Compatibility
SRAM RED eTap Rear Derailleur is a SRAM rear derailleur. It is a 11-speed component. It uses axs 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.

Frequently Asked Questions
What fits SRAM RED eTap Rear Derailleur?
On this page we list chains 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 RED eTap Rear Derailleur?
No. SRAM RED eTap Rear Derailleur is a 11-speed component and needs a 11-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.
