Update your 12 speed road shifters!

Finally my 105 di2 shifter got a spare button! The update gave you the possibility to assign one button on your shifter for up AND downshifts for the front derailleur. This gives you one dedicated button to operate your cycling computer! Now I can tab for next page, but I double tap for previous page and hold the button for start / stop. That's such an awsome quality of live improvement. There are even more functions that can be assigned to the buttons but that's all I ever wanted from 105 di2
