From my experience with Shimano outboard bearings, I found that grit easily got between the arms and bearing covers, making clicking and/or grinding noises. I haven't heard anything like that from my Campy outboard bearings yet, but that's not to say it won't happen.

Personally, I really like square taper BBs because they seem to spin nicer, and they're easy to remove, clean, etc.. Just like anything else, though, you get what you pay for - OEM RPM BBs are nothing compared to good Shimano or Campy BBs.

While I was coming back from Home Hardware this morning, I got a look at someone riding Surly Cross Check. Those are much nicer bikes in person, IMHO. Wonder how heavy they are.

using this id until my ban is lifted... ssshhh
