  1. Yesterday I replaced my left side thumb shifter return spring. Today
    after my first ride I noticed the clicks weren't crisp and snappy when
    shifting between chainrings. The FD trim wouldn't stay trimmed while in
    the big ring and the FD would ever so slowly creep inward eventuatlly
    causing chain rub and a down shift to the middle ring all on its own.
    My question is, should I have replaced the G-springs while I had it
    apart yesterday or did I miss something else in the rebuild process?

    G springs and maybe a cracked spring carrier..also if the lever is 1998
    or later, that flat watch type spring needs to be installed correctly.

    Thanks Peter. I thought something was funny the first time I put it all
    back together when the big flat spring didn't want to stay hooked in
    place. Took it apart again and replaced the G-springs and figured out
    how to properly install the big flat spring. Should work.
