Swap out rear derailer or not?
Between a Shimano Crane and an Exage rear derailer, is either any better than the other?
I got an Exage for free and it has metal jockey wheels and a b-adjust on it, but I don't know if it would be any real improvement over the Crane on my road bike (chrome Benotto).
I could always just desecrate the Crane and transplant the jockey wheels I suppose...
(It's too crappy out for the roadie, I'm looking for things to tinker with.)
