Trek SRAM AXS Extension Cord for TQ E-Systems

The extension cord is an optional item for the SRAM AXS drivetrain, powering the derailleur from the e-system battery instead of a separate AXS battery.
Integrating into the derailleurs AXS battery port, the cord routs through the bicycle frame into the e-system drive unit.

Features
- Works with any AXS derailleur
- Powers derailleur by main e-system battery
