I'm surprised nobody had mentioned yet, CLB' way of putting the icing on their weenie Professionel sidepull brakes by using their brake cable set with Dural wound casings.I did it on my weight weenie Vitus Carbone Plus 7 weenie project bike. It contributed quite a bit to getting the bike to 16 pounds..... but the cable casings were so compressible and squishy that it feels like I lost over one third of the braking power than if I went with conventional wound steel casings. I really wonder how CLB would sell such things with any concience, especially if the lives of the cyclists they sold these to, depended on it.......... C'est la vie!!??
