    Which chainset? There'll be a number on the back of the pedal hole, FC-M5xx. Hollowtech refers to the crank manufacturing process rather than anything to do with BB fittings.

    It could be a Hollowtech 2 (confusingly unrelated to Hollowtech), if the axle is integrated into the RH crank, or Octalink, or Square Taper!

    Irrespective of which model it is you don't have to use a 9 speed cassette though.

    The Deore Chainset generally comes with a BB if its Hollowtech2.

    Should be compatible with 8 speed cassette and chain I think.

    Just checked the chainset and on the back of the crank arm it mentions Shimano M530/531. and looking on the internal there seems 8 notches for the bottom bracket?
    so would it be Hollowtech 11 or octalink?

    octalink.

    and will work with 8 with no probs.
