If I'm not mistaken, there is an extensive discussion about seamless shifting buried in the archives, though I'm not certain it's relevant. Or even sensible. :lol:

Heh, Heh. If you find that thread you will be blessed with multiple interpretations of the word "seamless" and several pages of illuminating discussion theron.

It's largely a crank arguing semantics from a position of engineering non-authority, but (and this is an internet Pro Tip), scroll past the troll and there's some good stuff from good authority.
