I commute year round on my "good" road bike. Yes, it gets more wear and tear than if was pampered in some air conditioned shrine, but I just like riding it. I'm prepared to have to replace parts as they wear out. I've never tried SRAM, but my last bike had 105s. I now have Campag Veloce which I much prefer. The shape of the hoods just suits me and I really like the thumb up-shifter for the rear mech.
