Overview

The L-TWOO Road Electronic Shifting Groupset for eR9 Series brings responsive electronic shifting and hydraulic disc braking to performance road bicycles. It supports 2x drivetrains with 10, 11 or 12-speed rear cassettes. 

Wireless Lever Operation: The shift levers use replaceable CR2032 batteries to transmit commands without shift cables. Adjustable reach helps riders refine lever positioning for improved comfort and control.

Wide Drivetrain Compatibility: The electronic rear derailleur accommodates 10–12-speed systems with cassette sprockets from 11T to 32T. The front derailleur supports chainrings up to 56T and a total capacity of 16T.

Controlled Hydraulic Braking: Flat-mount hydraulic disc calipers use mineral oil and support 140 mm or 160 mm rotors. The system provides smooth modulation and dependable braking for fast descents and changing road conditions.

L-TWOO Road Electronic Shifting Groupset for eR9 Series combines configurable shifting, broad compatibility and hydraulic control for a refined road-bike setup.
