Check out this jammer from the Pedal Revolution blog:
On second glance I noticed the Clarence bars on it. I think this bike has bright future. Apparently the rack was not even a stock feature, it was hanging around the shop waiting for the perfect mate, and I believe this is it. Very cool bike from a very cool shop.
If you haven't been, check out Pedal Rev in person. They are some of the nicest folks around, and they have a great selection of new and used stuff, as well as great social mission (find their story here).
