The four largest sprockets are machined from titanium, and the mid-section spider carrier uses carbon fiber in place of aluminum, keeping the overall weight remarkably close to its 10-speed predecessor despite the added cog.\u003c\/p\u003e\n\n  \u003cp\u003eShimano's Hyperglide sprocket profiling defines how this cassette performs under load. Shift ramps and tooth profiles are positioned to guide the chain with control and consistency — whether you're sprinting through a transition or sitting down on a long climb. The 12-25 option offered here suits riders who want closely spaced ratios across a range that covers most road terrain without large jumps between gears.\u003c\/p\u003e\n\n  \u003ch3\u003eShimano Dura-Ace CS-9000 Cassette Specs at a Glance\u003c\/h3\u003e\n  \u003cul class=\"specs_at_a_glance\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSpeed:\u003c\/strong\u003e 11-speed\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSprocket range:\u003c\/strong\u003e 12-25T\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLarge sprocket material:\u003c\/strong\u003e Titanium\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSpider carrier material:\u003c\/strong\u003e Carbon fiber\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Shimano 11-speed road drivetrains\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Shimano","offers":[{"title":"12x25 \/ No Color","offer_id":43594277716012,"sku":"ICS900011225","price":169.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/shimano-dura-ace-cs-9000-cassette-2078810.jpg?v=1771294694","url":"https:\/\/ricycles.com\/products\/shimano-dura-ace-cs-9000-cassette","provider":"RA Cycles","version":"1.0","type":"link"}
