Go ahead and count 'em.
The new XG-1190 Cassette arguably holds the responsibility of being the defining component of SRAM's new Red 22 groupset. It carries over the beautiful engineering that defined the super light, silent, and precise XG-1090, with the addition of the 16T cog neatly tucked into the cassette's profile. This 16T is now the linking cog that delivers better cadence control as you hover within the middle block of the 11-speed cassette.
In order to fully understand exactly where this new XG-1190 comes from, we must first step back and examine the roots of the Red Cassette family. SRAM's original Red Cassette was an exceptional drivetrain component with only one downside: when installed on a deep carbon wheel or ridden amongst a group of riders on Red, it created a resounding cacophony that drowned out even the most concentrated thoughts. There was nothing inherently wrong with this cassette, known officially as the OG-1090. It was lightweight, it shifted crisply, and was resistant to wear over the course of prolonged use. But it was noisy due to its Powerdome construction, which acted like a phonograph that reverberated drivetrain clatter from the freehub and chain. And thus the SRAM Red XG-1090 X-Dome Cassette was born.
With the latest Powerdome X construction, the middle nine cogs on the new XG-1190 are machined from a single block of high-grade tool steel -- a technique similar to that of their popular XG-1099 mountain cassette. The cassette is then finished with two carefully machined aluminum cogs. The largest cog has a machined backplate to increase strength and improve stiffness—a definite advantage if this is your punchy, last-resort climbing gear. The whole cassette requires a machining process so complex and precise that each piece takes around seventy minutes to produce. But the final product is more than worth the effort—it is a hollow, inspiring piece of engineering that is both stiff and exceptionally lightweight. And excess noise is effectively dissipated, leaving you with nothing but the smooth, crisp, and reliable shifting SRAM Red is best known for.
To further reduce noise, SRAM also fitted an elastomer StealthRing between each cog to engage, dampen, and thereby eliminate any excess chatter from the chain. The rings are shaped to mesh with SRAM's new PC-Red 22 chain, and they do not compromise power transfer.
SRAM improved exactly where it needed, and the new SRAM Red XG-1190 X-Dome Cassette is a true upgrade to its predecessors while still remaining faithful to the SRAM Red pedigree that provides the lightest and arguably best-climbing groupset on the market. For smooth and flawless shifting across SRAM's machined X-Glide cassette teeth, and to run a drivetrain perfectly optimized for quiet operation with the StealthRings, SRAM recommends using its PC-Red 22 Chain. The cassette also includes an anodized, laser-etched aluminum lockring. Please note that the XG-1190 Cassette will only fit 11-speed compatible hub/freehub bodies.
