Can anyone tell me how far apart the cups should be spaced on a Shimano 83mm BB?
For example, the 73mm version has to be spaced 75.5mm, which is why a 73mm shell needs one 2.5mm spacer, a 68 needs 3 spacers etc. The 83mm BB came with 3 spacers but I find it hard to believe the total spacing has to add up to 90.5mm...
