That was an idea I hadn't thought about. Thanks. Actually it was last Saturday when a guy in the LBS mentioned the idea of the seat stay pieces to help keep it from being able to rotate on me and throw the wheel off center. That wasn't my own idea. I had thought about it but couldn't see a secure enough way of achieving what I knew the do thanks to the rounded nature of the back side of the dropout on the bike itself. I hadn't thought about extending the 'brake' up above the vertical dropout. Dumb me.
