Compatibility with Dura-Ace 9200 and Ultegra 8100 groupsets
The X2 RD R92 and the X2 RD R81 stem from the same vision but are designed for different targets.
Maximum freedom of choice
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.
Its dedicated design makes it compatible with cranksets that have or do not have a power meter, ensuring flawless performance in every setup.
Because every watt matters
With X2 RD, it’s not just about pushing harder: it’s about maximizing every single watt you produce, transforming energy into speed, and feeling the difference with every pedal stroke.
Miche’s engineering process represents a rigorous synthesis of advanced design, technical development, and construction quality at the highest standards.
Every watt saved is not just efficiency: it’s time, it’s performance, it’s results.
