SRAM X4 Rear Derailleur Compatibility Guide

Quick Verdict

SRAM X4 Rear Derailleur is a SRAM rear derailleur. It is a 7-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.

Shiftingcable

How this list is built: a part is listed only when we hold the specification that decides the pairing for bothparts and those specifications match: the freehub body for a cassette and a wheel, the mounting interface for a chainring and a crankset, and so on. Each card shows exactly what was compared. Where we do not hold that specification the part is left out rather than assumed to fit, so this list is deliberately incomplete rather than speculative. Always confirm against the manufacturer’s own compatibility documentation before buying.

Frequently Asked Questions

What fits SRAM X4 Rear Derailleur?

On this page we list shifters that drive this derailleur, cassettes this derailleur can wrap. 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 X4 Rear Derailleur?

No. SRAM X4 Rear Derailleur is a 7-speed component and needs a 7-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 X4 Rear Derailleur work with electronic shifting like Di2 or AXS?

No. SRAM X4 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.
