Lightweight and good high speed pedaling.
Took a while to get new wheels to set up with this cassette, due to problems getting a new set of carbon wheels.The cassette worked beautifully for riding XC and long-distance fast rides. The 9 sprocket is very nice to have and works as advertised for higher speed runs towards trailheads.It feels pretty light, all set up, but was not looking for weight savings, so haven't weighed it.Using SRAM GX groupset. Initally the shifting was good. However, after the bike store changed my cables, the shifting has been off. The shop is blaming the cassette, but I don't buy that excuse.300+ miles - Very good so far.

Tuff but worth it.
I see some people say it doesn't work. It just takes some patience and knowing when to adjust b screw in or out. Once set up great range.

Beautiful, but poor shifting quality
I installed this on my XX1 Eagle AXS system and spent an hour trying to dial in the b-adjuster and shifting. The cassette is off on spacing somewhere in the design as it is near impossible to get good clean shifting, and to get bad shifting with AXS is hard to do. The Cassette also has poor ramping and drops chains when spinning backward. I tried 3 different spacers and adjusted my crank and front chainring to no avail. This is a poorly designed product and that is too bad because it is from a reputable manufacturer of parts. I have built 20+ custom bikes and never had a cassette this bad. Until they improve the design, this is not a product worth the cost.
