I'm rolling a Surly Karate Monkey single speed as my commuter and am currently running Serfas Seca 700cx28 tires. I have mtb risers on there and the road vibration is pretty intense at times... especially for a cat who’s broken his hand twice this year.
Anyhow, I'm looking at the possibility of playing around with a larger tire volume to suck up some of that vibration. I want something with minimal rolling resistance as well as something with some puncture protection that will handle the rigors of a rough daily commute. A couple of tires that have stood out to me are the Schwalbe marathon series, the WTB slickasaurus, the Panaracer T-serv to name a few.
