Hello!

I have bought some second hand SW-R671 two-button, old style bar end shifters. The brake levers are the new R8060 one button style, and the battery is a DN110.

For whatever reason, the buttons on the right bar end shifter (controlling the rear mech) are the “wrong way around”, ie that the bigger, lower button moves up the cassette. This is the other way around to my other di2 setups (ie rear cassette moves outboard, down the cassette, when the lower button is pressed).

I can’t work out how to fix this in the etube software, which seems to only let me fiddle with the brake lever shifters and other stuff about synchro shift.

 Any tips, please? I’m not very experienced at all with e-tube, so it could be that, but the setting is really not apparent. Equally I might have missed it amongst the options amongst synchro stuff, but I would rather not use synchro at all on the TT bike.

Thanks!
