Our opinion

Lightweight and rigid, the Miche X2 RD 81 external chainring will help you transfer every watt of power into pure speed.

Jose Angel G. M.

Inexhaustible climber, winner of the 2006 Tour of the Basque Country

The battle for watts in modern cycling relies on cutting-edge technology, as exemplified by this Miche X2 RD 81 chainring. Designed for the most demanding cyclists, it promises to maximise every watt produced at the pedals to save time, thereby achieving better performance and, consequently, better results.

The chainring is manufactured from a CNC-machined AL 7075-T6 aluminium plate fused with a 3K carbon structural layer, creating a clever blend of stiffness, lightness and responsiveness. This external chainring version is designed for Shimano Ultegra 8100 cranksets; it is compatible with Miche R12 internal chainrings and original Shimano chainrings. Available in several tooth counts (50, 52, 54), this Miche X2 RD 81 chainring will appeal to all cyclists seeking marginal gains.

Technical specifications:

- Tooth counts: 50, 52, 54
- Shimano Ultegra R8100 12-speed compatible chainring
- Weight: 127 grams (50-tooth)
- Material: Carbon + AL 7075 T6 / CNC
- BCD: 110 / 4-bolt
- Brand: Miche
