    External BB/crank area creaking noise

    Hi,

    I've got a steel frame LeMond with maybe 3000 miles on it. It's a 10spd Shimano drive train with external BB bearing cups.
    I've been riding it quite a lot in the past few weeks and have noticed a new "creaking" sound that happens under high torque situations. The sound is most dominant when my left crank is at the 11:00 position, but is also heard when the right crank is at 1:00. I'm a big 6'3 210lbs rider and climb a lot of hills. I've worn out the old fashioned square taper spindles before with the riding I do. I'm new to external BB, and am unfamiliar with their maintenance.

    During my ride to work I pulled over and tightened my crank bolts with my multi-tool. It's hard to tell if that helped, I think it may have. Am I on the right track with the chain rings or is something else involved?

    Thanks
    -Sean

    You many find the following links helpful in tracking it down:

    AND

    http://www.parktool.com/repair/readhowto.asp?id=123

    It's usually just a matter of patiently removing, cleaning,
    re-lubricating, and re-torquing fasteners until it quiets down.

    Thanks Neil.

    I don't yet own a removal tool for this style of external cup BB. Looking at the park choices, I see two models that will work, but not sure which is preferred:


    I like that I can fit a torque wrench to this one.


    This has that small 8 splined thing to remove the caps. (dont' think my truvativ crank applied to that though)
