SM-BCR2

Brand: Shimano

Charger for 11-speed Di2 internal batteries, plugged into the cockpit junction A: the battery stays in the frame. It feeds the SM-BTR2, BT-DN110 and BT-DN110-A in about 1.5 hours from a USB mains adapter, or about 3 hours from a computer USB port. It also acts as an E-TUBE PROJECT interface, which Shimano calls a « PC linkage device with limited function »: it handles settings and updates, with fewer functions than the SM-PCE1 box. Its charging cord is included.
