Anecodotal account of "Precesion" at worK:

I'm not sure if this is Murphy's Law or just karma at work, but a funny thing happen while doing a shake down ride last evening on a recently acquired, second hand Calfee single bike that had a bottom bracket with Italian threading. It's probably been 15 years since I had a bike with an Italian threaded bottom bracket.

Whilst out on my ride and about 12 miles from home I noticed the front derailleur wouldn't shift the chain into the big chain ring. A quick check confirmed the cable didn't slip in the pinch bolt, the shifter was working fine, the cable was not bound-up, and the derailleur and derailleur stops were where they should have been. Hmmmm. That's odd. Further inspection on a hunch revealed that the bottom bracket cups and cartridge bearing spindle assembly had backed itself out of the bottom bracket shell as a unit: not at all an uncommon problem with Italian threaded bottom brackets. Not having a crank puller or Campy bottom bracket tool in my pocket, it became a challenge to see if I could get home before I was REALLY in trouble. Thankfully, I made it but by the time I hit the drive way the left-hand crank was rubbing against the left side of the bottom bracket shell and, if there was any doubt, carbon is tougher than aluminum.

Note to self: Remember to use Loctite 242 before torquing the fixing cup on Italian threaded bottom brackets.
