Probably the most impressive part of SRAM’s new XX groupset is the cassette which is hewn from a solid block of steel. Which is lovely, but what if you want to run 9 speed rather than 10?
SRAM are happy to fulfill your desires…
The revolutionary machined design of the XG999 cassette uses the same grueling manufacturing techniques that produced the XX as well as the PowerDome road cassette.
With this XG999 cassette, seven of the cogs are CNC-machined together out of a single block of billet steel, creating an incredibly lightweight, precise, and strong cassette.
The open design aids in mud clearance, giving you cleaner shifting performance and longer component life.

175g! Shimano’s XTR cassette is a claimed 224g for comparison.
Jesus! It’s a nice Cassette that is all- I think it’s odd that Sram are being complained at because other peoples freehubs are made of soft cheese.
My KCNC is lighter, stronger, far more pimp, and cheaper. So what if it’s only 9 speed.
I dont think the “open design” will aid mud clearance. The large sprocket is not as open as an XT cassette. It looks to me that muck coming in from the outside/chain area may well get trapped inside.
…get over it guys..it’s pimpy, different and pushing the boundaries weight wise for 9speed. Sram should be given credit for this..it’s not like Shimano has had any decent competition before they came along.
As for price merlin are already knocking a third off XX..so may become available at a more sensible price soon
