My newest bike is a fixed gear Wabi. The frame is polished steel. I picked the bike up last week and have been putting it through it's paces, mostly on the flats of the Los Angeles Basin, of course, as well as up and down some hills.
I have a few bikes, and different kinds of bikes. When I ride fixed, I feel like I'm 25 years old again.
