    I just got a new bike and know very little about maintenance. I rode
    it for about half an hour on a mag-trainer and it worked very well.
    Today, while riding, after about five minutes, the front derailleur
    shift lever just started loosening and causing downshifting. I can't
    figure out how or why the lever is loose, it has a plastic nut that I
    can finger-tighten, but am afraid to put too much torque on it for fear
    of breaking it. I can pull the cable with my finger and cause the
    lever to loosen and downshift. The levers are mounted to the downtube
    and are shimano SIS the model is SL-SY20A

    Thanks for your help
