Cool; I'm thinking of turning mine into a compact double as well (46-30 probably). I'm impressed that the NR RD can handle that much chain (27 tooth capacity is probably near its upper limit). I'm going to run a campagnolo rally since I'll run a 13-28 on the rear.
Are you running a cup and cone BB or a modern sealed unit?
