That means ongoing service and replacement costs will be less than half that of SRAM™ cassettes. As an added bonus, Helix Race 12s clusters are backward compatible with and can be used to upgrade your existing Helix or TRS+ 9-50T cassette. The 43-52T aluminum section will fit on your old 9-50T steel section for increased range.\u003cbr\u003e\nWhen installing the Helix Race cassette, as with any cassette, we recommend checking chain wear. If your chain shows 0.5% or more wear, you will significantly decrease the wear life of your new cassette. Installing a new chain with your new cluster is a much better and more economical solution.\u003cbr\u003e\nThe Intergalactic 42-50t cluster features PVD finishing which improves durability and wear life.\u003cbr\u003e\nPRODUCT SPEC\u003cbr\u003e\nMaterial 2 aluminum cogs, 10 steel cogs\u003cbr\u003e\nRange 9-50T: 556%\u003cbr\u003e\nSpeeds 12-Speed\u003cbr\u003e\nTeeth\u003cbr\u003e\nAluminum Custer: 42,50t\u003cbr\u003e\nSteel Cluster: 9,11,13,15,17,20,23,27,31,36t\u003cbr\u003e","brand":"Ethirteen","offers":[{"title":"FW2URA-107","offer_id":51246770192608,"sku":null,"price":389.0,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0763\/3738\/1600\/files\/Helix_Race_Cluster_12_speed_9-52T_ethirteen_Nickle.jpg?v=1774755838","url":"https:\/\/bikeapprentice.co.nz\/products\/helix-race-cluster-12s-9-36t-e-thirteen-nickel","provider":"Bike Apprentice","version":"1.0","type":"link"}
