3.2. Component Installation
Installation of the WHEELTOP EDS TX-RA7000 groupset requires basic bicycle mechanic knowledge. If you are unsure, please consult a professional bicycle mechanic.
- Mount Shifters: Securely mount the left and right shifters to your handlebars. The ergonomic design ensures a comfortable grip and clear shift feel.
- Install Derailleurs: Attach the front and rear derailleurs to your bike frame. Ensure proper alignment with the chainrings and cassette.
- Brake System: For hydraulic disc brake models (TX-RA7000-GS), install the oil-hydraulic disc brake clamps. These CNC one-piece molded clamps offer high air tightness and are compatible with 140mm or 160mm discs.
- Chain Installation: Install your bicycle chain, ensuring it is compatible with 7-13 speed systems.

3.3. Wireless Pairing and Adjustment
Refer to the detailed pairing instructions provided with your groupset for initial setup. The system allows for variable speed mode selection and precise adjustment for optimal shifting performance across 7 to 13-speed freewheels (within 37T).
4. Operating Instructions
4.1. Shifting Gears
The EDS TX-RA7000 groupset offers intuitive electronic shifting. Use the left shifter for the front derailleur (1s/2s) and the right shifter for the rear derailleur (7s~13s). The carbon fiber levers provide an ergonomic feel and precise feedback for each shift.

4.2. Braking
For models equipped with hydraulic disc brakes, apply pressure to the brake levers to engage the calipers. The CNC one-piece molded calipers, featuring ceramic pistons, provide strong and consistent braking power with good heat resistance.
5. Maintenance
5.1. Cleaning and Care
The EDS TX-RA7000 components are designed with water-repellent properties, making them suitable for riding in light rain. However, avoid prolonged exposure to heavy rain or submersion to prevent potential damage to the electronic components.
Figure 5.1: Water repellent feature demonstrated on the derailleurs.
Regularly clean the derailleurs, shifters, and brake calipers with a damp cloth. Avoid using high-pressure washers directly on electronic parts.
5.2. Guide Wheel Maintenance
The resin guide wheels are designed for smooth and durable operation, reducing chain wear. Periodically inspect the guide wheels for any debris or excessive wear. Clean them as needed to maintain optimal chain transmission.

5.3. Battery Care
Charge the derailleurs regularly, especially if the bike will be stored for an extended period. Avoid completely draining the batteries to prolong their lifespan.
6. Troubleshooting
This section addresses common issues you might encounter with your WHEELTOP EDS TX-RA7000 groupset. For more complex problems, please contact customer support or a certified mechanic.
- Shifting Issues: If shifting is inconsistent or unresponsive, check battery levels first. Ensure derailleurs are fully charged. Re-pair the components if necessary. Verify that the derailleur limits are correctly set and that the chain is clean and lubricated.
- Brake Performance: If disc brakes feel spongy or lack power, check for air in the hydraulic lines or worn brake pads. Ensure discs are clean and free of oil.
- No Power: If a component does not power on, ensure it is fully charged. Check the charging cable and power source.
