Trying to figure out what bottom bracket tool is needed to get the original BB off a D9. I thought it was a Shimano/ISIS 20 slot internal spline one? The slots in the cups do not look like the pictures I've seen here Park Tool Co. » BBT-32 : Bottom Bracket Tool : Bottom Bracket though. The BB cups have 4 groups of 3 small slots spaced by 4 larger slots, but maybe this tool will fit..

My BB is clunking on every downstroke - either bearing gone or loose cups.
