Cassette is actually a 11-30, not 11-32
Pros: Road this bike for 13 years, totally solid, still doing the job, minimal repairs.
Comments: The cassette installed from the factory is actually a 11-30 8 speed, not an 11-32, as I found out to my peril when I stupidly ordered an 11-32 to replace the cassette, assuming the information was correct here, rather than just counting the teeth on my old cassette! :D

BB size is incorrect
Pros: I turned it into a commuter bike and have ridden it consistently since 1998. Components have been flawless. I haven't changed anything except the tires.
Cons: Nothing really, it suits my needs.
Comments: I recently noticed the BB was wiggling, so I decided it was time to replace some parts. I broke a spoke on the rear wheel a year or two ago, but only recently replaced it. Other than that, I haven't had to replace any of the parts. I found this site while I was trying to determine the BB size. The BB that was in the frame is a specialized model that looks exactly like a square taper shimano cartridge style BB. It had a 73 marked on it, but no spindle length. This site, and other comments I found online, state that the BB shell is 68mm. That is incorrect. I measured the shell and the BB spindle and came out with 73mm x 110mm. I hope this helps others out, but it is easy to just measure with some calipers.
