L-TWOO FAQ
How do I perform the initial setup and adjustment?
After installation, pair the components if required, install the compatible cassette and chain, and adjust the derailleur according to the manufacturer's instructions. Fine adjustment may be required to achieve smooth and accurate shifting.
How do I update the firmware?
Firmware updates can usually be completed through the compatible APP. Make sure the battery level is sufficient and keep your device connected during the update. Do not interrupt the update process.
How do I know if an L-TWOO groupset is compatible with my bike?
Before purchasing, please check your bike type, frame compatibility, brake type, cassette, freehub body, and axle standard. You can also send us your bike model and current drivetrain specifications for a compatibility check.
Which L-TWOO groupset is suitable for my bike: eR7, eRX, GRT or eGR?
eR7 and eRX are mainly designed for road bikes. GRT is designed for gravel and all-road riding. eGR is designed for gravel and off-road applications. Please choose the model based on your bike type, riding style, and required drivetrain configuration.
What is the difference between wireless and semi-wireless L-TWOO groupsets?
Wireless systems communicate between components without shift cables, providing a cleaner setup. Semi-wireless systems may use wireless communication between selected components while other parts remain connected by wires. The exact configuration depends on the specific model.
Which L-TWOO APP should I use, and how do I connect my groupset?
Please use the official APP specified for your L-TWOO groupset model. The APP can be used for system connection, firmware updates, button configuration, and other supported settings. Connection instructions may vary depending on the model.
Are your products genuine?
Yes. All products are genuine and sourced directly from manufacturers or authorized suppliers.
Will I have to pay import duties or taxes?
Import duties and taxes are included for destinations listed in our shipping policy. See the policy for destination details and exceptions.
Do L-TWOO electronic groupsets require professional installation?
Professional installation is recommended, especially for hydraulic brake systems and electronic shifting systems. Correct installation and adjustment can help ensure proper shifting and braking performance.
Which brake oil should I use for L-TWOO hydraulic brakes?
Please use the brake fluid specified by L-TWOO for your particular model. Do not mix different types of brake fluid. If you are unsure, contact us with your exact groupset model before adding or replacing brake fluid.
What type of thru axle is compatible with my bike?
Thru axle compatibility depends on your bike frame and wheel standard. Please confirm your frame's front and rear axle specifications before purchasing.
Which cassette and freehub standards are compatible with the groupset?
Cassette compatibility depends on the specific L-TWOO groupset model, speed, derailleur capacity, and freehub body. Please check the product specifications or contact us with your current cassette and wheel hub information before purchasing.
How long does the battery last, and how do I charge it?
Battery life depends on the model, riding frequency, and usage conditions. Please charge the components using the recommended charging method and cable. Avoid using damaged chargers or charging equipment.
What should I do if the shifting is not working properly?
First, check the battery level, component connection, firmware version, derailleur alignment, and chain and cassette compatibility. If the problem continues, contact us with your order number, product model, and a short video showing the issue so we can assist you.
