Frequently Asked Questions

What fits with SRAM X4 Rear Derailleur?

SRAM X4 Rear Derailleur is compatible with shifters, cassettes, chains that match its technical standards. Most importantly, it requires matching 7-speed components.

Can I use a higher or lower speed chain with SRAM X4 Rear Derailleur?

No, SRAM X4 Rear Derailleur requires a 7-speed chain. Chains for different speeds have different external widths and internal profiles, which will cause poor shifting or mechanical interference.

Does this SRAM X4 Rear Derailleur work with electronic shifting like Di2 or AXS?

No, this is a mechanical cable-actuated component. Electronic systems use internal motors and proprietary signals that are physically and electrically incompatible with mechanical components.
