Review: Great Di2 short cable - Perfect Di2 cable for short distances. Good to have as a spare
Review: Don't worry too much about the length - I'm new to Di2 and purchased this as part of adding the wireless unit. The recommendation is to buy the shortest cable available, but I couldn't find it anywhere. This worked just fine. At least on my bike, there is plenty of room to stash the little bit of extra cable that I ended up with. This is a nicely made cable, albeit a bit expensive for what you get. But that's the nature of specialty cables. Get over it and enjoy the ride!
