Last time I removed cranks were the ones with the tapered pins. My Gemini has Shimano Hollowtech cranks. I removed the plastic seal to expose the inner core of the crank. There is what looks like an 8mm hex socket. My guess is that I remove this first and that exposes the thread on the inside of the crank. The standard Park Tool crank puller I have will not fit, so I assume I need a special adapter to pull the crank arms off that screws into the crank arm and onto the shaft of the puller?
Has anyone removed these types of crank? I also presume the threads are conventional (anti-clockwise to unscrew) and don't use clockwise removal like pedal threads do?
I need to get these off as (a) I want to use a better bb, and (b) I damaged the front mech cage and it's one of those that fit onto the bb and not the downtube.
