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.
Front Derailleur
The electronic front derailleur is designed for 2x road drivetrains, giving riders the wider gear range expected from a modern road bike. It manages shifts between the front chainrings electronically, helping deliver smoother and more consistent front shifting when properly set up.
A 2x setup is well suited to road riding because it gives riders closer gear steps and a broader overall range, making it suitable for flatter roads, fast group rides and hillier routes.
