As to the belt, meh. My chains work and even break, but I fix ‘em (though, has not happened with single speed, come to think of it.). Still, cool idea but sounds too complex for now.

As to Fatty. He is da man!

I read Fatty’s assessment of the belt drive (here) and having not ridden one, his sentiments seem logical. Chains are troublesome, but they work. It’s a forgettable component until you snap one (which hasn’t happened to me in a long time… knocking on wood). As far as SS applications, the specialized frame design really limits compatibility, but it’s pretty fun to think about though. I’d still like to get onboard and give one a whirl. We’ll see.
