Finally decided to build up my road/cross bike and going to treat myself to a brand new groupset. What are peoples opinion on the 4700 vs 5800? Other than lighter and having an extra cog at the back - is it really worth the extra? (~£220 4700 and ~£340 for 5800) I know people speak well of both, I've used both and they seem to work almost exactly the same - anything I'm missing?
