SHIMANO Deore XT 10-Speed Cassette 11-36 T, Durable Plated Steel Cogs with Alloy Spiders

SHIMANO's CS-M771-10 Deore XT cassette is a 10-speed, 11–36T sprocket cluster built for long-lasting durability and efficient shifting without excess weight.

This Deore XT cassette blends plated steel cogs with lightweight alloy spiders to deliver a durable, responsive gear range suitable for trail, cross-country, and mixed-terrain riding. 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.

What makes this cassette durable but still light?

The 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.

• Plated steel cogs for abrasion resistance and consistent wear life
• Two lightweight alloy spiders carrying six large sprockets
• Individually mounted small cogs to save weight and simplify replacement
• Alloy lockring that secures the stack while trimming grams

How does it improve shifting performance on climbs and descents?

HyperGlide tooth profiles and precisely spaced 10-speed indexing ensure predictable chain movement between gears, reducing lag and chain hang. The cassette’s spread from 11–36T gives close ratios at the top end for speed and larger jumps low down for climbing without compromising shift quality.

• HyperGlide sprockets guide quick, accurate shifts under load
• Tight upper-range spacing (11–21T) for smooth cadence control at speed
• Wide lower-range gears (24–36T) for easier climbing options
• Compatible with Shimano Dyna-Sys 10-speed drivetrains for optimal indexing

Is it easy to install and maintain?

Yes — the cassette fits standard Shimano 10-speed freehub bodies and uses a conventional alloy lockring for secure, tool-friendly installation. Routine maintenance is straightforward: clean, inspect the cogs for wear, and replace individual rings or the entire cassette as needed depending on chain wear and riding conditions.

• Standard spline fit for common Shimano freehubs
• Alloy lockring for simple tightening with a cassette tool
• Modular cog layout simplifies targeted replacement of smaller rings
• Recommended with matched Dyna-Sys 10-speed chain and shifter

Who is this for? 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.
