Originally developed for E-MTBs to deliver long service life and a wide gear range with fewer gears, it quickly proved itself on unpowered MTBs as well. All cogs are stamped from steel, with the larger ones pinned to alloy spiders for added strength and durability. Due to its origins, it remains the most durable cassette in the range. Available in two versions, the standard 11-50T is suited for traditional MTB use, while the 12-50T E-Bike version features slightly adjusted gear spacing optimized to handle the unique torque and load demands of E-MTB riding, offering smoother power transfer and increased longevity.\u003c\/p\u003e\n\u003cp\u003e\u003cbutton class=\"accordion__title js accordion-is-open\" data-accordion-trigger=\"description-2\" aria-controls=\"description-2\" aria-haspopup=\"true\" aria-expanded=\"false\"\u003eFeatures\u003c\/button\u003e\u003c\/p\u003e\n\u003cdiv class=\"accordion__body no-js-accordion\" id=\"description-2\" data-accordion-body=\"\"\u003e\n\u003cp\u003e\u003cspan class=\"metafield-multi_line_text_field\"\u003e�Prime 9 Technology\u003cbr\u003e�Our Most Durable Cassette\u003cbr\u003e�Steel Stamped Cogs\u003cbr\u003e�Lightweight Alloy Spiders\u003cbr\u003e�Ultra-Wide Ratio with Consistent Progression\u003cbr\u003e�Also Available as 12-50T for E-bikes\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan class=\"metafield-multi_line_text_field\"\u003e\u003cbutton class=\"accordion__title js accordion-is-open\" data-accordion-trigger=\"description-3\" aria-controls=\"description-3\" aria-haspopup=\"true\" aria-expanded=\"false\"\u003eSpecifications\u003c\/button\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cdiv class=\"accordion__body no-js-accordion\" id=\"description-3\" data-accordion-body=\"\"\u003e\n\u003cp\u003e\u003cspan class=\"metafield-multi_line_text_field\"\u003e�Process\/Material\u003cbr\u003e�Cogs: Stamped \/ Hardened Steel\u003cbr\u003e�Spider: CNC \/ 6061-T6 Aluminum\u003cbr\u003e�Lockring: CNC \/ 6061-T6 Aluminum\u003cbr\u003e�Finish: ED Black\u003cbr\u003e�Speeds: 9\u003cbr\u003e�Non-Ebike Gear: 11 - 13 - 15 - 18 - 22 - 28 - 34 - 42 - 50\u003cbr\u003e�Ebike Gear: 12 - 14 - 16 - 18 - 22 - 28 - 34 - 42 - 50\u003cbr\u003e�Compatibility\u003cbr\u003e�Platform\u003cbr\u003e�Ebike\u003cbr\u003e�Non-Ebike\u003cbr\u003e�Driver: HG Freehub Body\u003cbr\u003e�Cross Compatibility\u003cbr\u003e�Chain:\u003cbr\u003e�Box One Prime 9\u003cbr\u003e�Box Two Prime 9\u003cbr\u003e�Box Three Prime 9\u003cbr\u003e�Weight: 645g\/22.7oz\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan class=\"metafield-multi_line_text_field\"\u003eBX-CS2-P9A1150-BK\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Box","offers":[{"title":"Default Title","offer_id":49254095618294,"sku":"BXCSL002","price":249.0,"currency_code":"HKD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0088\/4051\/1550\/files\/13.22213.6603.1_58076517-44aa-45dc-b99e-9933f68d471a.webp?v=1761892320","url":"https:\/\/ferrobike.mom\/products\/box-two-prime-9-cassette-11-50t-black","provider":"ferrobike.mom","version":"1.0","type":"link"}
