The Penta sprocket was designed to protect the teeth and the chain after unsuccessful grinds. It’s got a pretty good thickness (8.5 mm in the thinnest place) and an impressive 5 mm thick guard.
When we were creating the Penta sprocket, we chose the aluminum guard because it’s strong and durable. Plus, it does not unscrew during cycling, and it just looks great.
