Them two screws by the front derailleur...

...what do they do?

I can't find the specific front derailleur (Nexave) on the Shimano website, and don't really know what to search for...!

Basically I sometimes have trouble shifting up to the biggest ring on the front, and occasionally the cranks lock up when shifting back down to the middle one (3 to 2). So I figure these screws need adjusting, but I don't know which one, in which direction and by how much... :?

    Limit Screws...........same on all mechs - get ye off to sheldon brown if not sure.

    Be careful...... shifting up - if you over do it - you'll shift straight off,

    I take it you mean the derailleur limiting screws?

    Limit(ing) screws!

    Thank you :) Sometimes it's just knowing what the hell something is called in order to find help...

    Hrm, looking at the pages about it (cheers guys) it doesn't look like these screws are going to help my occasional lock-ups :(

    Could also be your cable tension needs a bit of adjustment. New gear/brake cables are known to stretch a bit (some come pre-stretched) with use. There'll be a barrel adjuster to tune the tension somewhere: possibly where the cable routes onto the frame down tube or on the shifter itself. Fettle away :)

    Hrm, maybe. Been doing it on and off since day 1 though, and I mentioned it when I had the first service but was unable to tell them exactly when it happened, so I guess it passed unfixed.

    Hrm!

    Oh well, one step at a time, have trimmed an inch off either end of my handlebars tonight so maybe this can be done another night....
