Miche X2 RD is the gear designed for those who demand the maximum: lightweight, stiff, and capable of transferring every watt with absolute precision. Developed for Ultegra 8100 cranksets with three targeted configurations: 50, 52, and 54 teeth, maintaining the same construction philosophy. Both are compatible with Miche R12 internal cogs and with the original Shimano ones, offering different setups for every need. The hallmark of this gear lies in its meticulous engineering and the uncompromising attention to detail that we have always brought to our products: an aluminum plate in AL 7075-T6 CNC-machined fused with a 3K carbon structural plate, forging an alchemy that creates a unique combination that guarantees extreme stiffness, lightness, and a transmission with ultra-high responsiveness. The dedicated design makes them compatible for cranksets with or without a power meter, ensuring impeccable performance in every configuration.\u003c\/p\u003e\n\n\u003cul\u003e\u003cli\u003eWeight (g): 540T (Power Meter Ready) 170 g.\u003c\/li\u003e\u003cli\u003eSpeeds: 12-speed.\u003c\/li\u003e\u003cli\u003eMaterial: Carbon + AL 7075-T6 \/ CNC.\u003c\/li\u003e\u003cli\u003eBCD: 110 \/ 4-bolt.\u003c\/li\u003e\u003cli\u003eCrankset compatibility: Miche \/ SHIMANO® Ultegra R8100.\u003c\/li\u003e\u003cli\u003eAvailable tooth counts: 50 - 52 - 54.\u003cbr\u003e\u003c\/li\u003e\u003c\/ul\u003e","brand":"Miche","offers":[{"title":"54 \/ Black","offer_id":53581693845850,"sku":"CVI814","price":199.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0532\/7139\/6534\/files\/Corona-Miche-X2-R81-powermeter-110bcd-54T-All4cycl-0.webp?v=1771009465","url":"https:\/\/www.all4cycling.com\/en\/products\/corona-miche-x2-r81-powermeter-54t","provider":"All4cycling ","version":"1.0","type":"link"}
