James Not a lot to say that you haven’t read elsewhere about Di2. Faultless shifting. This kit is a useful upgrade if you’ve already got a decent setup. I’ve upgraded from mechanical Ultegra 8020. Which in itself was great, but I always said I’d try Di2. I needed to purchase another 400mm cable to fit the kit to the bike. I also bought the wireless unit and bar plug junction box for a clean installation on my Giant TCR.
