SRAM Cassette PG-720 11-25 7 speed: 7SPD 11-25T

Sram:

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. It’s a full-on, dedicated SRAM 1x™ cassette for gravity that lets you keep some money for a lift ticket. GX DH — Get Some.
