The advantages of the L-TWOO ER9 electronic shifting for road bikes（cycletrack model river）

The advantages of the L - TWOO ER9 electronic shifting for road bikes are as follows:

Affordable price: Compared with some high - end electronic shifting systems of well - known international brands, L - TWOO ER9 is more budget - friendly. It allows riders to enjoy the convenience of electronic shifting at a relatively low cost, making it an attractive option for those with limited budgets.

Multi - speed adaptability: It can simultaneously adapt to 10/11/12 - speed systems, which is a significant feature. This wide compatibility enables it to match a variety of cassettes and drivetrain setups, providing more flexibility for riders when upgrading or replacing components.
Component adaptability: Both the front and rear derailleurs have single - gear fine - tuning functions. This allows for subtle adjustments to each sprocket, enabling it to be compatible with the vast majority of cassettes and chainrings on the market. It solves the problem of inaccurate shifting caused by tolerances between different brands.

Button - based shifting: Each shifter has two shifting buttons that can be controlled by a single finger for gear changes. The mouse - like pressing feel of the shifting buttons provides riders with good feedback on the shifting status. Moreover, the buttons support custom function settings through the app, allowing riders to personalize the operation according to their preferences.
Simplified adjustment: It simplifies the cumbersome shifting adjustment process. Riders can complete the operation through a mobile phone, which is convenient and intuitive.

Lightweight options: The shifter is available in carbon fiber material (ERX, 225g), which ensures that it is light enough. This is especially suitable for professional riders who have strict requirements for the overall weight of the bike. Even the aluminum lever version (ER9, 245g) offers a relatively lightweight solution while maintaining cost - effectiveness.
Anti - collision design: The rear derailleur is equipped with a unique anti - collision structure design. When encountering strong external forces (such as collisions), it can automatically disconnect from the motor to ensure the safety of the motor.

Remote upgrade: The rear derailleur has a chip that supports app connection for remote program upgrades. Through continuous version iterations, the shifting speed and accuracy of the rear derailleur can be continuously improved.

Long - lasting power: The seat post battery, which powers the front and rear derailleurs, contains two lithium - ion batteries. In a fully charged state, it can support approximately 800 - 1000 kilometers of riding, reducing the frequency of charging and ensuring long - distance riding without concerns about power shortages.
