Electronic & Hydraulic Shifting (Di2, Ui2, customisations)

My point is that the non eletronic parts all have big added $ value with DA whereas the difference in those parts between 105 and Ultegra is only a few quid. By the time you're spending di2 money, who cares about saving £25 on a £250 mech. The price gaps need to be bigger for it to be worth it
