Every watt you generate deserves to be transmitted with total efficiency.
X2 RD is the chainring designed for those who demand the maximum: lightweight, stiff, and capable of transferring every watt with absolute precision.
he X2 RD R92 and theX2 RD R81 stem from the same vision but are designed for different targets.
The R92 has been designed explicitly for Dura-Ace 9200 cranksets, offering the broadest range of chainring options, from 50 to 56 teeth (50, 52, 54, 55, 56). The R81, on the other hand, is designed for Ultegra 8100 cranksets with three dedicated configurations: 50, 52, and 54 teeth, while maintaining the same design philosophy.
The essence of this chainring lies in its meticulous engineering and the incredible attention to detail we have always put into our products: a CNC-machinedAL 7075-T6 aluminum platemerges with a structural3K carbon layer, creating a unique synergy that delivers extreme stiffness, lightness, and top-level responsiveness in power transmission.
Its dedicated design makes it compatible with cranksets that have or do not have a power meter, ensuring flawless performance in every setup.
