SRAM PG-990 Cassette Item # 855490
Description
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.
