Hi All,

As the title says, i'm wondering if i can use the R8070 shifter hood buttons with 6870 Kit. I cracked by best bike frame so have stripped off all the 6870 Di2 kit and want to use it on my winter bike...which is hydraulic so i need new levers. I fancy using the hood buttons to control my bike computer so was thinking of buying R8070 levers rather than the older non series Di2 hydro levers.

I already own the older d-fly (EW-WU101) unit and older battery (SM-BTR2). Should these work with the buttons on the R8070 levers (to control my whaoo pages) or do i need the new BT d-fly (EW-WU111) and new battery (BT-DN110)? If that is the case i won't bother, i'll just get the older levers off ebay (half the price!).

PS, im not that bothered about connecting to my phone, I have a PC for updates.

Thanks in advance

Thanks.

As i understand it then, i can use:
R8070 with EW-WU101 and SM-BTR2 to control the pages on my ELMENT

I cannot use:
R8070 with EW-WU111 and SM-BTR2 to connect to a smartphone as BT-DN110 battery is required


Could i use:
R8070 with EW-WU111 and SM-BTR2 to control the pages on my ELMENT? This requires ANT+ only so may work?
