The SRAM PG-1170 Cassette offers gearing options needed for challenging climbs, fast descents, sprints, and everything in between.


WiFLi - SRAM's WiFLi technology accommodates a wider range of gears than a standard short-cage road derailleur. Compared to a triple chainring setup, it provides faster shifts and significant weight savings.


Cassette design for high shifting performance with a quieter chain/cassette combination.

Semi-spidered design: light, strong, efficient.
