SRAM Powerglide II PG-730 Cassette

The SRAM Powerglide II PG-730 cassette is a 7-speed cassette designed for mountain biking, with the PG system and a 12-32-tooth range. The supplier presents it as more reliable and durable, with tooth profiles and shift ramps for fast, precise shifting. Before ordering, check that your hub is PG 7-speed.

The finish is silver and the range is 12-32 teeth, with seven sprockets: 12, 14, 16, 18, 21, 26 and 32. Choose your gearing according to the terrain: smaller sprockets for speed, larger ones for steep climbs. With seven sprockets, the jump between gears is more pronounced than on a cassette with more speeds.

Founded in Chicago in 1987 by Stan Day and a group of cycling enthusiasts, SRAM is still based in the US city today. It makes drivetrains and brakes for road, gravel and mountain bikes. Its story began with a single product: Grip Shift, the shifter that lets riders change gear by twisting the grip.
