Front shifting will never be the same thanks to a great new invention by Sam Patterson – the inventor of Grip Shift™. The Patterson Transmission delivers rocket fast front shifting every time. This invention will change the way you ride your bike. Now you can use your front shifter any time to get the gear you want right now. Secure and precise. Unaffected by pedal speed or load. Once you try it, you will never go back to multiple chain rings again.
