Did you read that article? It says that it will make only 105 as their top of the line mechanical components. Mechanical Ultegra will seize to exist after 2022 maybe 2023. Which means that if 105 will be the top of the line mechanical groupset it will no longer take advantage of trickle down technology from DA and Ultegra. And I have a sneaky thought that eventually 105 mechanical will go electric and they'll stop 105 mechanical as well leaving us with Tiagra.
We need to be very vocal to Shamano about their plans to eliminate mechanical DA and Ultegra, if they get enough E-mails telling them to keep the mechanical DA and Ultegra stuff they could change their minds. But as far as I'm concern I see this as a move by Shamano to try make more money by forcing us to buy batteries every 3 years at $150 dollars a pop, instead of making no money on a sale of a DA or Ultegra component package over the life of the components. And the long term life expectancy of Di2 system as a whole is only 8 to 10 years, so now you have an absolutely serviceable frame but will need to replace the entire Di2 system at HUGE cost. Like I said before this all about churning money out of our pockets into theirs constantly just as appliance companies have been doing for years (just one example), so shareholders can make money.
The only thing that story does mention is that Shamano could release a new line of mechanical derailleurs, but that only comes from the editor, it does not come from Shamano. Shamano is cagey about future release stuff, so time will tell what they'll do, but I seriously believe that if we do not take a stand and bomb them with emails requesting that they keep DA and Ultegra as mechanical they will indeed seize manufacturing of mechanical DA and Ultegra because they'll see it as there isn't enough interest from buyers to keep the mechanical stuff. So I believe it's up to us to make some noise as to what Shamano will do.
