    Nice picture of the rear derailer! It would be useful to have a description of how it was used by the rider.
    Thanks

    I second that about the rear. Looks almost single speed like and sweet. Is this just a featured bike or is it your?

    You ride it much if it is.

  4. The Cambio Corsa or “race changer” derailleur represents Tullio Campagnolo’s first attempt at designing a gear shifting device. The dual lever and rod design was popular from 1940-1951 when parallelogram designs finally took over. The top lever allowed riders to loosen and tighten the rear quick release. The bottom lever allowed riders to move a cage the chain passes through up and down several freewheeled gears.

    Upshifting required riders loosen the quick release, start backpedaling, push the cage lever inward to the desired higher gear, and tighten the quick release. Downshifting required riders loosen the quick release, start backpedaling, pull the cage lever outward to the desired lower gear, and tighten the quick release.

    The lengthening and shortening of the direct chainline forces the unreleased rear wheel to slide up and down slotted dropouts on the frame. Not entirely effortless but a simple design that allowed racers to continue shifting despite inclement weather conditions that frequently hampered early Simplex dual pulley designs.

    My husband and I went bike shopping a few weeks ago (haven’t owned a bike in years) and we noticed how ugly bikes are nowadays. We hardly saw any “normal” looking bikes like the ones in your pictures. They try to make the bikes all fancy-looking I guess but they look kind of weird. Maybe it’s just in my parts because I can see from your pictures that there really are normal looking bikes out there somewhere.
