Thanks Wayne and Stevan for the info on Campy Gran Sport shifters. Mine are the closed C. The open C would be more aerodynamic with the wind being deflected off the arms of the C and over the A instead of directed at the centre of the A. now I know why I am a slow rider. "Upgrading" to the faster open C would be more expensive but easier than losing the extra 20 lbs off the old engine.
