Todd asked:
>>> Having serious slippage problems with Campy clamp-on D.T. shifters mated to Nuovo Record derailer.I have the d-ring adjuster tightened to the maximum tension and I'm still getting slippage under load.Anyone have a trick or two up their sleave to fix this?<<<

And Steven added:
>>>This is usually indicative of the screw bottoming out before the proper friction is reached, because it should theoretically be possible to tighten the d-ring such that you can't even move the lever. I would suggest grinding down the screw ever so slightly and retightening......<<<

I agree with Steven's assessment of the problem, something I've also encountered numerous times. Another fix is to "shim" the assembly with an additional washer under the outer domed cap.
