A replacement rear-derailleur cage machined from 7075-T6 aluminum, designed to drop rotational mass and sharpen shift precision on supported Shimano and SRAM derailleurs. The single-arm geometry runs a single pulley-carrier side plate (instead of the stock cage's two-plate sandwich) and re-routes the chain with the factory guide\/tension pulleys.\u003c\/p\u003e\u003cp\u003eFinish: Black.\u003c\/p\u003e\u003ch3\u003eDetails\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSpecs:\u003c\/strong\u003e\u003cbr\u003eMaterial: 7075-T6 aluminum cage plates\u003cbr\u003eConstruction: single-arm CNC geometry, reduced rotational mass\u003cbr\u003eCompatibility: supported Shimano and SRAM rear derailleurs (varies by SKU — check fit guide)\u003cbr\u003eReuses the factory guide and tension pulleys\u003cbr\u003eWeight reduction: ~10-20g vs the stock cage (varies by donor derailleur)\u003cbr\u003eInstallation: standard rear-derailleur cage swap\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFinish:\u003c\/strong\u003e Black\u003c\/p\u003e\u003ch3\u003eMaterials \u0026amp; Care\u003c\/h3\u003e\u003cp\u003eReuse the factory guide and tension pulleys. Torque the pulley bolts to the derailleur manufacturer's spec. Keep the cage pivot clean and lightly oiled. Inspect for bent or cracked cage plates after any crash. Indexing: after cage swap, re-check B-gap and cable tension — the shift feel may change slightly vs the stock cage.\u003c\/p\u003e\u003ch3\u003eBundle \u0026amp; Save\u003c\/h3\u003e\u003cp\u003eBuild a bundle and save up to 15% off.\u003c\/p\u003e\u003cp\u003e\u003ca href=\"https:\/\/www.enroute.cc\/bundles\"\u003eShop Bundle Builder\u003c\/a\u003e\u003c\/p\u003e","brand":"Sigeyi","offers":[{"title":"Rouge","offer_id":42456905285880,"sku":"SACS-SHR","price":240.0,"currency_code":"CAD","in_stock":false},{"title":"Jaune","offer_id":42456905318648,"sku":"SACS-SHR-2","price":240.0,"currency_code":"CAD","in_stock":false},{"title":"Rose","offer_id":42456905351416,"sku":"SACS-SHR-3","price":240.0,"currency_code":"CAD","in_stock":true},{"title":"Bleu","offer_id":42456905384184,"sku":"SACS-SHR-4","price":240.0,"currency_code":"CAD","in_stock":true},{"title":"Vert","offer_id":42456905416952,"sku":"SACS-SHR-5","price":240.0,"currency_code":"CAD","in_stock":true},{"title":"Noir","offer_id":42456905449720,"sku":"SACS-SHR-6","price":240.0,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0446\/6373\/4429\/files\/SIGEYISACSSingleArmCageSystem.png?v=1775616086","url":"https:\/\/checkout.enroute.cc\/fr\/products\/sigeyi-sacs-single-arm-cage-system-black","provider":"enroute.cc","version":"1.0","type":"link"}
