Sram Cassette PG720 Powerglide Downhill

Sram: 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, and two variants let you match either traditional HG, or new-school 7-speed dh-specific HG hubs. It's a full-on, dedicated SRAM 1x™ cassette for gravity that lets you keep some money for a lift ticket.FeaturesDownhill-optimised 7-speed cassettePart of the SRAM 1x™ DH drivetrain systemMost affordable full-featured 1x DH cassette on the marketCompatible with SRAM 11-speed chains and X01 DH drivetrainSplined driver body compatibleRemovable spacer for use with DH-specific 7-speed HG hubs SPECIFICATIONSSpeed: 7 Gearing: 11-25t Cog finish: Silver Technology: PG Cog sizes: 11-13-15-17-19-22-25 Drivetrain configuration: 1x Cassette size (max): 25 Cassette size (min): 11 Chain technology: 11-speed PowerChain Rear derailleur mount: MTB, Road, Road L, UDH
