AXS Extension Cord for Bosch BES3 - 880mm

The SRAM AXS Extension Cord for Bosch BES3 - 880mm connects the SRAM Eagle Powertrain system directly to the main eBike battery, eliminating the need for a separate AXS derailleur battery. This clean and integrated setup helps simplify power management and ensures consistent performance on every ride.

Designed to route internally through the frame, the 880mm length provides flexibility for a wide range of frame sizes and geometries while maintaining a tidy and protected cable path. This extension cord connects directly to the derailleur’s AXS battery port and the SRAM Drive Unit (DU), making it a straightforward upgrade for riders who want a fully unified power source.
