I took my bike in to the shop at lunch today, and I had them replace the tube in the back tire (the bike was long overdue for its post break-in tune-up anyway, and they don't charge for maintenance or installation of anything). They finished working on it before the end of the day, so I already have it back home. I left there with two extra tubes in my saddle bag, and the patch kit of course.

I gotta say, what's with these damn colored valve caps? Bright red? Yellow? I was like WTF? Black all the way man, my bike is dark blue after all. They gave me a few extra black caps.
