Well, I'm not sure how guys are with their bikes.
But, I know I could never sell it, never let anyone borrow it, and I have this strange desire to keep buying new things for it. I wipe it down fairly often. I would never store it outside, even in the garage.
And, when I ride past other people, I think "My bike is cooler than yours!" Even if they have some tricked out LiteSpeed or something. Usually when I see someone with a tricked out bike like that just riding around the lake, they are someone with way too much money on their hands...with a kick a.ss bike that they can't ride for more than a 14mph average (and I am passing them).
I will never get rid of my bike, unless I begin to outperform my equipment. Meaning, I will go and get a more aero dynamic, lighter bike, with all the bells and whistles, when I am so good, even the seconds accumalated from draft will make a difference. Right now, that is not an issue and will not be for several years.
