Just be sure to add about 50mm of length for a crash loop near both the shifters. If you crash and the shifters move, that movement can disconnect the Di2 cable if you don't have enough slack in the cable.
Great thanks. I measured my bars with the string technique and they are 43 1/2 inches or 110.5cm. Now in terms of the EW JC130 cable, which length would work best? They have odd lengths like (550/550/50) (450,350,50) & (250,350,50)? A bit confusing.
