    Is it ISIS? If so, get another ISIS BB in the same size.

    depends on the cranks really.

    Looks like they are truvativ hollowtech 2 style cranks (giga pipe or something?)
    in which case you'll need either an truvativ gigapipe BB or one of the compatible superstar components ones. they both offer versions for about £20.

    edit: search for GXP bottom brackets, not gigapipe, sorry

    if it is a two piece it is external bearings.

    just get new bearings/cups.

    Have a look on the crank. Does it say 'GXP' or 'ISIS' ion the arms anywhere?

    anytear - as a guide Spesh have specifications of their bikes on their website, follow link to bikes>archive. These are generally fairly reliable if you're having difficulty identifying a component.

    Any - same bike as me - definitely a GXP Stylo - it says it on the crank arm!
