In an ever expanding and ongoing quest to maintain some level of fitness and be green, I am building up a Surly Karate Monkey to use as a Single Speed commuter to and from work, the liquor store and rides with the family. I am trying to figure out if I want to run the Mary Bars (shown) or try out some Dirt Drops. Any recommendations/comments for a grocery-getter commuter as far as which of these two bars to run and why? I'm pretty close on this build, just awaiting my tires; Schwalbe Big Apple 2.35's to arrive and this beast will be rolling. I plan to do full fenders, racks and panniers in the future. I'm pretty psyched. Between this bike and my new Greasecar, I should be traveling for minimal dollars and using almost zero gas, ever!
