I've been keeping my eye on the Civia Bryant with belt drive for some time. It looks like close to my ideal commuter. The frame has almost exactly the same geometry as my current touring bike I use for commuting, and I know that fits me well. The Bryant frame has eyelets for front and rear racks. I like the idea of lower maintenance belt drive and internal gears. I think the swappable drop outs on the frame make it very versatile. Disc brakes are a plus too. The only thing I don't like is 32h hubs. I don't understand why 36h hubs weren't selected.
Does anyone own one? Universal Cycles recently got a few in stock and I was close to buying one, but currently they are sold out again.
