LTWOO eR9 Electronic Road Groupset
The LTWOO eR9 is an electronic road groupset designed for riders who want the benefits of electronic shifting without moving into the highest price brackets of more established drivetrain brands.
Built for performance road bikes, the eR9 combines electronic gear changes with hydraulic disc braking, giving riders a cleaner cockpit, more consistent shifting and confident braking control. It is best suited to road, endurance and all-road builds where riders want modern technology, good usability and strong value.
The eR9 is a practical option for riders who want to experience electronic shifting on a modern road bike, while keeping the overall build cost sensible.
Shifters
The eR9 dual-control shifters combine electronic shifting with hydraulic brake control. The shift buttons are designed to give simple, direct gear changes, while the brake levers provide control from both the hoods and drops.
Because the gear shifting is electronic, there are no traditional mechanical gear cables to stretch, wear or adjust over time. This helps keep the setup cleaner and can reduce the need for regular indexing once the system is correctly installed and configured.
