Surly Karate Monkey

I bought a Surly KM frame to replace my NukeProof Scout frame. I wanted a more utilitarian hardtail. I recently retired and want to do day long adventure rides. The Surly Karate Monkey frame has surpassed my expectations. Very comfortable bike, I feel like I go pedal it all day, with a few breaks thrown in there of course. I still have to outfit it with a bag or two, but I think it's going to work out just fine!!
