SRAM PG-990 9 Speed Cassette

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

Surprisingly weak
Over the years I've purchased many MTB components from JensonUSA. Their service and delivery has always been perfect. This has been the only item I have found to be less than.

The '10 adds one...
The '10 adds one more cog to the carrier than the previous year's version and no improvements seem to have been made to the '11. They reduced the number of individual parts to just the carrier, the 3 cogs (with spacer built in) and the lockring. Gone are the individual cogs that require a spacer between them.This is a hot price for a quality cassette for use with high end hubs with alloy freehub bodies. If you have a steel freehub, you can get away with a cheaper and heavier cassette. Don't waste your money on an '11 when you can get the '10 version for much cheaper.I find no compelling reason to upgrade to 10spd yet, so I might just get another to keep in stock. This seems to be as good as it gets without going to X-glide teeth shape profiling or milling it out of a single block of steel like the XG cassettes. I hear the XG cassettes last 2-3 times as long as this and shift far smoother, but when these are a 1/3 to 1/4 of the price, I'm content with buying these and replacing them more often.

Gears to get you up the hill
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.)

GEAR UP
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

Improved gear range for 1x setups.
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.

smooth
shifts smooth and treads lightly on your hub body. I've ran this cassette on my bike for the last 5 years and have zero issues. It's a great deal if you can get it on sale.

Cassette that Rocks with Performance
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.......

Good value
Reasonable performer at a great price. Not durable enough for heavy off-road use; will show significant wear in under 1000 trail miles. Perfect, however, for a commuter bike on our steep hills.

CONS: Not Durable
