I agree about the relentless and sometimes baffling march of "progress". My bike mechanical world has stopped with Ti and steel frames, English threaded bottom brackets, caliper rim brakes, aluminum rims, straight steerers, threadless headsets and 3x10-speed mechanical drivetrains. So far I've avoided carbon frames, carbon rims, disc brakes, tapered steerers, 11, 12 and 13(?)-speed cassettes, 1 x anything drivetrains, a whole spectrum of different bottom bracket "standards", and electronic shifting. My loss I guess.
