Take your downhill performance to the next level with the SRAM PG-720 Powerglide Downhill Cassette, purpose-built for gravity riders who demand precision, strength, and consistency on every descent. Designed exclusively for 1x DH drivetrain systems, this 7-speed cassette delivers perfectly spaced gear ratios to optimise control, acceleration, and chain retention when the trail gets steep and fast.

Whether you’re attacking technical rock gardens or boosting big drops, this cassette keeps your drivetrain performing flawlessly, lap after lap.
