    New bike derailleur adjustments

    Hi, I just bought a brand new road bike and i was told that i would probably need several derailleur adjustments in the first weeks.

    Is there a good guide i can use to do this myself ? Or I should bring it to the local shop every time ?

    Is it mostly the rear derailleur that will need adjustements ?

    Thank you

    Take it back to where you got it from. Then when the wheel eats the derailleur its their fault.

    The only adjustment you should need is due to cable stretch, probably only your rear derailleur. If you notice your shifting starts become sloppy tighten your cable adjuster a half turn.

    This. No reason an RD should require "several" adjustments. Their approach sounds like an original setup that is hit or miss.

    Brake cables "stretch" too, so you likely need to take up some slack in those cables as well, with a couple turns of the barrel adjusters.

    The "stretch" is really the housing and cable ends settling into the cable stops, which effectively shortens the entire cable, making it a bit slacker that it was as first. As this happens you need to take up that slack with the barrel adjusters to keep the original adjustments.

    Leave the limit screws alone and that shouldn't happen.
