sram xg999 cassette 9 speed   SRAM XG999 Cassette 9 Speed

SRAM mainly known for their drivetrain components pushes the bar once again by taking the SRAM cassette that is apart of the XX groupset and making it available in 9 speed guise. Seven of the cogs are CNC machined together, which was put together by a block of billet steel on the XG999 cassette. The SRAM XG999 Cassette 9 Speed is said to weigh 175 grams for the 11-32 cassette, but with SRAM a high retail price does come, with the SRAM XG999 Cassette 9 Speed retailing at $300.
