    m647 -> m959?

    Anyone know if its possible to convert a shimano m647 to an m959? I've got both pedals and I notice that the only difference is the resin cage. Is it possible to remove the resin cage and still be usable? Or will i need shims and stuff?

    Don't think so. Its the same pedal as the 540/959 but the body and spindle are slightly modified to hold the platform. Maybe you can find some creative way of achieving it but they were not designed to be changed. If you want to change them you should be able to sell the 647's for enough to cover a set of 540's.

    Oh, i already shelled out for the 959, but was thinking of modding the 647 for another bike...

    Any idea whats the diff between the 540 and the 959?


    BTW, I like your avatar. Took me a while to figure out where I'd seen that before...

    The 540 and 959 are mostly exactly the same. The 959 uses hex screws the 540 uses phillips. If you ever need to change the jaws the phillips screws might be more difficult to remove with the grime from normal use. Besides that the jaws on the 540 are chrome plated and the 959's are flourine impregnated to prevent rust. The chrome can chip off more easily. Functionaly they are identical. The difference is in extreme long term durability the 959 might be more easy to service.

    Hmm, is dat all? I think I would have gotten the 540's then, but the 959 and 647 s were all they had in stock. Buying online is a real ***** over on this side of the world... Oh well, at least I can take comfort that what I have is a bit lighter than the 540s.

    Is this chrome similar to that on the old 747 jaws? mine have really taken a beating (hitting rocks and such) with no damage to the chrome plating.
