John, Super article. I noticed this myself when I put together my Super Torque: hold assembly moves under torque. After about 4k, clicking developed. I took everything apart, cleaned, and re-greased. The Hirth joint was immaculate. I put it all back together with the presribed torque... still the click. I came to the same conclusion as you--that the shell needs to be the perfect width to support Campy's narrow tolerances. I am not sure how to face a shell that is too narrow. I will follow your directions for producing the correct dimensions with washers. This is my first experience with Campy, and I started out with Super Record. It's a little disappointing, frankly. But thank you for confirming the diagnosis, and prescribing the cure. Geoff
