Today I went with Mike down to recycled cycles to get his new bike (well, it is used, but new to him). It is a pretty nice Trek commuter bike and the price was definitely right. We rode back together. Personally, I was amazed at how much better my bike was riding. I'm not sure what caused it, the clean chain or the recently inflated (with my new pump) tires, but the bike was silent while riding and was much easier (I could feel my input being directly translated into forward motion, with negligible loss). I must say, it was a great feeling to get back. I'll have to clean my chain more often (and now I can pump the tires up to higher pressures more easily). Excellent.
