Race-bred electronic shifting at an accessible price

The L-TWOO eRX is the brand's flagship wireless electronic road groupset: one press of a button and the shift is fast and precise – in rain, wind and mud alike. The carbon-lever shifters, the new-generation front and rear derailleurs and the integrated hydraulic disc brakes form a light, unified system.

Works with 10, 11 and 12-speed cassettes, and setup and updates are easy with the L-TWOO APP.

The set includes: shift/brake levers (left/right), front and rear derailleur, front and rear caliper, battery, power cables, charging cable. Crankset, chain, cassette and brake rotors are not included.

L-TWOO eRX 2x12 Electronic Road Bike Groupset – Ergonomic wireless shift/brake levers

Ergonomic wireless shift/brake levers

The lever shape and button feel have been redesigned. The wider grip stays comfortable on long rides, and the clear button click gives reliable feedback even in strong wind and muddy conditions.

Every press delivers a precise, fast shift, while the carbon brake lever is light and stiff.

L-TWOO eRX 2x12 Electronic Road Bike Groupset – New rear derailleur software – more stable shifting, longer battery life

New rear derailleur software – more stable shifting, longer battery life

The rear derailleur's software and shift logic have been updated: it uses asynchronous multi-shift and over-travel technology for more stable operation, lower energy use and longer battery life.

The system is compatible with 10, 11 and 12-speed drivetrains, and fine-tuning can also be done in the L-TWOO APP.

L-TWOO eRX 2x12 Electronic Road Bike Groupset – Stronger front derailleur and integrated hydraulic caliper

Stronger front derailleur and integrated hydraulic caliper

The front derailleur is driven by L-TWOO's in-house motor for stronger, faster shifts. The cage design has been significantly optimised for smoother changes, and the aerodynamic shape reduces drag. Charging is via a Type-C port.

The one-piece integrated caliper drops the mounting bolts of split designs, making it lighter and stiffer, and its better heat dissipation gives consistent braking on long descents.
