No mixed messaging or compromises here. The GX DH cassette was built with only one purpose in mind exploiting gravity to its fullest lap after lap. This downhill-optimized 7-speed cassette gives you gear steps that give each shift more purpose, and its compact design allows more spoke clearance. Its a full-on, dedicated SRAM 1x cassette for gravity that lets you keep some money for a lift ticket. GX DH Get Some.
