Hyper glider.

For their Dyna-Sys 10-speed system, Shimano added another cog to their venerable XT level cassette. So like the previous 9-speed versions, the CS-M771-10 XT Cassette has the same Hyperglide tooth and ramp shapes to help the chain move effortlessly across its range.

The XT 10-Speed Cassette uses plated steel cogs for superior durability, but that doesn't mean that it weighs a ton. The largest six cogs are minimal in design and are pinned to two lightweight alloy spiders -- three cogs for each spider. The four smallest cogs go on separately, and the whole batch is secured with a sleek alloy lockring. This cassette is compatible with Shimano's Dyna-Sys 10-Speed shifter and rear derailleur.

The Shimano CS-M771-10 XT Cassette is available with three different cog options -- 11/32t, 11/34t, and 11/36t.

The cogs are configured as follows:

  • 11/32: 11-12-14-16-18-20-22-25-28-32
  • 11/34: 11-13-15-17-19-21-23-26-30-34
  • 11/36: 11-13-15-17-19-21-24-28-32-36
  • Plated steel cogs
  • Compatible with Shimano’s Dyna-Sys 10-speed shifters and derailleurs

The description says "Nov-36". Should it be "11-36"?

Works Like It Should

    This was surprisingly a nice upgrade from the stx cassette that came stock on my bike. Lighter and the cog teeth are ramped to facilitate quicker, smoother shifting which was very noticeable even if you screw up and happen to shift under torque load.


    • Familiarity: I've put it through the wringer

    The weight in the specs is obviously wrong. It is likely also not the claimed weight. Likely 100 grams more. Some homework needed.

    Hard to beat

    • Familiarity: I've put it through the wringer

    Shimano's XT grupo has always been top notch for the price range and this cassette is no different. Pair it with a Wolf Tooth or OneUp larger cog in a 1x setup or use it in a classic 2x style setup. I've done both and can't find a problem!

    works great, not the best wear

    • Familiarity: I've put it through the wringer

    I'm on my third in 1.5 years on my trek remedy so I'd ding it slightly for durability, but it's a nice cassette for the money.

    Paired up with a Wolf Tooth Giant Cog

    • Familiarity: I've put it through the wringer

    The cassette pairs up perfectly with the 42t Giant Cog from Wolf Tooth! (17t cog removed)

    Solid cassette

    • Familiarity: I've put it through the wringer

    Slapped this cassette on my Scott Genius along with a Wolf Tooth 42 cog and I couldn't be happier. The shifts are crisp and because it is a Shimano, I know it is built to last.

    Can't go wrong

    Great cassette as always from Shimano. Used it to convert my cross bike to a 1x10 for commuting and have had zero issues. Works great with a Sram drivetrain.

    Works great, long lasting

    • Familiarity: I've put it through the wringer

    Great shifting and durability makes this cassette/drivetrain one to keep until they come out with the 1x15 group.

    Quality product

    • Familiarity: I've put it through the wringer

    Shimano components live up to their reputation. Crisp and smooth shifting.

    Great upgrade

    • Familiarity: I've used it several times

    The Shimano XT cassette was a nice upgrade on my rear drive along with other XT components. High quality and a solid component from Shimano.

    Best 10 Speed Buck Banger!

    • Familiarity: I've put it through the wringer

    I just replaced my m771 cassette the other day that had around 2200 miles on it. I bet I could have easily hit 3k on it, but alas, I am converting to a new 1x setup. Since I am making the conversion, I thought I would replace pretty much all of my drivetrain. Right now, my bike is all XT, so I figured I would stick with that since I've had great luck with it.

    In addition to the new cassette, I've even added a new Wolf Tooth GC (42t) for making climbs easier since I am losing my granny on my old 2x setup.

    If XT is a bit too rich for your blood, essentially, you can always snag the HG81 (SLX series) for a tad less; however, your middle cogs will be riveted together unlike the m771 version.

    I have 10 speed Ultegra 6700 grupo. Want a 32 tooth low cog. Please advise.

    I have a road bike with Ultegra 6700 Ten speed grupo. I want a 32 or 34 or 36 tooth 10 speed cassette to work with Ultegra 50-34 crank. Do I need a long cage der.?

    I have the same setup and same problem. You will max out on a 11-32 cassette. From my research you want to buy: Shimano M771 9 speed rear derailleur. See:

    Wolftooth Giant Cog Modification

    • Familiarity: I've used it once or twice and have initial impressions

    I purchased this cassette to support a Wolftooth Giant Cog (40t) conversion of my 1 x 10 drive train - works incredibly well all put together. Check out the Wolftooth web site for more information.

    I opted for the Wolftooth 16t cog to replace the cassette 15 & 17 cogs and I think that was the right move.

    So far so good (1 ride), but will check back later in the season.

    Don't forget to buy a new chain if you're going to convert to the GC.

    I did the same as you, well, went with a 42t, but totally lovin' it!

    xt cassette

    • Familiarity: I've put it through the wringer

    works awesomely, until it breaks. I rode it pretty hard for 2+ years, until the alum arms for the larger chainrings sheared and broke. just ordered another.

    something to note: these later models (2014+) fixed an issue that the earlier (circa 2012) models had: the older model's small cassette chainrings had narrow profiles with spacers between the rings. Since the interface between the chainrings and freehub body was as narrow as the chainring teeth themselves, if you pedaled hard, the chainring would cut into (and mar) aluminum freehub bodies. The newer models have the spacers between small rings integrated into the rings themselves, thus increasing the interface area between ring and freehub body, and reducing the marring of the freehub body.

    What does the 11-36 weigh?

    • Familiarity: I've used it several times

    This cassette weighs 335.4 grams.

    Hello Dan,
    What size new chain will fit on this? Will 11 speed chain work?

    XT Quality

    • Familiarity: I've put it through the wringer

    This cassette is super durable and shifts crisp. Exactly what you come to expect from Shimano. I have it paired up with single ring in the front and it works great.


    • Familiarity: I've put it through the wringer

    Shimano line of xt is the excellence of mid level builds, great equipment for the price!
