Shimano XTR CS-M9001 11 Speed Cassette

Shimano XTR CS-M9001 Cassette

Focus and determination defines you. You are streamlined and efficient. You embrace the most difficult challenges and refuse to give up. You never make excuses, you never stop trying. You conquer mountains from the bottom up, never satisfied with only the descent. You crush the whole loop, every pedal stroke a relentless assault on gravity, your competitors and your personal records. You are XTR and XTR is you. Seriously fast. Confident. Experienced. XTR is committed to rewarding your every effort and has the pedigree to deliver. Dripping with performance, the XTR M9000 drivetrain will not only transfer every watt of energy from pedal to wheel, it will seamlessly shift between perfectly spaced gears allowing you to maintain critical rhythm and momentum over any terrain. You tell yourself you can race without XTR, but you won’t. Never second guess your first instinct.

Rhythm is the essence of smooth power transfer and proper gear step is the key to maintaining rhythm over varied terrain. Keeping a consistent cadence has never been easier with the CS-9001. The XTR CS-M9001 11-speed 11-40T cassette is not only the widest range cassette Shimano has ever produced, but also it’s most balanced. Thanks to its Rhythm Step progression, it maintains calculated, shock-free gear steps from one gear to the next; saving you energy and helping you maintain your rhythm on the trail. Rhythm Step keep your cadence consistent by keeping gear steps as evenly spaced as possible. At an average 80 rpm cadence, each shift results in a 10 rpm cadence change, a managable jump that you'll be thankful for, especially in the big cogs during technical climbs. The XTR CS-M9001 cassette fits on a standard Shimano 9/10 speed mountain freehub and requires no special freehub driver, making the upgrade to M9000 simply a build kit upgrade and not a wheel upgrade as well. A HG-X11 specific tooth profile interfaces perfectly with Shimano's HG-X11 chain, ensuring that shifting performance is flawless and second to none.

Please choose the CS-M9000 if you plan to use it on a 1x or 2x (single or double chainring) drivetrain. The CS-M9001 is an updated version that is compatible with 1x, 2x and 3x (triple) cranksets as well.

Features:

  • HG-X11 specific tooth profile
  • Compatible with Shimano 11 speed chains only. We recommend the XTR HG-901 chain for use with this cassette.
  • Carbon/aluminum spider design for weight savings
  • Aluminum, titanium and steel cogs for a balance of weight savings and durability
  • Rhythm Step gear progression offers the most efficient and largest number of useful gears when paired with Shimano cranksets
  • Tooth Count: 11-13-15-17-19-21-24-27-31-35-40
  • Compatible with standard 8/9/10 speed Shimano MTB freehub, no special driver body needed. For true 11-speed freehub bodies, such as "road" freehub bodies, a 10-speed conversion spacer will be required for use with this cassette.
  • Weight: 328g

M9001 is now officially suitable for 1x, 2x and 3x
FYI - Originally the m9000 was for 1x and 2x, then the m9001 was released for 3x (due to shifting issues and strength for 3x)

Shimano has now advised that going forward, the m9001 will be the only cassette (suitable for 1x, 2x and 3x).

There is still considerable confusion over this, and the boxes have not yet been updated.

Buy it. If you can take advantage of the sale price here, do it!
Went on a short lived SRAM excursion, I have found myself back into the Shimano family.

Great range , smooth shifting, it simply functions with no thought. At $149.99 on sale. The value is there.

I highly recommend this if you are looking for top of the line weight and performance.

Shimano just gets it.
Shimano just gets it because they are finding solutions to use your current equipment with new upgrades. Compatible with 10-speed hub, lightweight, shifts clean and consistent, reasonable price. Excellent.

My only hope is they release a wider range XTR cassette with a 9-46T or 9-50T range. Then, I am moving back to all Shimano.

It states the max rear cassette cog is 42t, yet Shimano has their 11spd 11-46t cassettes in this same line, are they compatible with 46t or is there another offering from shimano which is?

Shimano XTR RD-M9000 11S Rear Derailleur
BEST ANSWER: Hello - If you are running a single front chainring, then you can use the 46 tooth cassette with the GS (medium cage) derailleur. If you have 2 or more chainrings up front, you will need the SGS (long cage) rear derailleur.
can you use a 9001 as a 1 x set up? (Vs using a 9000? confused about the 1x-2x on 9000 vs 3x on 9001
Fred T on Dec 26, 2016
BEST ANSWER: You are correct about Shimano compatibility indicating m9000 for 1x and 2x chainrings and m9001 for 3x. The see the Jenson site lists the m9001 as "11-40 single/double/triple". I am using a m9001 on a 1x with no problems. On referring to the Shimano tech documents site it shows drawings of both cassette types with the 7 smaller cogs being completely interchangeable. I suspect the 4 larger cogs on the m9001 may have different sprocket carriers that may be stronger to accommodate the extra torque a small 24 tooth chainring on a triple could generate. As I say, I have not had any issues using a m9001 on a 1x drivetrain. I can also recommend the cs-m8000 XT cassette which I also run on my mountain bike 1x. I like the ability to use a 42t sprocket and XT is cheaper than XTR and I do not detect any huge shift differences but I am not a pro level rider. If you run a 1x system I recommend using a SRAM 11 speed 1x chain to reduce or eliminate back pedaling chain derailments. I have found the PC X1 to be good value for money. Hope this is helpful.
Will this work with Sram xx1 derailleur?
A shopper on Dec 18, 2016
BEST ANSWER: Yes
Is this a single piece cassette or can I change out the largest ring for a 44 tooth? Also in another question someone recommended using a SRAM 11 speed chain, however in the description it says only compatible with a Shimano chain, can anyone help clarify?
A shopper on Jan 10, 2017
BEST ANSWER: The Shimano XTR cassette comes in 3 pieces. Therefore you cannot swap out your largest ring. I would go with Shimanos new XT 11-46 and be done with it. And yes you can run a SRAM 11 speed chain on Shimano cassettes but won't get the max life or shift crispness.
Will this work with a Di2 derailleur such as the M9050 ?
A shopper on Mar 13, 2017
BEST ANSWER: Yes, I use this M9001 cassette with my XTR 3x11 and Di2 M9050 rear derailleur. Love the system - it works fast and flawlessly. The extra chain tension of the M9050 rear derailleur, allowed by Di2 electronic shifting, means I have no chain slap, no drive train noise, and no dropped chains in nearly 2 year and 4000 miles of technical riding.
