It is an excellent work-around for gearing problems, but be prepared to get shafted!

The part came in two days.It went on effortlessly.I adjusted motor,chain tesion,tigtened up and rode it: 15 minutes.I have a NUVINCI rear wheel,So the 11 tooth sprocket helped the super low gear ratio starts.Smoothed out gear changes,Increased top speed.Excellent service,part!
