I put the cables on today and the brakes work much better. I used the Jagwire Hyper set that I ordered 4 years ago. As soon as I put it together, after playing around with the original cables, I knew that was the solution. The cable was just so much smoother, even though the old cable felt OK. I also filed down the holes in the bars so that the housing didn't kink at that point. The levers themselves are still not up to par with modern stuff though. My cheap Tektros beat them hands down (pardon the pun). But the bike is all original, even one of the tires (Clement Criterium Seta), but I'll put my extra pair of Keos on to ride it. I still have the Campy pedals, and one of the original clips with the Zi logo. And probably a clincher rear wheel as none of the other tubulars I have are any good, unfortunately I don't have any good gumwall tires to match the front either. I think I still have an MA40/Campy wheel.

I need new bar tape now. I'm going to look for something more old style than the current padded tape. I'll see if I can find some cloth tape locally.
