Frequently Asked Questions

What fits with SRAM XX1 X-HORIZON Rear Derailleur?

SRAM XX1 X-HORIZON Rear Derailleur is compatible with cranksets, shifters, chains, cassettes that match its technical standards. Most importantly, it requires matching 11-speed components.

Can I use a higher or lower speed chain with SRAM XX1 X-HORIZON Rear Derailleur?

No, SRAM XX1 X-HORIZON Rear Derailleur requires a 11-speed chain. Chains for different speeds have different external widths and internal profiles, which will cause poor shifting or mechanical interference.

Does this SRAM XX1 X-HORIZON 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.

Can I mix SRAM XX1 X-HORIZON Rear Derailleur with Road components?

While some mechanical standards (like cassette spacing at certain speeds) may overlap, SRAM XX1 X-HORIZON Rear Derailleur is optimized for MTB use. Mixing with Road parts often fails due to differing pull ratios and chainlines.
