Front Mech

    Oldlegs Frogs are people too.

    I have recently replaced my groupset (Sora to 105) and the whole lot went fine apart from the front mech. I cannot get the (bad word) thing to work without rubbing when on the small chainring (double). The derailleur is fitted right (parrellel to the chain, about 2 mm off the chainring), limit screws set to the Shimano instructions and the front gear change works well. I am coming round to the view that front mechs are the work of the devil :blush:
    Any help much appreciated

    Hi OL
    The park website has a good adjustment guide

    even when well adjusted you can still get some rub though. :blush:
  3. The best thing about the old style friction levers is that you can make tiny adjustments to the mechs while riding simply by moving the levers. Indexing is useful but it can be a bugger to set up properly - like Starseven says, it might rub no matter what you do to it.

    I symapthise on this one. Thought I had mine set up perfectly at the weekend but it threw the chain off the high side this morning half way to work :blush:

    angle it ever so slightly (about 1º) out at the rear. :blush:

    Finally got there :blush: - more by luck than judgement though.

    Front changers are the work of the devil, more so with indexing, and even more so with triples. :blush:
