Bici II Hub Failure

After taking a few weeks off riding to work, I pushed a little too hard and broke my hub.  Luckily I still had the old wheel and hadn't yet switched to the STI shifters, so it was a quick fix to put the old one back on.

Today I pulled apart the 7 speed wheel and I assessed the damage.  It was incredibly hard to get the axle out - when the hub broke, it must have forced the bearings to really tighten.  So much so that it smashed the bearing race:

It's hard to see from the photo but there are also imprints from the ball bearings themselves.  Yikes.

This hub is toast - I've replaced it with an old Deore one and will avoid using nutted axles on this bike in the future.
