SRAM PG-980 9 Speed Cassette
The SRAM PG980 cassette might be the best performance value out there. Steel cassette cogs on a black anodized alloy spider provide lightweight and efficient performance. The PowerGlide II cassette cogs are the quietest to date. The SRAM PG980 cassette is a wonderful value for the performance oriented mountain biker on a budget.
Please Note: This cassette requires the Park FR-5 for installation and removal.
