bosses aren't too short. the danged inside washer is too thick. I have 2 pair and they are both a couple of mm too thick.

"...Campagnolo retrofriction shifters were mounted on my Pinarello..."

Man, I'd love to have a pair. But they are too pricey for me. I watched a pair of Super LJ retrofrictions last night go over $100...I scrounged a pair out of my parts pile (never been on a bike!) last year to go on my wife's 770. I'm thinking maybe she needs more modern shifters...What was the year and model of your Pinarello?
