Designed for demanding riders, the RFX Pro Series Elite crown made of 7075 aluminum offers strength and lightness to your transmission. CNC machined and CAD designed, it combines precise tooth geometry and tight tolerances for a more consistent chain performance. The mud evacuation grooves limit clogging and help extend the lifespan of both the chain and the crown — a significant advantage on muddy trails or in off-road use.
This crown is aimed at riders who want a reliable and high-performance part without compromising on weight. It is color-coded by brand for easy selection and available in standard silver finish. Ideal as a replacement on contemporary machines such as cross bikes or roadsters that use 520.
