L-TWOO EGR RD-EG1201-M-A – electronic rear derailleur, 10–12-speed
The L-TWOO EGR RD-EG1301-M-A is an electronic rear derailleur for 10-, 11- and 12-speed gear systems. It enables wireless electronic shifting, and the aluminum alloy housing provides a good balance between rigidity, durability and weight.
The derailleur is equipped with a Tension Damping system, which uses a mechanical damper to increase resistance to unidirectional cage movement, helping to reduce vibration and chain skipping. The Impact Rebound system allows the derailleur to quickly return to position after an impact.
