Shimano Ultegra CS-6700

The CS-6700 is compatible with standard Shimano and SRAM 8, 9, and 10-speed freehub bodies. If you are currently running a 10-speed Shimano or SRAM drivetrain, this cassette will fit your existing hub without modification.

Yes, the Shimano Ultegra CS-6700 includes the necessary lockring. You will need a standard cassette lockring tool and a chain whip to install or remove it from your wheel.
