I can see the bikes are not all the same. On mine you could swap the brake and sprocket and also would need to swap the asymetrical axel bushings. Things would line up then. Have to reverse the tire too if it is a monodirectional tire-I run a Turf Saver so not an issue. But hey it's bad enough that the valve stem on mine is under the brake rotor. Unless someone has a clever solution I'm making a custom rotor that will insure I can get a clean shot at the valve stem-putting on hydrolic rears anyway and putting the old brakes up front.
