Thanks all for the info! I did get the BB out and it looks like the one you're showing, stan. It's at work right now so I can't compare the text, though. Assuming it's that size, would this UN54 work? http://www.rei.com/product/753545 (I am also going to look into the new-old-stock suntour).

About the chain, leecycle, good question - what is the proper width? It's possible that it's not right, I wondered that. Where do I measure the width?

Thanks
Nick
