New Cassette From SRAM

January 27, 2010

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…

From behind - the new XO hollow cassette

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.
