    Using a Front Derailleur Shifter on the Rear Derailleur

    I converted to a single chain ring on the front and am getting a new frame to put together a second bike. Shifters are pretty expensive, so I was thinking about getting just a simple set of drop bar brake levers, putting one on each bike and taking the front derailleur shifter (old shimano 105) on the new bike to work a nine speed shimano 105 rear derailleur.

    Is this possible?

    In a word, No.

    The front shift lever only has 2 or three positions for double or triple chainrings. Not only aren't there enough clicks for a 9s RD, they're not spaced correctly either. Even if you had Campy shifters, with a non-indexed micro-ratchet front, and wanted to shift non-index you'd still be out of luck, since the increments are too course to use for friction shifting.

    Thanks very much, I thought it was a dead end, but wanted to check.
