Well, it's got me really nervous. I'm about to deal with the BB, and I'm afraid that if there's a problem with it or tiny parts, I won't be able to find the right replacements, since I have a long derailleur on my 600 EX grupo. I'm not a stickler for keeping it original, but my instructors keep telling me to stockpile parts while I can, and to save the bad parts in case I'm ever desperate or the new parts don't work the way they're supposed to.

I broke a chain whip on my precious uniglide touring cassette and just about had a heart attack. I wish I would have used an cheap Magna to do my learning on.
