Shimano Di2 Firmware Updates // Gear Usage Rate Now Works!

Solving the riddle of why “Gear Usage Rate” never worked on my Shimano R8170 12 Speed Di2 groupset this week with some online research and testing of the latest update released for the BT-DN300. With the 4.1.0 update Gear Usage Rate now works in the E-Tube app, but it’s not the only place you can track gear usage!
