Need a reasonable, sealed BB for 75's

hamster Going to resurrect this topic.
I have the crankset at the bottom of this page, the RD2.

They say this gives a chainline of 45mm. I've got Goldtec hubs with an EAI cog, which should give a chainline slightly more than 45mm. However my chainline is out by more than slightly (at least a couple of mm). Who's wrong?
The spindle is 103mm. Am I right in thinking that a new bb with a spindle about 107 (ie the miche mentioned above) should fix the problem?

Cheers for that
Dan

i've got the same combo, miraculously a campy centaur 111mm BB is spot on! NOTE: i didn't plan it this way.
