LTWOO eRX Electronic Road Groupset
The LTWOO eRX is an electronic road groupset designed for riders who want the clean feel, fast response and adjustability of electronic shifting at a more accessible price point. Built for 2x road drivetrains and compatible with 10, 11 and 12-speed rear setups, it combines electronic shifting with hydraulic disc braking. The system uses carbon and aluminium construction to reduce weight where possible, while app connectivity allows riders to customise shifting behaviour and fine-tune the setup. It is best suited to performance road builds where precise shifting, modern braking and value are all important.
Rear Derailleur
The eRX rear derailleur is compatible with 10, 11 and 12-speed road drivetrains and supports cassette ranges up to 11-32T. The 2026 version has been updated to improve shifting precision and stability. It also supports asynchronous multi-speed shifting, allowing smoother movement across the cassette while helping manage power use. An optional oversized ceramic pulley is available for riders looking to further optimise drivetrain efficiency.
