Enjoy the same reliable, lightweight performance that SRAM's BlackBox racers enjoy. The SRAM PG990 9 Sp 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 they're a great upgrade for any 9 speed bike on the market.
