(Chorus and up) but that requires a more complex axle design, is more

I obviously have some mechanical skills.

Yeehaw!

I think it's more about tool ownership. The various BB standards are part of a giant conspiracy between Park Tools and certain other shadowy interests -- perhaps the Yakuza or Mafia. If you have a BB30 frame and a Campy crank, you can go whole-hog and spend over $200 in tools for the Park CBP3, CBP5 and a BBP-1 or a headset press. Throw in the $700-1000 Super Record crank, and you're starting to talk some money.

One can do it from the other side of the fence, as it were. Buy only
bicycles that have bottom brackets that fit the tools you already have
:-)

As an aside, there are companies making bicycle tools that sell for
far less than Park Tools. http://www.framebuilding.com/ for example,
lists three categories, "Economy Tools", "Best Quality Tools" and
"Other Tools" :-)

JB runs GT, we ride World Class middle class 8 speed

GT parts probably cost 5-7X WC.

In Portland there would be a class distinction, yes ?

Or....is there a social cycle hysteria for keeping up with the Hatch's ?

Gotta wear a jersey ?

I only own the special Campy BB cup tool. I used alternate methods to
remove and replace the cartridge bearings on each half shaft.
