The design balances strength and low mass by pinning the larger sprockets to two minimal alloy carriers while mounting the smaller rings individually, all secured with an alloy lockring. It’s engineered to work smoothly with Shimano Dyna-Sys 10-speed shifters and rear derailleurs and uses HyperGlide tooth profiles for guided, quick gear changes.\u003c\/p\u003e\n\n\u003ch3\u003eWhat makes this cassette durable but still light?\u003c\/h3\u003e\n\u003cp\u003eThe CS-M771-10 pairs plated steel sprockets with machined alloy spiders to remove unnecessary metal while keeping high-wear surfaces strong. Three large cogs attach to each spider to reduce fastener count and weight, while the smaller rings are separate to optimize engagement and wear characteristics.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003ePlated steel cogs for abrasion resistance and consistent wear life\u003c\/li\u003e\n  \u003cli\u003eTwo lightweight alloy spiders carrying six large sprockets\u003c\/li\u003e\n  \u003cli\u003eIndividually mounted small cogs to save weight and simplify replacement\u003c\/li\u003e\n  \u003cli\u003eAlloy lockring that secures the stack while trimming grams\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow does it improve shifting performance on climbs and descents?\u003c\/h3\u003e\n\u003cp\u003eHyperGlide tooth profiles and precisely spaced 10-speed indexing ensure predictable chain movement between gears, reducing lag and chain hang.

Riders who want a robust, performance-focused 10-speed cassette that blends durability with lightweight construction will appreciate the CS-M771-10. It’s particularly well suited to mountain and mixed-terrain cyclists who need a reliable 11–36T gear spread, riders upgrading to Shimano Dyna-Sys 10-speed systems, and anyone who prefers cassettes built for frequent shifting under load without excess mass.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Is the CS-M771-10 compatible with my Shimano 10-speed shifter?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes, it is designed for Shimano Dyna-Sys 10-speed shifters and rear derailleurs for correct indexing.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can I replace individual cogs on this cassette?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: The smaller four cogs mount separately and can be replaced; larger sprockets are pinned to alloy spiders.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"SHIMANO","offers":[{"title":"Default Title","offer_id":48030577819809,"sku":"B003EAU5CG","price":173.36,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0758\/6532\/5729\/files\/shimano-deore-xt-cs-m771-10-front-view.jpg?v=1791406678","url":"https:\/\/canadiansporting.ca\/products\/shimano-cs-m771-10-deore-xt-10-speed","provider":"Canadian Sporting","version":"1.0","type":"link"}
