Wow, you guys have me beat big time. I have one. Just one. I've used it for a triathalon, road riding, and now commuting. It's an '04 Specialized Allez Elite. I love the bike but I may consider getting a dedicated commuter by the end of the summer. The Spec looks a little funny with rack/lights/fenders and aero bars. Oh well....
My wife has 2 mt bikes, neither of which are rideable at the moment. The '93ish ProFlex is just beat. Nobody makes elastomers for the rear susp anymore. The '91ish Trek 800 is due for a refit this spring, it will be reborn! It's currently in a sad state of repair however. The frame is good and it will get most of the components off the ProFlex so it will ride again.
