    Derailer swing

    OK I got a new front derailer for a commutor bike I'm building. At the time I guess I must have brain farted and I didn't pay attention to the way the old derailer puled or swung. If I'm having my LBS run all new shift and brake cables will the pull direction matter? I don't have the old FD anymore so I can't give any usefull info on it, but I do belive it was a top pull top swing. The FD I'm trying to use is a Deore LX FD-M570. Any input would be great. Thanks

    The pull direction refers to wether the cable follows down tube and goes under the bottom bottom bracket (bottom pull) or follows the top tube,behind seat, then to derailer (top pull). Can probably make the "wrong one" work but it will take more labor/parts.

    Pull the lever that connects the cable on the derailer, if it moves outward pulling down it's bottom pull, outwards pulling up it's top pull.
