Frequently Asked Questions

What fits with SRAM Eagle S100 Derailleur?

SRAM Eagle S100 Derailleur is compatible with shifters, cassettes, chains, cranksets that match its technical standards. Most importantly, it requires matching 12-speed components.

Can I use a higher or lower speed chain with SRAM Eagle S100 Derailleur?

No, SRAM Eagle S100 Derailleur requires a 12-speed chain. Chains for different speeds have different external widths and internal profiles, which will cause poor shifting or mechanical interference.

Does this SRAM Eagle S100 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 Eagle S100 Derailleur with Road components?

While some mechanical standards (like cassette spacing at certain speeds) may overlap, SRAM Eagle S100 Derailleur is optimized for MTB use. Mixing with Road parts often fails due to differing pull ratios and chainlines.
