Hi folks.
Had the new bike about 2 months now, still a dream, but, since i bought it off the net, no free six week service.
Everything else seems fine, except the rear mech has started undershifting.
Is this cable stretch, or is there a possibility of another problem?

More to the point, does anyone know how to sort this? Do i use the mech stop screws, or is it a case of resetting the mech up?

All advice greatly receaved. Cheers in advance.

Oh, and i have tried park tools, but don't really know where to start with the issue. :?

    undershifting?

    i guess you mean that you are not getting the correct gear?

    cable stretch turn the adjusters.

    How toos on Park tools are good.

    To clarify when i say undershift, i mean that i shift, and nothing happens, i need to push the leaver a bit more to engage the gear... If that makes any sense what so ever.

    So can i just tighten it using the adjusters on the shifters?
