Mr Turner Shimano Dura Ace is the pinnacle of precision shifting and reliability. An excellent balance between weight and performance which is why I only ever consider Dura Ace
Austin Great price at Merlin makes this groupset almost justifiable. Oozes quality, from the lightweight materials and lovely paint finish. The brake and shifting action is incredibly light and precise and it is quieter than my ultegra di2 drivetrain.
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.
