When I installed the idler, I noticed the chain never would stay in the middle, and it would always go either to the left of the idler, or to the right. No matter where I slid the idler, the chain would always be rubbing on the left or right side. With that said, the rubbing did not really affect the idlers spinning, and the idler still spun smoothly. One thing to note is that the kit does not come with the bolt that attaches to the cycle genius bicycle. Most people will probably have the bolt, so that wouldn't be a problem, but it is worth mentioning.
