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.

- Weight: 328g
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.

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.

If you're in need of a larger gear ratio try it out with a Wolf Tooth 45 t cog.

Q & A
I meant to say 11-40 can be used with a 2 or 3 gear front set up. Thank you for catching that.
I am sure you could use 2 chain rings in the front if you wanted but the point of having 11 or 12 speed wide ranging cassettes is to be able to run a single ring up front. I have this cassette and run a 32 tooth chainring in the front and I find it to be adequate.
The 9000 is a road cassette designed for road bikes
