Shimano Di2 SM-EW90 Junction Box A

Expand your secondary shift options with the Shimano Di2 SM-EW90 Junction Box.

Available in a 3 or 5 port version, the SM-EW90 is the gateway to the ultimate Di2 expansion.

Features:

  • Expands Di2 systems to accomodate secondary shift buttons
  • 3 or 5 port version
  • Acts as a charging port for Shimano's internal SM-BTR2 Di2 battery (not included).
