitigate any misalignment issues, but I am not sure.
(1) Any insights into this?
(2) Should I cold space to 132.5m so I can run both 130mm and 135mm?
(3) I am running road double cranks. If I went to 135 mm rear, will this mess up my chainline? Or will this change be minor? I am not sure what a 2.5 mm deviation from the stock chainline would do for my shifting.
