  1. I have a mountain bike that i have had for a few years. And i was trying to adjust the gears on it.
    I got the gears to change on the rear sprokets but they are still a little sluggish and the front
    gears i cant change at all. I checked the cable on it but it doesn't seem to be broken. Are there
    any other adjustments i'm missing? Thanks

    Change the inner wires and housing thru out. Cheap, easy way to improve overall shifting
    performance. If can't figure it out-go to a bike shop, it's what they
    do...

    After rereading your OPost, I have nothing positive to offer. You haven't seen the usual helpful
    advice from a generally helpful group. Your symptoms are so nebulous as to be reasonably acribed to
    anything and everything, especially when you assert the control cables are functional.

    To get a derailleur gear system running properly, my advice is: Ensure the chain is not worn out and
    that it is neither dry and rusting nor caked with a grunge of oil and dirt. Ensure rear hub and
    crank bearings are not loose. Ensure the chainrings are not bent and that there is no foreign
    material occluding the teeth, front and rear. Ensure the rear changer is aligned straight to the
    bicycle in both planes and that the rollers ( or body for that matter) are not sloppy with wear.
    Sight the chainline so you know it's not grossly askew.

    If that all looks acceptable, shift the rear changer with your thumb before connecting the control
    wire. Make darned sure you cannot push that cage past low gear into the spokes. When you push to the
    second highest gear and let go, the changer should drop smartly to high.

    If that all looks good, ensure the control wire is not kinked or frayed. Ensure the casing is not
    damaged and sits squarely in its seats with the proper ferrules. Smear a light lubricant on the wire
    where it runs inside casing or over nylon guides. Lubricate the anchor bolt and adjuster threads.
    Now you can connect the wire and shift one click. The chain should be on the second cog. Beware a
    loose wire such that the first click does nothing and the second click makes the first shift, That's
    a common error.

    For fronts, get the cage straight to the chainrings and 2mm above them at the closest point in its
    travel. Shift the rear to low and set the front limit such that the chain just clears the inside of
    the cage. Now shift the rear to high and make sure the high limit will let the cage clear the chain
    at the outermost point. Lubricate the anchor bolt and connect the wire. Ensure the derailleur can
    span the entire range and that the chain will not travel past high or low when the shift is
    aggressive.

    Could you be a bit more specific?

    Finally someone who does care about the posters in NG's!

    Ok let me see if i can be as specific as i can. As i said in my last post I did get the gears to
    change on the rear sprokets but it shifts a little sluggish. But What i should have said is they
    sometimes do seem to have a delay while shifting. Now the front grears will not change at all.
    But now that you have explained to me What the adjustments should be on the front derailer I
    will look into that. Ok now heres another thing i haven't been able to figure out. When changed
    into a lower gear on the rear i hear the chain barely rubbing on the cage in the front. But when
    i try to shift the front gears the rubbing stops but it doesn't shift. Thank you for the indepth
    explanations in your last post to me!

    I stil do not know what kind of gear system we are talking about. A normal (classic, G/S, Ergo)
    front shifter should be trimmed after a few rear shifts as the chain angle changes. With an index
    front shifter, the cage is usually much wider than would otherwise be necessary. Even those
    systems (Ultegra, etc) have recently begun incorporating a trim feature because it's nearly
    impossible to adjust without it. So, do you have an index front shifter? If so, position of the
    cage (in three dimensions) and maybe even the shape of the cage ( yes, bend it) becomes critical.
    Chain rubbing front cage in some gear combinations, while avoidable and not "normal", is quite
    common to those systems.

    Front changer will not change at all? Did you clamp an accessory over the gear wire?

    If your rear shifting is sluggish, go back through the checklist posted earlier. One or more of
    those items is not optimal ( derailleur tab alignment? chain wear?)
