I'm feeling foolish this morning. The endcap torque is indeed increased by tightening the clamp screws. I tried unscrewing the endcap on my install and it is indeed very tight. I quess the clamp screws load the bearings up. Another reason for feeling stupid is I asked myself "What has changed?" I'd forgotten I'd raised my seat a 1/4" So I went out and rode out of the saddle... No click. Sit on the saddle click returns. Loosen clamp on CF seatpost, turn post in seattube around a couple times. Retorque and click sounds completely different (much, much less). I wonder if I need some "frame prep rosin???" or whatever it called?
