My dream bike changes with whatever type of riding I'm doing at the moment, and as my riding preferences and skills evolve. I'm very lucky to have a stable of nice road and mountain bikes, as well as a pretty kick-@zz commuter. None are particularly high-end, but I built most of them from the frame up, and they have my favorite components as well as lots of sweat equity. Even the "stock" ones have been tweaked to my preferences.

If money were to rain from the sky, I'd like to add a steel or Ti "road sport" bike for multi-day supported tours, all-day rides, etc. to the stable. Something like a Gunnar Sport or a Singular Osprey. I'd also like to swap my full-suspension frame with 26" wheels for a short-travel full-suspension frame with 29" wheels. The Salsa Spearfish seems like an ideal candidate. Finally, I'd buy a steel disc-compatible cyclocross frame as a replace frame for my current commuter, and build up some sweet disc-compatible wheels to match.
