I have a Vaya and a Cross-Check, altho neither are set up for commuting.

The Vaya is a long-distance mixed-terrain road bike and I'll be riding it in this years Dirty Kanza 200 race. No racks, no fenders, just Dura-Ace and Stans goodness, it's built for comfortable speed.

The Cross-Check is as a traditional single speed 'cross bike. Lightweight wheels, road drops, Paul cantis, and cx race tires. Used for urban exploring, cx racing, etc.

I commute on my trusty Trek 520, currently sporting rear rack, fenders, swept bars (FSA Metropolis), flat pedals, and singlespeed gearing. Before that it was the bike I rode from Boston to Key West on a loaded tour in 2007.

The Vaya would make an amazing commuter though, and I have had mine set up for that type of riding before. I've taken it on overnight camping trips and hauled crap all over town and it's a super stable, smooth riding do-everything platform.
