Description
Shimano brings 10-speed technology to their MTB groups with Dyna-Sys shifting technology. The XT-level CS-M771 picks up where its 9-speed cousin left off with HyperGlide tooth profiles for reliable and precise shifting, while a new massive 11-36 gear range will spin you up the steepest hills. Plated steel cogs ensure durability with machined cutouts to bring down the weight. The six largest cogs are pinned to two alloy separate alloy carriers (three to each) for further weight reduction and extra-stiff performance. Includes an alloy lockring. Specifically optimized for the asymmetric CN-HG94 10-speed chain.

Works best with Dyna-Sys chain
This has been a smooth shifting and durable cassette for me, with a great choice of gear ranges for the hilly gravel terrain I like to ride. Shifting is best using a Dyna-Sys compatible Shimano CN-HG95 XT 10-Speed Chain (be sure to mount this assymetric chain with the labels facing outward - it also plays well with a KMC 10 spd powerlink). I found that a regular 10 speed road chain would sometimes have trouble shifting between the smaller cogs and the ramped larger cogs.

It is a cassette
I mounted this on my Giant Anthem 29'er. It shifts smoothly and reasonably quietly. It does what a cassette is supposed to do carry the chain and help it move from cog to cog.

Perfect Cassette for a 2X Gravel Setup
Shifts very well with any 10-speed chain and will work with SRAM or Shimano hubs. Just make sure you have a mountain hub (wider) or use the 1.85 spacer underneath it on the standard road hub.

Great range of cogs!
This and the right chainring up front can get you over most anything! The 11T helps when you're picking up speed on the flats while the 36T is like a good friend when the grade kicks in at 22%.

Great, cost effective cassette
I bought this for an entry level cross bike extra wheelset. It works great so far and didnt cost an arm or a leg.

Nice Cassette
Great cassette for our road tandem to help with steep rides. We have the 11-32 tooth cassette set up with an Ultegra long cage derailleur and it works great.
