The SRAM PG-820 bike cassette’s performance is optimised for Mountain Bike use. The choice of materials, tooth profile, and shift ramp design will give you a more reliable, durable and efficient gearing system.

Extend the life of your cassette with the SunRace Service Kit, designed to replace worn-out sprockets without the need for a full cassette replacement. This cost-effective solution includes a lockring and three replacement sprockets, ideal for riders who wear out the lower gears first.
