With lengths from 160 to 175 mm, the ULTEGRA crank arms now also cater to smaller cyclists, triathletes, and those wanting to try shorter crank arms. An integral part of Shimano's new 12-speed road lineup, the FC8100 crankset builds on Shimano's legendary chainring shifting and drivetrain efficiency. With new refinements for smooth 12-speed shifting, the ULTEGRA crank arm is now offered in lengths from 160 to 175 mm and provides more performance and compatibility for smaller cyclists, triathletes, and cyclists with specific biomechanical requirements.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eShimano color: Series color.\u003c\/li\u003e\n\u003cli\u003eSales model code: FCR8100.\u003c\/li\u003e\n\u003cli\u003eShimano item code: Crankset.\u003c\/li\u003e\n\u003cli\u003eCycling discipline: Cycling.\u003c\/li\u003e\n\u003cli\u003eUse: On bike.\u003c\/li\u003e\n\u003cli\u003eCrank arm length (mm): 170mm.\u003c\/li\u003e\n\u003cli\u003eBolt circle diameter: 110mm.\u003c\/li\u003e\n\u003cli\u003eChain guard: Without chain guard.\u003c\/li\u003e\n\u003cli\u003eCrankset technology: Hollowtech II.\u003c\/li\u003e\n\u003cli\u003eCrank arms: 4.\u003c\/li\u003e\n\u003cli\u003eCompatible chain: HG+ 12-speed.\u003c\/li\u003e\n\u003cli\u003eGear speed: 46\/36T.\u003c\/li\u003e\n\u003cli\u003eNumber of rear speeds: 12 Speed.\u003c\/li\u003e\n\u003cli\u003eChainring: Double.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Shimano","offers":[{"title":"160mm \/ Grey","offer_id":52723602096474,"sku":"IFCR8100MX66","price":209.0,"currency_code":"EUR","in_stock":true},{"title":"165mm \/ Grey","offer_id":52723602129242,"sku":"IFCR8100AX66","price":209.0,"currency_code":"EUR","in_stock":true},{"title":"170mm \/ Grey","offer_id":52723602162010,"sku":"IFCR8100CX66","price":209.0,"currency_code":"EUR","in_stock":true},{"title":"172.5mm \/ Grey","offer_id":52723602194778,"sku":"IFCR8100DX66","price":209.0,"currency_code":"EUR","in_stock":true},{"title":"175mm \/ Grey","offer_id":52723602227546,"sku":"IFCR8100EX66","price":209.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0532\/7139\/6534\/files\/Guarnitura-Shimano-Ultegra-FC-R8100-46-36-All4cycl-0.png?v=1763060478","url":"https:\/\/maisoncalyx.shop\/en\/products\/guarnitura-shimano-ultegra-fc-r8100-46-36","provider":"All4cycling ","version":"1.0","type":"link"}
