Miche X2 RD R92 Dura-Ace Chainring 55T Power Meter

X2 RD is the chainring designed for those who demand the maximum: lightweight, stiff, and capable of transferring every watt with absolute precision.

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).

Both are compatible with Miche R12 inner chainrings as well as original Shimano ones, giving riders different setups.

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-machined AL 7075-T6 aluminum plate merges with a structural 3K carbon layer, creating a unique synergy that delivers extreme stiffness, lightness, and top-level responsiveness in power transmission.

Every Watt Matters

• With X2 RD, it’s not just about pushing harder: it’s about maximising every single watt you produce, transforming energy into speed, and feeling the difference with every pedal stroke.
• Every watt saved is not just efficiency: it’s time, it’s performance, it’s results.
