Ok, folks you were all wonderful last time. I need some more help now. I have a late 70's Raleigh International. Last summer I asked for help on upgrading the crankset to help get up the hills. I decided to go the cheaper route. I ended up with a Campy Veloce Compact Crank. Works just fine. The problem now is the Super Record RD is just too extended. Even use the tricks, I'm not comfortable. I want to upgrade. I have a narrow six speed 14-28 on the back and 50/34 on the front, which gives me a 30 chain wrap. I want to stay Campy, so I have a couple of questions. First are all modern Campy RDs capable of being used in a friction mode? Second, according to Campy's web site, with that chain wrap and cog I'm into a mid cage range. I've read a couple of articles that say the short cages are rated fairly conservative. The SR RD has about a 45mm cage. Most newer Campy short cages are 55mm. Is that enough or do I really need a med cage?

Thanks.
