I know we are not supposed to love material possessions, but right now I am carrying on a hot and steamy affair with my new road bike.I mean hot and steamy as in burning up the calories and sweating profusely — and it's wonderful. Yep, I took the plunge and upgraded from my 10-year-old hybrid to a sweet ride by Specialized. I paid a pretty penny, but I know this relationship is going to last. My bike is by far the most expensive piece of fitness gear I own. What about you?
