I have a gravel bike which has a sram red xplr 10-46 with 38T chainring. When I bike pack I replace the rear derailer with Eagle XX SL transmission rear derailer and chain over the xplr 38T threaded chainring - it works great. I want replace the 38T with a 34T Eagle xxsl threaded chainring for mountain bike packing I’m planning. The threads are they the same? What offset is required?

SRAM does not consider the MTB thread-on chainrings compatible with the Red E1 XPLR Power Meter Spider.

How do I know what chainring offset I need for the SRAM XX SL Eagle T-Type Thread Mount Chainring?

This chainring is available in both 0 mm and 3 mm offsets. This page will help you determine what offset you need: What Chainring Offset for SRAM Eagle T-Type Cranksets and Power Meters?
