Frequently Asked Questions
What fits with LTWOO ERX Shifter (ST-ER1202-2L-C)?
LTWOO ERX Shifter (ST-ER1202-2L-C) is compatible with brake calipers, cassettes, rear derailleurs, front derailleurs 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 Shifter (ST-ER1202-2L-C)?
No, LTWOO ERX Shifter (ST-ER1202-2L-C) 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 the mounting standard of LTWOO ERX Shifter (ST-ER1202-2L-C) affect drivetrain compatibility?
The mounting standard (such as drop_bars) primarily determines how the part attaches to the bike frame or handlebars. It does not directly affect the mechanical shifting compatibility, as long as the speed and brand standards match.
