This is the Shimano Ultegra CS-6800 11-Speed Cassette. Using Hyperglide sprockets with revised tooth profiles, the CS-6800 11-speed cassette features reduced wear and lightning-quick shifts. Even under the most demanding gear changes you can expect improved shifting thanks to a rigid aluminum carrier to keep the cogs in check.

Hi I bought this is October of 2021 but just got around replacing my old cassette today. I noticed that the 4 smallest gears are bent and 2 of the gears have sawtooth teeth versus the typical rectangle. Any chance I can get a replacement? I can send you the defective set
