The performance of the SRAM PG-1130 11 speed cassette is optimised by its tooth profile and shift ramp design for quick and positive index shifting. It shifts efficiently and positively in all high performance situations. The updated design features a semi-spidered construction for a maximum stiffness to weight ratio. This road bike cassette is compatible with PC 1170 and PC 1130 11 speed chains. With many of the world’s top teams ‘Making the Leap’ to SRAM, there is little doubt that wins at the Classics, Grand Tours, Ironman™, and Cross Worlds were due in part to the lightest, most efficient, and ergonomic road componentry ever made.
