3 bikes, no tubes. If you're looking for light, the setup on my SingleSpeed isn't bad. The Kenda single-ply/non-UST casing is weaksauce though, I'd be careful about running this setup on a bike I ride aggressively.
I ride the Blur the most and that setup is great for traction, but rolling resistance is a little more than I'd like. I'm thinking about changing out that rear tire for something like the Nobby Nic 2.35 UST or Maxxis Crossmark 2.25 UST.
