    anyone have a spare (hallowtech) crank arm lying around.
    The threads on the spindle are gone and it keeps coming lose.

    Black would be ideal.

    An engineering works might be able to drill out current threads and put heli coils in... Not hard or expensive

    It's the end where it joins the shaft coming from the other crank as oppose to the pedals . The hole would be to big if I retreaded it as its completely smooth

    Hi thanks for getting back to me about the crank, how much are you looking for? I work in town and live in south Dublin.
    Where abouts are you based? I Persume that it'll fit a 5750 hallowtech

    TBH that's a bit more than I was hoping.
    I can get a whole setup new for 110 which includes chainrings.

    I understand it's ultegra but I am good with something lower
