Okay. One more question.

I received the 107 bb that I ordered a while back, and finally had a chance to try it last night. With it, I've got about 0.5mm of clearance between the small ring and the chain stay, which I am definitely not comfortable with. So, I have two options. Buy a new 110, or put a spacer on the 107.

I probably would just go the spacer route, except I ran into another quirk that I haven't had to deal with before. If I space the drive side out 1.5mm, then the non-drive side cup will recess into the bb shell another 1.5mm. This will start to expose a few threads of the bb shell. This would then be a collection point for water, and corrosion. This must be a common issue with spacing shimano cartridge bb's, but I can't find any reference to it online. Thoughts?

Thanks,
- Jeff
