Dizzy

Hello, I am currently riding through Europe headed for Montpellier where I'll be living for a couple of months. I'm looking for a good and reputable place to do full service on my Tracer, as well as upgrading the bike. So question number 1 is: location of a good workshop on French southern coast/northern spain. Question number 2: What are the best upgrades I can do on the bike for around 1000-1500euro. Quick shift and suspension might be interesting! Thanks a lot in advance!
