Bit of help and advice please.
I have put together my bike and fitted it with Ultegra 6870 Di2 (TT version with shifters on the brakes too) everything seemed to be going well, including the RD.
HOWEVER I am having trouble getting the FD right. I have got the low and high adjustments sorted fine with the 2mm Allen key, the problem lies with the electric adjustment when in the big chainring and biggest sprocket... the chain guide isn't far enough in to keep the chain on the big chain ring (due to the automatic FD adjustment) and it keeps dropping into the small chainring. I have switched the red button on to try and do as per instructions ie adjust the FD in micro amounts with the switches that usually move the FD.
Problem is that the FD doesn't seem to be electronically micro-adjusting with the red light on.
Any idea what I may be doing wrong?
Many thanks
