CYBREI Chainrings

CYBREI Chainrings are both lightweight and stiff. Specifically, CYBREI METARBON chainrings are made from carbon fiber and are some of the lightest chainrings in the world. CYBREI EVO chainrings are made from lightweight aluminum and are thicker than traditional chainrings. This design keeps weight to a minimum while allowing them to be stiffer and provide better shifting, especially under load. These chainrings fit Shimano DURA-ACE 9200, Ultegra R8100 and 105 R7100 cranksets as well as most 110×4 spiders and power meter spiders.
