Hi all,

I'm looking to build a fun bike for casual coffee runs and commuting when the weather is nice. I love the look of old TT or pursuit bikes that have bull horns and am looking to use bull horns and tt base bar dual control levers. If I use a ultegra Di2 6871 lever do I need the other lever or will it work on its own? Do I need to have the extension shifters too for the system to work or no?
