Have you guys ever tried braking that way? It works pretty damn well, you'd be surprised. I'll bet he can skid as well as any fixie, it just probably takes longer for him to swing his leg up there. He doesn't do it in the video but I'll bet he can brace his foot against the non drive side chainstay and use the side of the tire or rim to stop as well. Overall, I'm thinking its not so much worse than riding a fixed brakeless, which I also think is a little crazy but we don't need to go there.
