1. Do you know if the brake TT levers ST-R8060-R will work with the bar end shifters SW-R671 please.

      Yes they will work together, but check the Shimano compatibility chart linked in the post above to verify.

      1. Thank you for taking the time to reply.

  2. Hi, I have St-R8050 Shifters, SM EW90-B Di2 Cockpit Junction Box 5-Port, Di2 SM-JC41 Internal Junction Box (4 ports), FD 8050 Front Derailleur, RD 6870 SS Rear Derailleur, Di2 External Battery Mount SM-BMR1-S, Di2 External Battery Mount SM-BMR1-S. and somehow the Shimano E-TUBE doesn’t recognize the battery. It is brand new battery and brand new Battery mount but system can’t recognize them, shows “Unit is not detected”. Any suggestion or recommendation? Thank you so much.

      First, make sure everything has the latest version of firmware. Second, try connecting to just the battery and not everything else, with just 1 wire between the Junction A and the battery.
