    Removing this Suntour Superbe BB?

    Attempting to remove this Suntour Superbe cartridge bearing bottom bracket, but the cups won't budge under the affect of my adjustable spanner (http://www.parktool.com/product/pin-spanner-green) - the pins keep slipping out of the grooves.

    Does anybody know of a suitable tool that will give me enough grip to get these things out? They seem to be in there pretty tight.

    Thanks

    Unfortunately, I think that tool does not fit; it specifies an 43mm outer diameter, which a few mm too large for this spline.

    Search over on C+V. There obviously is/was a special tool made for these but they are apparently pretty rare. Park made an adjustable spanner with square pins that might be a tad better but not much. You might need to make your own tool by grinding down something suitable.

    Thanks for the information.

    I was able to get both cups out with my adjustable spanner by pressing down on the contact points very hard while turning. A sturdier spanner may also have helped.

    Cheers

    May be a one way removal, but a drift punch and a good sized hammer
    will exert the needed force to drive the thing around.

    as long as the frame doesn't move around too much .

    Don't forget your to wear safety glasses
