Actually the slant parallelogram rear derailleur was invented in 1964!Originally Posted by oldbobcat
I like modern bikes, but I'd say the most important technological developments since 1984 have to be
- clip-in pedals and shoes that fit
- 130 mm freehubs (and 9-, 10-, and 11-speed cassettes)
- the slant-parallelogram rear derailleur
And despite the complexity, modern mechanical shifting systems are pretty darned reliable, if not exactly maintainable.
Also toe clips were not bad at all if the person had the right shoes with the right cleats they worked as well as clip-in just a bit more finicky getting into the pedals, but for years after clip-in came out track bikes used nothing but toe clips because they were stronger and the track racers would pull off of clip-in, it still happens today, I saw that in a video of last years TDF where one rider pulled out of his. I use both systems and I do like clip-in but only because ease of entry is so much faster and less fumbling around, otherwise they're virtually the same.
All those extra gears is ok, it does keep you closer to your ideal cadence but it does shorten the life of the components, thinner gears and chains now last no more than about a third as long as the older wider gears and chains, innovation? maybe, but at a cost.
I think the greatest innovation in components was SIS shifting, it shifts far faster than STI or Ergo. I have in my small stable friction, SIS, STI, and Ergo, and SIS has them all beat; dare I say, I find that my Suntour Superbe shifts just as fast as STI or Ergo, only difference is there is a greater degree of missing a gear with friction then with STI or Ergo, but if you know how to use friction real well that degree is fairly limited.
Of course all the above is just my opinion...except the invention of the slant parallelogram, that is fact, and it was invented by Suntour; and gears and chains today don't last anywhere near as long as the early 80's stuff, more facts.
