This means that the maintenance and replacement costs will be less than half of those of the SRAM boxes. As an additional bonus, the Helix Race 12s clusters are backwards and can be used to update your Helix or TRS + 9-50T existing box. The 43-52T aluminum section adapts to the 9-36T steel section for a greater range. When installing the Helix Race box, as with any box, it is recommended to check the wear of the chain. If your chain shows a wear of 0.5% or higher, you will significantly reduce the duration of the wear of your new box. The installation of a new chain with your new Cluster is a much better and cheaper solution.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThe irrigation finish (Intergalactic) has a PVD coating that improves durability and resistance to wear.\u003c\/li\u003e\n\u003cli\u003e12 Speed.\u003c\/li\u003e\n\u003cli\u003eAluminum Custer: 43, 52t.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eBlack colour.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c!----\u003e","brand":"ethirteen","offers":[{"title":"One size \/ Black","offer_id":49249414119770,"sku":"FWS20-134","price":149.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0532\/7139\/6534\/files\/helix-race-bnero.jpg?v=1722859205","url":"https:\/\/maisoncalyx.shop\/en\/products\/cluster-ethirteen-per-cassetta-helix-race-12v-43-52t-nero","provider":"All4cycling ","version":"1.0","type":"link"}
