I've seen a bunch of bikes now with cable housing used the full length of the cable. And I had someone tell me that this is an improvement over using stops and having open wire. Who actually believes this is an improvement in dérailleur control? Can you prove to me that it is an improvement? Remember, I was building frames when we opened up cables for cleaning and lubrication. Should we do a test? I need to be convinced that this is more than a fashion statement.
