  1. hello, I posted a while back about the derailler hitting the spokes. I took it to the shop and the guy set it looked okay, but the low end screw was out pretty far. I believe he adjusted the stop and reset the screw. He also put grease on the cable. Everything seems to be good as far as the derailler hitting the spokes, but now the bike isn't shifting very well. Sometimes it doesn't shift right away and it's fairly loud and hard when it does shift. This seems to happen the most in the middle gears. I have a maintance book that says to turn the barrel adjuster counterclockwise until it shifts properly. I figured I would check here perform I make any adjustments. Thanks for the help.

  2. Up, down or both directions?

    It seems to be when I'm shifting up from a small cog to a bigger one.

    Muck with the barrel adjuster slightly, turning it counterclockwise (outward) a quarter turn. Most likely there is a slight bit of excess cable slack.

    Sounds like cable drag/housing compression issue.
    I suggest a new, clean cable installed in new high quality "compressionless" Shift Cable housing with new metal ferrules on the ends. The housing and cable should be treated as the manufacturer suggest. Clean flat housing ends properly seated into metal ferrules helps. Sometimes greasing the cable is the wrong thing to do as it adds drag and draws grit inside the housing. Some housing is already lined with very low drag material that really isn't helped with grease.
    Sometimes the bare cable routed under the bottom bracket guide needs cleaning and a light amount of lube in the guide "slot".
