Welcome to yet another rider of the (nearly) oldskool!!
I've just jumped back in after 10 years out and I'm loving it. Took me a good few weeks reading different posts and websites before I could get my head round all the new brands available and the ones which seem to have all but disappeared.
Not really the best person to advise on bars, stems, etc as I'm still using my old Azonic world force risers and Specialized stem at the mo but I will highly recommend a step to running single speed and a FFW, easily the best choice I made when it came to rebuilding my bike with a front disc as a close 2nd!
