It has the same excellent qualities as its predecessor, only the colour is different. The eTAP XG-1190 cassette is the most advanced 11-speed cassette ever made. It is incredibly light, quiet and has unequivocal performance advantages. It has a StealthRing between every cog in the cluster, to reduce vibration and noise. The cutouts on the rear reduce weight and increase stiffness.
This cassette is one of the parts that make the drivetrain perfect. Combined with the new Sram eTAP rear derailleur, this cassette offers fast and quiet shifts so you're always in the right gear.
