    chain rings 7 speed chain

    I'm needing to change the crank set on my bike from 175 crank arm triple. Its a 7 speed cassette. I need a 170 crank arm. Can I use a 9 speed compact crank set with a 7 speed chain width? Is there going to be any other probs to look for?
    Thanks,
    Mark

    If the nine speed wont work, does anyone know where I can find a 170mm shimano crank set for triple chain rings? The crank I have now is a 105 FC 1056/1057. 1995 model 8 spline interface.

    The issue I may see is whether the chainring offset is proper on a triple. Give Shimano tech support a call and see what they say.
