The Good: Keeps the chain on your ring, most of the time! Installation is easy.
The Bad: The steel backplate. For serious riding you should opt for the more expensive version with the aluminum backplate. The steel one is not stiff enough. When you hit sth with the guide it tends to fley so much that everything gets out of shape.Overall Review: This chainguide is good value if you are on a budget. I changed the backplate for an aluminum one and it works so much better in rough times.
