I need to fit a Shimano UN54 bottom bracket ( ... elID=17473), but I can't for the life of me work out which tool I need. The bottom bracket is the square taper kind, but this tool: ... elID=17704

says it's for "ISIS-Splined/Octalink". Does anyone know if it will fit, or is there another version?

thanks in advance

    It fits square taper too. It's just that it clears the splined axles that other tools might not. ... tem=BBT-22

    "Below is a sampling of the types of cups and rings serviced by the tool. "

    I use a cheaper Cyclo version for square taper BBs. Never had problems with it.

    FWIW all Shimano cartridge type, square taper and Hollowtech I and ISIS use the same tool
    Make mine an Italian, with Campagnolo on the side..

    Go for the spanner type tool, ie one that needs an adjustable wrench to turn. As you can use the crank bolt to secure the tool which you can't do with a 1/2" drive.
    I've added a signature to prove it is still possible.
