Compatibility
SRAM Apex XPLR Rear Derailleur is a SRAM rear derailleur. It is a 12-speed component. It uses Cable shifting. Everything listed below was matched on a specification we hold for both parts: the interface each pairing actually depends on, such as freehub body, speed count, actuation or mounting standard. Where we could not verify that interface, the part is left out rather than assumed to fit.
Apex XPLR Groupset5
A groupset is designed and tested as one system, so these are the most reliable match. Other compatible parts are listed below.

Frequently Asked Questions
What fits SRAM Apex XPLR Rear Derailleur?
On this page we list chains for this derailleur, shifters that drive this derailleur, cassettes for this derailleur. Each listing was matched on a specification we hold for both parts; anything we could not verify is omitted rather than assumed to fit.
Can I use a higher or lower speed chain with SRAM Apex XPLR Rear Derailleur?
No. SRAM Apex XPLR Rear Derailleur is a 12-speed component and needs a 12-speed chain. Chains for different speed counts have different external widths and inner-plate profiles, which causes poor shifting or interference with the neighbouring sprockets.
Does SRAM Apex XPLR Rear Derailleur work with electronic shifting like Di2 or AXS?
No. SRAM Apex XPLR Rear Derailleur is mechanical, cable-actuated. Electronic groups use internal motors and proprietary signalling, so there is no mechanical or electrical path between the two.
