Know before you buy
No, the XG-1290 requires an XDR driver body. If your current wheelset uses a standard HG freehub body, you will need to purchase an XDR-compatible driver body from your wheel manufacturer to install this cassette.
The XG-1290 is specifically engineered for SRAM’s 12-speed wireless electronic shifting systems. It is not compatible with mechanical drivetrains.
The 10-tooth cog allows for a wider gear range without sacrificing the tight, gradual steps between gears that you need for efficient pedaling. It enables you to use a smaller chainring setup while maintaining high-end speed.
The one-piece machined steel X-Dome design is incredibly stiff and lightweight, which helps maintain precise shifting performance over time. Because it is a single unit, it is also easier to clean and maintain compared to cassettes with individual cogs.
The right choice depends on your local terrain and riding style. Choose the 10-26 or 10-28 for flatter, faster rides where you want minimal jumps between gears, or opt for the 10-33 or 10-36 if you need extra range for climbing steep gradients.
