Shimano External battery mount XTR Di2 Electric Wire

The Battery Case SM-BTC1 mounts the SM-BTR2 on the bikeś bottle cage bosses. The six e-tube wiring ports for convenient cabling. The mount acts as a junction “B” as well.

Shimano’s XTR M9050 gears uses the same E-tube-platform which is also introduced in the Di2-groups for racing bikes. E-tube is programmable and customisable, and you could also expand and add other systems.
The cabling is available in a variety of lengths; for every bike an ideal cabling. Unlike standard cables and housing, the wires are not affected by the trail and weather providing optimal performance at all times.
