The SRAM Red XG-1290 E1 12-Speed Cassette is designed for competitive cyclists seeking the pinnacle of shifting performance and gear range. Its primary benefit is exceptionally smooth and rapid gear changes, enabled by precise shift ramps and a wide selection of gear ratios. A potential caveat is its reliance on an XDR driver body for compatibility.

An XDR driver body is a specific freehub body standard developed by SRAM for their 10-tooth cog cassettes. It is wider than standard HG freehubs and requires a specific end cap for installation.
No, this SRAM Red XG-1290 E1 cassette is designed for 12-speed SRAM electronic drivetrains and is not compatible with Shimano or Campagnolo drivetrains.
The SRAM Red XG-1290 E1 cassette is available in 10-28T, 10-30T, 10-33T, and 10-36T configurations.
This E1 generation cassette is designed for current 12-speed SRAM AXS electronic systems. Compatibility with older mechanical or 11-speed groupsets is not supported.
Consider your typical riding terrain. For predominantly flat or fast riding, a smaller range like 10-28T might suffice. For hilly or mountainous terrain, a wider range like 10-33T or 10-36T will provide more climbing ease.
The weight varies slightly by configuration, but the X-DOME design contributes to a competitive weight for a 12-speed cassette. Specific weights can be found in detailed product specifications.
Ensure the derailleur hanger is straight and the derailleur is properly adjusted. Verify the chain is clean and lubricated. Check that the XDR driver body is correctly installed and that the cassette lockring is tightened.
This can indicate wear on the cassette or chain, or incorrect adjustment. Inspect both components for wear. Re-adjust the derailleur indexing, ensuring the B-tension screw is set appropriately for the chosen cassette range.
Check for proper torque on the cassette lockring. Ensure the chain is properly lubricated and free of debris. Inspect for any bent teeth on the cassette or damaged chain links.
Setup:
Installation requires a compatible XDR driver body on your rear wheel. The cassette is installed using a standard cassette lockring tool. Ensure the lockring is torqued to manufacturer specifications.
Compatibility:
This cassette is designed for 12-speed SRAM electronic drivetrains. It is only compatible with SRAM XDR or XD driver bodies. It will not function correctly with standard Shimano HG or Campagnolo freehub bodies.
Care:
Regular cleaning of the cassette is essential for optimal performance. Use a degreaser and brush to remove dirt and grime from between the cogs. Keep the chain clean and lubricated. Inspect for any bent teeth or damage, especially after a crash.
