Clicking noise only high cadence

Anyone have a clue what could be causing it? I have an Ultegra 6500 crank w/ those external bearing cups and the sound seems to be coming from down there.

When on my trainer no noise except when going over 110 RPMs. I checked chainring bolts ok, seatpost tight, any suggestions before I take it to the LBS?
thx

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

AND

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

If high cadence = low gear (small front ring); check for foot or pedal ticking the piece of derailleur cable that extends past the cable bolt.

I had a saddle that used to click at higher RPM's. Just a thought.

Depending on the pedal, it could just be a slightly loose plastic cover that only wiggles around at high cadence. That was the case with my old style time road pedals.

Depending on the shoe and cleat combo, you might have a unused cleat bolt that moves when you reach higher RPM's.

if it's clamped into a trainer, it could be the QR skewer slipping around from frame flex.
