No mixed messaging or compromises here. The PG-720 cassette was built with only one purpose in mind - exploiting gravity to its fullest lap after lap. This downhill-optimized cassette gives you gear steps that give each shift more purpose. It&';s a full-on dedicated SRAM 1x(TM) cassette for gravity that lets you keep some money for a lift ticket.
