This is as good as it gets. Fast, practical on all surfaces, comfortable over long distances, capable of substantial loads. It is a true pleasure to ride a quality bicycle. The Karate Monkey frameset is perhaps the most versatile in the surly line up. I have run it as a single speed, a cross monster, a commuter and a full on loaded touring bike. It can do a lot of things, and it does them well. With the current build, I can get the groceries, go camping, chew up singletrack and let skinny tire dudes draft off of me. If I had to own only one bike, this would be it.
....and this is my post-ride vice. When its cold enough, I look forward to even the worst cup of coffee. That is my favorite mug by the way. I use it all year.
