P.219 Chainring made of EXTRON PRO Extron Pro is a high-tech material that offers the following features: It is made of Kevlar. This makes the teeth stronger, reduces running noise, extends durability, and offers less resistance than standard aluminum chainrings. They are suitable for karts with a 219 chain and 6-bolt mounts. It is lighter than aluminum (approx. 40% lighter than other chainrings available on the market), produces low noise, and has a higher load capacity than conventional chainrings. The self-lubricating properties of the material result in a longer service life for both the chainring and the chain.
