Penta sprocket was designed to protect teeth and the chain after  unsuccessful grinds. Not a small thickness (8.5 mm in the thinnest place) and an impressive 5 mm thick guard.
When we were creating the Penta sprocket, we choosed the aluminum guard because due it’s strong and durable. In addition, it does not unscrew during riding, and it just looks great.
