Sprocket Hub Adapter - Gas Bike Bicycle

This adapter is for mounting a sprocket for a gas powered bicycle on the rear wheel. This keeps the sprocket centered and in alignment when installing. Much easier to use than the traditional rubber spacers from gas bicycle kits. Use appropriate bolts, washers and nuts. In the attached picture the back 2 piece hub was not used from this design. It would be bets to use the largest washers possible to spread out the forces.

Printed in ABS. PLA might work as long as it does not get to hot.

I have tried this on multiple 26" wheel sizes and it works with most spoke patterns.
