I've been having the same problem. I just got a new State Fixed gear with FSA compact drop bars. It's 55cm and I'm 5'9. I just ordered a pair of nice gel padded gloves. When I got the bike the saddle was all the way back, I've moved it more towards the center and that seems to have helped a bit. I'll probably take it to an lbs and ask them to fit it for me if the gloves don't help and/or my hands just get more used to riding. (It's been a while.)
