This is a very durable spur gear and a perfect fit. But I went back to a nylon spur gear because the steel gear makes alot of noise. I also feel that the nylon gear helps protect other drivetrain parts should something go wrong. I have never had problems with stripping nylon spurs.Just wanted to try out a steel one. Will not be using it and would not recommend.
