UPGRADED
The new version of the ERX features significant performance improvements while retaining the previous power supply logic, compatible with 10-12 speeds.
ELECTRONIC SHIFTER
The ergonomic design and optimized button feel of the electronic shifter are a boon for riders. The wider grip ensures comfort during long rides, while the clearer button feedback makes it suitable for harsh conditions like strong winds and muddy terrain. Each press provides distinct feedback and precise shifting performance.
Electronic FD
The ERX features an upgraded electronic front derailleur.
It uses a LTWOO selfmade motor, providing powerful drive for faster shifting.
The guide plate structure has been significantly optimized for smoother gear changes.
It also includes a Type-C charging port for easier charging.
The aerodynamic design reduces wind resistance by minimizing the frontal area.
Electronic RD
The rear derailleur has removed the magnetic charging port and adjusted the shifting logic and programming.
It now uses asynchronous multi-speed shifting and over-travel methods, improving stability during operation, reducing energy consumption, and extending battery life.
INTEGRATED CALIPER
The caliper features an integrated design, eliminating the mounting screws used in split designs.
This reduces weight while enhancing overall rigidity.
