Exactly as described

I needed this new external battery mount for my SM-BTR1 External Battery. This will provide Bluetooth wireless functionality with EW-WU101 ANT and Bluetooth Wireless Broadcast Module.

E-TUBE Bluetooth

Wanted to use the new Shimano e tube Bluetooth app to be able to check and tune my Di2 drivetrain. Had to replace my battery mount with the Bluetooth compatible version. PBK had the best price and availability, and with the discount offer, it was even better. I changed out the mount and a new Bluetooth d fly I already had, and the new system works as advertised. Sometimes it takes a while for the phone or iPad app to "see" the system through the d fly. Just started playing with the system, and I would like to begin experimenting with the road synchro and semisynchro shifting. With the hilly and mountainous terrain around here, it would be helpful.
