My favorite bike of all time is...My Next One!
I like to always have TWO in the stable. That way I'm never down. I have my Madone, and Specialized Crux (bigger tires). I had a Mtn. bike, but the positioning made my hands numb.
I wish I had a flat place to be able to hold a good pace. Best I can do on my 25 mile rides each day is 15. Hills, traffic, etc.
