Customer Reviews

The Miche X2 RD is a high-performance outer chainring designed for cyclists who demand ultimate rigidity, reduced weight, and zero wattage loss. Crafted through a precise synergy of CNC-machined AL 7075-T6 aluminum fused with a structural 3K carbon fiber layer, the X2 RD eliminates flex under heavy loads, ensuring crisp front derailleur shifting and immediate energy transfer with every stroke.

Tailor-made for Shimano's modern 12-speed drivetrains, Miche offers dedicated models: the X2 RD R92(designed for Dura-Ace R9200 with options from 50T up to 56T) and the X2 RD R81 (designed for Ultegra R8100 in 50T, 52T, and 54T). Engineered to fit seamless aesthetic contours of both standard and power-meter equipped cranksets, riders can pair the outer ring with Miche R12 inner rings or original Shimano inner chainrings for complete setup customization.

 

Highlights

•    Carbon + AL 7075-T6 Construction: Combines CNC-machined aluminum strength with structural 3K carbon layering for extreme stiffness and lightweight performance.

•    Seamless Shimano Integration: Specifically contoured for Dura-Ace R9200 and Ultegra R8100 crank arms, fully supporting Power Meter models.

•    Broad Gear Range Options: R92 model available in 50, 52, 54, 55, and 56T configurations for racing, climbing, and time trials.

•    Flexible Inner Ring Pairing: Compatible with both Miche R12 inner chainrings and stock Shimano inner rings.

•    Maximum Wattage Efficiency: High structural rigidity prevents chainring deflection under sprint torque, delivering crisp, precise front shifts.
