Not only do the lightweight crank arms, manufactured using \u003cstrong\u003eHollowtech II\u003c\/strong\u003e technology, contribute to this, but also the uniquely designed chainrings which feature a \u003cstrong\u003eHollowglide \u003c\/strong\u003econstruction and ensure fast as well as smooth shifting. The result is responsive acceleration from any speed securing the 2x12-speed crankset an absolute top position.\u003c\/p\u003e\u003cp\u003eVarious crank arm lengths and chainrings with 50-34 to 54-40 teeth offer variability and an optimum gear ratio for every riding situation.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003ch3\u003eHollowtech II\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\u003cp\u003eThe guiding principle of Shimano's Hollowtech II technology is the perfect balance between stiffness, stability, weight and rotational efficiency. The goal was to produce a crank that minimises the effort required for the drive and enables more efficient power transmission.\u003c\/p\u003e\u003c\/li\u003e\u003cli\u003e\u003cp\u003eAn exclusive forging process allows the production of extremely light crank arms that nevertheless guarantee maximum stiffness. The fixed connection of the right arm to the axle of the bottom bracket and its external bearing also serve an optimum relationship between stiffness and low weight.\u003c\/p\u003e\u003c\/li\u003e\u003c\/ul\u003e","brand":"Shimano","offers":[{"title":"50 - 34T","offer_id":56690651595138,"sku":"IFCR9200CX04","price":500.09,"currency_code":"GBP","in_stock":true},{"title":"52 - 36T","offer_id":56690651627906,"sku":"IFCR9200CX26","price":500.09,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0958\/7110\/7458\/files\/FC-R9200-54-40T-shic219-primary_1.jpg.thumb.1280.1280.png?v=1784003623","url":"https:\/\/ibkbike.co.uk\/products\/set-crankset-chainrings-shimano-dura-ace-fc-r9200-170mm-12s-black","provider":"IBKBike | Online Bike Shop \u0026 Cycling Equipment","version":"1.0","type":"link"}
