Frequently Asked Questions
What fits with LTWOO ERX Front Derailleur (FD-ER1204)?
LTWOO ERX Front Derailleur (FD-ER1204) is compatible with frames, cranksets, chains, shifters that match its technical standards. Most importantly, it requires matching 12-speed components.
Can I use a higher or lower speed chain with LTWOO ERX Front Derailleur (FD-ER1204)?
