I had same problem with my Bob jackson. Nuovo Record cranks and centaur 111 BB. Filed the shoulders down, but then found that the bolts caught anyway. So spaced the cup accross about 1.5 - 2 mm (width of a lockring) as I wasn't about to spend another £40 on a BB if I could avoid it. Works fine now is perfectly spaced on both sides.

Did you space the cup with a lockring. Can you get thinner spacers for this. I've got pistas on a 109 BB, but when i put power down, the corner of the spider shaves the paint on the chainstay. However, there is not much thread to play with on the non drive side cup as is, so i'd only be able to space it over maybe half a mm. Any ideas, other than filing the back edges of the spider a little, which i'd rather avoid doing if i can.
