Just spend another $200 and get the SBP shift kit.

Me too, expected a story about jerks.

Still think the SBP shift kit will solve all his problems.

Howdy 4yk4a. Both suggestions would work for you. andy at Kings and sick bike parts

Please let us know how it goes and what you decide. You could probably switch another manner of brakes but Keeping the disk breaks is a good idea. IMHO.

Was thinking about this. If you have a one speed rear wheel laying around with a coaster brake, would work too. Be a shame to give up disk brakes for coaster though. I tried to find a way to convert to "pull" brakes but all's I found was how to convert to disk. Think Andy at king's might be the best route.

I have been wondering for a while but read some where today of some one who removed the disk and placed the sprocket in it's place. Would be a great mod if you could get it to work as both sprocket and disk for braking. that would be one of the best mods ever. The tensioner might need relocation. I am going to have to find a junker and try this.

There is always a way.

Norman, how hard would this be to do in theory? disk brake/sprocket. Or any thoughts?
