congrats on the Roubaix and yes this can be a very expensive sport/hobby but it also has a direct relationship to your overall health/happiness. For me if I actually use the bike I don't mind paying whatever it takes for me to enjoy it more and use it more(within reason of course). While I'm mostly a recumbent guy I can totally relate. There are much worse hobbies that we could be out there doing. Having said that and as long as I can still afford it I don't see a problem spending $$$ on them.
