    dura ace crank clicking

    Im running a dura ace double crankset with dura ace BB. everytime my right pedal is all the way down (and left being up) it makes a mild click noise. only when pedaling....not just holding that position. i dont know if its the bottom bracket or crank but its driving me CRAZY. i overhauled the BB and it still does it. also overhauled the pedals and kind of ruled them out. it definitely sounds louder when im putting more weight and effort into pedaling and i can barely hear it if im pedaling lightly. any idea what it might be?

    Believe it or not it might be the seat or seat post. You weight transfer and possible thigh rub is enough to make a not fully tight one click like that ... it happened to me too. Had the lbs change out the BB too then someone suggested this and it worked.

    so heres what ive done so far.....

    overhauled the BB, tightened the chainring bolts, adjusted and tightened the BB cups, took out the saddle and seatpost, tightened the crank arms as tight as i could, overhauled and tightened the pedals...

    everytime the right arm hits 6 o'clock....click

    click click click click

    im going to lose my mind. any other ideas? anything that might need to be replaced?

    Other things that click, IME:

    -BB cups - remedy, Teflon tape on the threads , re-install
    -Gear cables, where they slide in the guide under the BB
    -Cable ferrules clicking inside the cable stops on the frame.
    -Front der. cable end hitting the crank (not at 6:00)
    -Something on your cleat?
    -Rear skewer not tight enough
    -Cracked frame, been there, done that. More of a creaking than a click.

    Try riding with a different rear wheel, you never know.

    Re-thread the bottom bracket
    Face the shell
    Grease it like crazy
    Make sure your left crank isn't hitting the derailleur cable.

    If none of those work and nothing up above works, get a new BB.

    what year dura ace are these, what type of bottom bracket do they use, have you checked them for cracks? did you grease anything, or just tighten? you may need to grease the spindle, chainring bolts, seatpost (unless it's carbon), the seatpost head, the rails of the seat, pedal threads.

    the cranks and bb are recent i think. 7410 i believe? double for 9 speed. cranks and BB are octalink. i havent noticed any cracks but i will look closer. the clicking sound is pretty mild but sharp. i heard that cranks make more of a creaking sound. nevertheless ill check it out. its definitely not a crank slipping sound which ive had before....

    what does "face the shell" mean?

    everything you mentioned has been greased except for where the spindle and crank arms meet. which ive read that you arent supposed to grease on octalink because they might slip. have i been misinformed about that?

    you have. grease it. it may not solve your clicking, but then again, it may, and as long as everything is tightened down, no harm will come of it.

    7410 series is 7 speed, i think, and used a square taper bb. 7700 series is 9 speed and used octalink. 7700, 7701, and 7703 are the model numbers that appeared on 9-speed dura ace cranksets.

    Hmm, it would't happen EVERY time your pedal was at 6:00, but make sure your chain isn't too tight.
