Thank you, Fred. As you're no doubt aware, many clubemn did just what you say, and used their only bike for racing, touring and commuting, and the derailleur would make it that much more versatile; indeed, the Cyclo "Oppy" (the model on my Granby) was produced as a racing derailleur, though I doubt whether it had the cachet of the Simplex or Super Champion!
