Frequently Asked Questions

What fits with LTWOO AX Rear Derailleur (RD-A1210-L-A)?

LTWOO AX Rear Derailleur (RD-A1210-L-A) is compatible with shifters, cassettes, cranksets, chains that match its technical standards. Most importantly, it requires matching 12-speed components.

Can I use a higher or lower speed chain with LTWOO AX Rear Derailleur (RD-A1210-L-A)?

No, LTWOO AX Rear Derailleur (RD-A1210-L-A) 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 LTWOO AX Rear Derailleur (RD-A1210-L-A) 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.
