    Hi,

    My '07 Specialized Epic has XT Hollowtech II cranks and Bottom bracket with the external type bearing cups.

    After 8 months of use, there is play in the bottom bracket. Can I adjust the bearings? I have checked the Park tool web site for instruction, but cannot understand it. I understand the black cap on the non drive side of the crank is an adjuster. Do I have to loosen the allen bolts on the crank arms and then just
    tweek that cap with the special tool? :confused:


    Any advise welcome!

    Cheers.

    is the play in the bottom bracket (ie the cups are worn/loose) or are the cranks loose?

    My advice.

    Take the cranks off.
    Take the BB out. Copper grease on the BB threads. BB back in.
    cranks back on.
    test.
