Stress BMX Penta Sprocket

The Stress BMX Penta sprocket was designed to protect the teeth and the chain from impact while grinding. It’s nice and thick with it being 8.5 mm in the thinnest place and an impressive 5 mm thick guard.
When creating the Penta sprocket, Stress chose an integrated aluminium guard because it’s strong and durable. Plus, it does not unscrew during riding and it just looks great.
