It features an 11-34 tooth range with cogs sized 11-12-13-14-15-17-19-21-24-27-30-34. The cassette is made from a single block of cold-forged Chrome Molybdenum alloy steel, which is heat-treated, tumble-finished, and electroplated to enhance durability and reduce friction. Its single-block construction removes excess material, making the cassette lighter and easier to clean. The honeycomb design maintains strength while minimizing weight. It includes shifting ramps and profiled teeth to ensure smooth and consistent gear changes. A red aluminum locknut is included for HG11 and HG12 freehubs; using the cassette on an HG10 freehub requires a separate lockring (sold separately). This cassette is silver in color and weighs 203 grams. It is not compatible with SRAM Road AXS or Campagnolo 12-speed systems.\u003c\/p\u003e\u003c\/div\u003e\u003cdiv id=\"seqbpfeatures\"\u003e\u003cul\u003e\n\u003cli\u003eDesigned for Shimano 12-speed drivetrains, compatible with HG 12 freehub systems. \u003c\/li\u003e\n\u003cli\u003eMade from a single block of cold-forged Chrome Molybdenum alloy steel for durability. \u003c\/li\u003e\n\u003cli\u003eFeatures a lightweight honeycomb design that reduces material without sacrificing strength. \u003c\/li\u003e\n\u003cli\u003eIncludes a red aluminum locknut compatible with HG11 and HG12 freehubs for secure installation. \u003c\/li\u003e\n\u003cli\u003eCassette range of 11-34 with 12 cogs for smooth, consistent shifting performance.\u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/div\u003e","brand":"Prestacycle","offers":[{"title":"Default Title","offer_id":42203880194115,"sku":"CASS0668","price":299.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1608\/6187\/files\/FW0149.jpg?v=1790062881","url":"https:\/\/tecopecosafe.com\/products\/prestacycle-11-34-12-speed-cassette-cass0668-bicycle-cassettes","provider":"365 Cycles","version":"1.0","type":"link"}
