    I should have returned it when the small cog wouldnt install without filing off a bit, but I had new wheels and wanted to ride
    after approx. 50 miles of admittedly knarly singletrack, bike started making noises and I had to constantly tweak the cable adjuster , chain broke twice so I bought new chain and when I went to switch I was examining the gears and the 3 largest cogs were bent, no crashes,no sticks nothing just pedaling up and over rocks. the only other cassette I ever had do this was anxtr 12/32 with a 4 arm spider, junk pure and simple

    Strengths:Uber-fast shifts, Light, compliments SRAM X.7 components superbly, striking, functional design.
    Weaknesses:None, as of yet.
    Similar Products Used:SRAM PG-950, Shimano XT M770 cassettes.
    Bike Setup:2006 Cannondale Furio Hardtail; Ultra Fatty DLR Headshok w/ rebound/lockout; MAVIC XM117/DT Swiss wheelset; FSA 25mm riser bar/175mm Alpha-Drive crankset; TrueVativ ISIS BB; SRAM X.7 Shifters/rear derailleur; Avid BB5 disc brakes; IRC SeracXC 2.10 tires; Thomson Elite 250mm seatpost/Fizik Nisene HP saddle; Crank Bros. Smarty clipless pedals; SRAM PG-990 11-34 cassette.
    Bottom Line:After the OEM SRAM PG-950 cassette was upgraded to a much lighter Shimano XT-M770 cassette- I noticed that shifts were not quite as crisp, as the original cogset. Although the Shimano cassette worked with the SRAM components just fine- there was something still amiss.

    I was first leery about spending another $100 on a top-of-the-line cassette.....but the PG-990 cassette works in total harmony, with all the SRAM componentry. Compared to the old PG-950 cassette- the weight savings is justified(1/2lb shaved-off). Compared to the Shimano XT-M770(which is slightly lighter).....the SRAM PG-990 with the anodized aluminum spider- is exactly what the drivetrain was missing.....ie; it is the TICKET. Shifts were not only instant(shifts even BEFORE my thumb leaves the lever!).....but every selected gear change is securely and precisely dialed-in, each time, every time.

    The SRAM X.Series 1 to 1 actuation ratio is the fairest trade, of all. No more.....no less. By fully acquiring German precision drivetrain manufacturer SACHS- SRAM has produced another WINNER!!

    Strengths:Great value, reasonibly light, nice looks. Not the big S.
    Weaknesses:Poor build quality, performance not on par with XTR.
    Similar Products Used:XTR, PG-970, older PG-990
    Bike Setup:Trek Top Fuel 110 converted to all SRAM (except cassette now)
    Bottom Line:Seems there are a number of 2006 cassettes with build quality issues in the rivetted aluminum spider. After picking up the cassette on a whim (and on sale), I was warned by a local builder that the 28T and 24T rings like to bent over due to poor rivetting. Sure enough after about 3 or 4 spirited rides I had lost the use of both gears (28T folded out blocking the chain path of the 24T and dropping off itself). I must admit, SRAM has been good about warrantying it, but it will remain a training bike cogset only. Can't afford to lose two climbing gears in a critical situation. 5 for value (can't beat the price), 3 overall for quality control.

    Bottom Line:Wow - what more can i say? i am very impressed on how this has improved shifting. I recently upgraded my drive train from shimano LX. And boy what a difference! I will never go back to Shimano. SRAM rocks! I have to admit the first thing that drew me to this cassette was its flashy color and construction. The spider is made with a solid piece of aluminuim. The only draw back is that the main sprockets are riveted to the spider so if you damage a sprocket you will have to buy a new cassette. Overall, i have been very happy.

    Bottom Line:I had this approx 6 month. About a month ago my rear started skipping when pedaling hard. I thought it was just my deraillor was out of alignment. Last week I was going up a technical climb and skipping bad-wouldnt shift. One of the rivets had come loose on the 3rd cog and the ring was bent outward. Apparently the arms are plastic. I bought the 2006 model to replace as this has apparently been fixed(now aluminum).

    Bottom Line:This is a followup to a previous review I made of the PG-990 cassette. After 500 miles of riding in dry, gritty conditions as well as wet, muddy conditions, I have had absolutely no problems with the PG-990. It has worked perefectly right from the start and shows no signs of weakening. Shifting is still crisp and quick even after the chain and cassette get all gunked up with mud or grit.

    Bike Setup:SRAM X.9 shifters and rear derailleur. PC970 chain. Avid Flak-Jacket derailleur cables.
    Bottom Line:I upgraded a Cannondale with 10 year old LX components to the SRAM componentry mentioned above. After a few hours of easy riding using all the gears I made one tweak to the drivetrain and have had no ghost shifts or skipping chains at all. The shifting is smooth, quick and precise. The PG-990 cassette works great. Time will tell how long it lasts but so far I'm am pleased with the quality.

    Take the time to properly set up your drive train and you will have no problems with this cassette. Make sure your rear derailleur is set up according to spec, your deraileur hanger is properly aligned, and you have a new 9 speed chain for your new PG-990 cassette.

    Bottom Line:This is a follow up review.
    Like the reviwer below I wanted to give the SRAM a test.
    I initally was pleased but it wore out really quick. I have used shimano cassettes for a long time and they wear much better.I replace my chain frequently and I also check it for stretch with a chain check tool.

    The SRAM casstte does not even compare to the 9 speed deore I had on another bike. Durability is very poor. I have put 4000 hard miles on a 9 speed xt cassette and it still shifted nice. I only replaced it because it started to wobble a bit on the free hub body.

    I purchased SRAM X7 shifters and a X9 derailer to give them a try also. I will keep them for sure. The SRAM thumb shifters rock. I am disappointed with the SRAM cassette.

    Shimano makes a beeter cassette. I agree with the reviwer below the test failed. I will give the new LX a go.

    Bottom Line:"Get the same reliable, lightweight performance BlackBox racers enjoy. This top of the line Sram PowerGlide 2 cassette features an ultra lightweight composite spider. The rings are then coated with a satin chrome finish for durability. 290g"

    Err, no. If this is the reliable performance that racers enjoy, then I'll just skip this from now on.

    Speaking of skipping; I bought this in spring of this year. I have changed my chain at least twice during this period, if not 3x. I looked at my chain a week ago to check the "stretch" and it had the correct distance from link to link. I put a new chain on it this weekend (because there are too many power-links in my sram chain and I am worried about it's integrity) and it skips all over the place. It skips because the cassette has worn down, so despite changing my chain (this would be the 3rd or 4th time, I'm pretty good about changing them) this thing has worn out. Drivetrain components wear out, but I get significantly more life out of shimano products.

    This product generally reflects most SRAM products I see as a bike mechanic; just not as durable and reliable as the big S.

    Back to XT, experiment failed.

    Strengths:Not expensive.For the price the weight is really good.
    Weaknesses:Not as durable as a Shimano XT.

    Bottom Line:For the money it works well. It did not work so well with the old LX shifters. They were fairly old and got swapped over when I bought my new frame. I needed to upgrade my aging drivetrain so I wanted to give Sram a go ahead. I put the cassete on the bike with a new Sram chain and rest of the drivetrain was shimano. The shifting was never really that great but I was going to upgrade the rest really soon. With the X7 shifters, X9 derailer and PC99 Chain it works really well.

    It works well with all Sram. I have the 11-34 and I have never owned the 34 tooth for my low gear. I like the 34 tooth alot. I have owned too Shimano 9 speed XT cassetes. One I retired after 4000 plus trail & road miles. The second I bent some teeth on it and Shimano warrantied it and that one is still okay. The XT is a little better quality casste. The 990 works well. I also like the 28 to 34 alot.

    The 34 tooth gear has helped me shell another freehub. Cheap fix.

    Sram has got a really good new line of well priced componets. I like the X7 shifter , X9 med Cage derailer, Sram PC 99 and 990 casste combo alot .

    I ride hard and alot and I will slowly go all Sram. I am 190 LBS and I break parts and so far no problems. Shimano has gotten ridiculous with there cost and constant change over a very short time. I am sold SRAM.
