Enjoy the same reliable, lightweight performance that SRAMs BlackBox racers enjoy. The 990 cassette has been updated with a trick anodized aluminum lockring and spider that shaves grams over previous setups. The cogs are blast chrome plated for a durable, attractive finish.

Works great with SRAM drivetrains, of course, but also totally compatible with Shimano 9sp equipment, so theyre a great upgrade for any 9 speed bike on the market.

Weight: 272g(11-32)
305g(11-34)
Material: Alloy carrier
Aluminum lockring
Steel cogs
Compatibility:

9 speed SRAM or Shimano drivetrains

    I use this cassette for XC riding and racing.

    Great cassette, no problems. Doesn't leave horrible bite marks on the hub's aluminum freehub body like my old Shimano cassette did.

    Used in conjunction with SRAM PC971 chain, X9 rear shifter and X9 rear derailleur.

    I had the 11-32 and it weighed 271g.

    I really don't want to complain, but I've only had 3 rides on the cassette because it started skipping it's middle gears almost immediately after installation. I inspected for the cause and found the 18 ring (smallest on the spider) is bent toward the 21 ring causing the chain to ramp up as it comes around. My first thought was "I've damaged my first cassette in 14 years of MTB," so I decided to harvest an old XT cassette off my wife's bike to see if the chain was also damaged because I couldn't see any impact marks on the cassette or chain. Like magic, the old XT mounted and operated like it was pre-adjusted. I've ridden once now and on the trail shifting is normal again. Yes, its possible I bent the cog somehow but left the chain operational. (BTW, Im 175lbs and ride XC.)
    Otherwise, this cassette arrived bent; a fault of manufacturing I cannot prove because I've used the item. Bummer.

      Gives a wider gear range if you're running a 1x drivetrain. I'm running a 36t N/W chainring with this on my 26er.

        Comments about SRAM PG-990 9 Speed Cassette:

        Bought to replace my XT 9spd cassette. Liked the look of the red spider cage holding the cogs, and the fact the spider holds 5 gears, not just like lesser models. Shifting flowed seamlessly with my Shimano XT/XTR drivetrain. The price was right, and I've been impressed with the longevity so far as well. (About 2 seasons so far.)

          I have tried more expensive cassettes...XTR stuff...My whole drivetrain is XTR...but the cassettes just don't last for money....I tried one of these years ago...And I get the same performance for half the cost and the bling of added colour..This cassette is a win win.......

          Holding Strong for the last four years now, had an issue with the same model previously but that was because of a miss-shift on my part where two teeth snapped off of one of the rings. So far this one is holding on very well...

            I bought this cassette because it was a decent price at a decent weight and it is of good quality. also the red matches my bikes color scheme so it looks great. seems to run well, I can't complain.. I think everyone is getting away from 9 speed though

                I've moved this Cassette around to 3 different bikes now, it's always worked great for me never missing a beat.

                I'm sure you could spend a bit more and save some weight, but why bother, this works great!

                  Nice, light, functional, and relatively durable.

                        Jenson is my number one source for these rear cassettes. I'd pay more than twice this from my LBS. I always buy two at a time in case the sale ends, but Jenson just seems to keep them on sale year after year.
