Hi Peter, all. I have very little experience w/ the Campy GS derailleurs. Most of that on an early '60s Olmo w/ half step gearing. I have to say both f & r shifted fine over a range like 48/51 in front and 14-22 or so in back.The pushrod type ders. may be more prone to fouling up in the wet, but do a decent job when clean and lubed and used w/in their intended range. Typical front gaps were only 3-6 teeth when these were in use. The later version of the GS, the Valentino was often paired w/ a 40/52 up front and a 14-28 in back which couldn't have helped. But notice that virtually every modern front der. is a paralellogram type similar to the original Campy Record. Cheers.

I second the question: Just how crummy are these Campy matchbox derailleurs - and is the crumminess universal, or only in the lower gruppos (Valentino, Velox)? I have a Frankensteined Gran Sport derailleur (with a replacement Simplex cage) that's going on the front of an early '60s Follis with half-step gearing. Should I be nervous about reliability, or is it just less responsive relative to more modern derailleurs? -- Peter Adler Berkeley, California/USA
