Since I only have a B.A. in History I don't feel the pressing need to take the moral high ground. There is no point in my assuming the moniker of "Historian."

I'm not above anything

Back to threading -it is fascinating stuff.

The question I ask is why did the Taiwanese continue to produce bikes with 26tpi threading when they scaled up production for the early Raleigh-USA bikes? Did they have a big stock of English-made cups they wanted to use up? 24tpi cups were readily available as that is what everone else was using in the Asian factories. I would have thought it would have been a good time to make the transition. Tooling up for 26tpi bb's and forks must have been actually harder than using the standard of the area, but I've worked on these bikes and they still have 26tpi threads for some reason. I can't believe they shipped the tooling all the way from Nottingham to set up their factories. Did they? Or did they spend extra money to make new machines to conform to a backwards standard? Why?
