Can I use my existing eTap AXS 1x crankset with the XPLR rear derailleur and 10-44T cassette?

Yes, all of our 1x road/gravel DUB cranksets are compatible with XPLR rear derailleurs and cassettes.

For more details on the compatibility of our SRAM AXS components, check out the AXS Components Compatibility Map.
For the compatibility of the mechanical version of the XPLR rear derailleur, you can instead have a look at the 1x12 Road Compatibility Map.
