Strengths: Light(244g for 11-34)
Stiff, thanks to the 5-arm alloy spider assembly
Shifts fluidly in all gears
Great gear range, for XC/trail rider
Weaknesses: Too many titanium cogs. Shimano actually used SIX ti cogs, on this model cassette. The one-piece, integrated carrier and spider assembly is incredibly stiff, but the middle ti cogs may bend, due to high torque mashing. This is really a spinner's cassette.
Bottom Line:
A great, solid cassette, with a few design flaws. The Achilles Heel of this cassette is the titanium 23t cog's tendency to momentarily bend, resulting in skip, while applying heavy torque. The one-piece freehub carrier and five-arm spider is actually very stiff...making the pliable titanium cogs the next weak links.
The 34t low cog offers relief on super-steep, 25% grade climbs. Plan all shifts, before applying torque, and this cassette will last you many thousands of trail miles. This cassette is the same weight as the new CS-M970 cogset, except the carrier and spider is now in three sections. The M953 cassette is made for the rider who likes to spin and climb. Shimano don't make cassettes of this quality anymore!

Strengths: Weight, shifting
Weaknesses: none
Bottom Line:
This cassette has lasted great for me pulling loads and kids up and down hills. I'm really happy w/ how it works. I have been happy with it from the get-go. Pushing 2k miles on it right now, no signs of wear.
I did just switch to my winter wheels and left the previous cassette on there, which is XT or LX and I have to say it performs about identically, w/ no derailer adjustment. Perhaps shifters are my limiting factor.
Re the bending thing, mine has a 5-arm spider, that might make a difference relative to the 4-arm ones. And I am a lunatic spinner, I do not mash just about ever.
I will try one more xtr cassette on my mtn bike, which has xtr shifters, and see if those pull some extra performance out of it. If not, well, it's been fun to use and I'm glad I tried it but I'm not sold on the sticker price.

Strengths: I've just had to retire my XTR cassette because the 8th cog wore out. Too bad we can't buy the the "loose" cogs for replacement. I'm not complaining though as I got an amazing 4400 miles of trail riding on this thing since my Blur was new in 2003. I did meticulous chain maintenance and changed them once a year.
Weaknesses: The replacement price is crazy. Too bad individual cogs not part of the main cassette body are not available otherwise I could still be riding this cassette even after 4400 miles.
Bottom Line:
I had a great experience with my XTR cassette but I replaced it with Sram PG-990.
Bike Setup: Santa Cruz Blur. Cross Max SL rims w/ceramic bearings, Vertical Pro UST tires, Thomson Elite stem w/Easton carbon riser bar. Scram XO trigger shifters, XO derailleurs, Selle Italia Flow saddle w/FSA carbon seatpost, FSA mega EXO crankset, FSA ceramic bearing bottom bracket, Hope Mono Mini discs.

I never post on these things, but I am amazed at the negatives on this product. Either Ive been lucky, or there is alot of misuse going on out there. On the same cassette for years without a worry. They are pricey-but titanium usually is.

Strengths: Lots of teeth.
Weaknesses: The gears bend under load.
Bottom Line:
The XTR Cassette is not suitable for use in the real world. The customer assistant at the bike shop (Performance in Chandler, Arizona) where I bought the replacement recommended that I buy steel XT, even though the shop also stocked the higher-priced titanium XTR in stock. According the to shop guy, about 1 in 10 of the XTR cassettes will bend before they wear out.

Strengths: Weight, Bling factor
Weaknesses: Durability
Bottom Line:
This is the 2nd XTR cassette I have used and both broke. The 1st broke at the spyder while cruising up a hill. I grabbed another at a LBS while on a road trip. This one shifted great and was not showing much wear but suddenly about 2" of the 32 tooth cog was gone. I was on a climb but nothing too radical. I am a clydsdale rider and that may have contributed but I will not spend $100+ on a light weight cassette again. I cannot recommend these based on value and durability.

Strengths: light weight, strong,
Weaknesses: price is rediculous
Bottom Line:
With proper maintenence, common sense and finesse any cassette will last long. For all of you having problems with shifting to lower gears going up hills I would strongly suggest switching over to rapid rise. Shifting uphill or under load is not an issue and drive train parts for the most part, last a lot longer. Of course you will have to learn to shift backwards if using shimano triggers. (I am not familiar with sram shifting) I did not find that to be a problem.
The price of the xtr cassettes are way out of hand, for that reason I will be switching back to sram. I hear the ladies love the new red spindals and red lock rings. Sram cassettes are a few grams heavier at half the price of xtr with just about the same performance.

Strengths: light weight, shifts well
Weaknesses: Expensive. No performance weaknesses
Bottom Line:
Durability not an issue here. I check in at 200 plus, rides include steep technical climbs that require shifting, never had a problem. Have used for two yrs, 2/3 rides wk, 8 mos of the year, in the widely varying conditions, mud, dust, snow, ice, etc. Has minimal signs of wear. Keep your chain clean and fresh (three chains so far). Make sure your shifters are properly adjusted (another story with shimano). Would I buy another? Probably not, there are alternatives far less expensive, with equal performance. I had to try it once, racers need it light, I don't. I'm in the process of switching complete drivetrain to sram (Race Face cranks), will use current Shimano part on back up bike for buddies.

Strengths: Light, shifts well
Weaknesses: Durability -- bent the two largest cogs after less than 100 hours riding.
Bottom Line:
As someone below pointed out, I could probably have extended the life of the cassette by never shifting on a climb. But my preference is to change to something more durable, add a few grams, and shift whenever I like.
I can't downgrade it too much, since you've got to expect to sacrifice some durability in exchange for light weight, but for me at least, the trade-off isn't worth it in this case.
Smooth shifting even on uphills. With proper maintenance, this cassette has lasted through 2 years of Pisgah, Tsali, Manastee, Yankee, and Custar, as well as winter riding through grimy snow. It works and the shifts remain smooth as silk.
Strengths: light, hasn't broken or bent, shifts well
Weaknesses: more likely to bend than xt? damn expensive new
Bottom Line:
This cassette came on an almost year old bike, I purchased almost two years ago. It has survived about twenty races and countless training rides and crashes. I know that any product line contains variance in quality (I think i got lucky in that respect), but in a nutshell i believe 95% of cassette problems are caused by poor shifting technique. The other 5% might be poor mechanic skills (chain is stretched beyond spec or derailluer needs adjusting) and poor quality from the factory.
DON'T SHIFT WHILE GRINDING UPHILL... Do shift while pedaling easy just before and until after the shift is complete.
This is a lightweight component best for experienced racers. Beginner and intermediate riders should not waste their money.

Strengths: Lightweight, and that's the only positive I can think of. Can we say stupid light.........
Weaknesses: Bent large cogs. shifting performance is sub par and that's an understatment. Pricey.
Bottom Line:
Shimano needs to recall this product. It's spoiling there XTR rep for quality products. I have used Shimano components for 17 years and the XTR line has been for the most part top notch. I went ahead and returned the item to my Cannondale dealer and had it replace with an XT 11/32 cassette with some $100 of credit left over. The XT cassette shift great.......

Strengths: Looks totally trick, but looks can deceive...
Weaknesses: Weak...period... Busted the big cog on a moderate climb, not even cranking full torque...
Bottom Line:
BIG DISAPPOINTMENT!!! I am with the others on this... This cassette is WEAK!!! I have only been riding my Jekyll for a few weeks, and to not bend, but BREAK a cog the way this one broke is unbelievable... Never have I seen a freewheel/cassette get trashed so easily. I am having it replaced (by Cannondale under warranty), but I fear I will trash the next one. I am a 220 lb XC rider with above average torque-ability, but nothing that should cause this kind of total metal failure... Hey, welcome to the world of XTR... I am starting to hear all the pro-XT stories and believing them... I suspect before the end of the year I will have "downspec'ed" to XTs..... Shimano???? How 'bout "Shame-an-you".....

Go for XT at almost a third of the price. No reason to use the XTR at all. It sucks (no pun intended. The XT shifts fine and can last over 1000 miles (though I'd always say change at 500 miles for serious XC users)for about $50 or less. Use with Race Face as a top line set-up
