The heart of the PG-990 cassette is its CNC machined aluminum spider. The five arm alloy spider provides a rigid foundation for our PowerGlide™ cogs, we are very confident in claiming this to be the strongest 9-speed cassette available. Included in this package is a precision forged 7000 series aluminum lock ring. With five Select color options to choose from the PG-990 is a great way to customize your ride.
