Next generation of Dura-Ace Di2

[cyclespeed]

Given that there is still not even a sniff of what the new DA Di2 will look like, surely the official release will not be until well into 2021, and potentially able to buy a set Summer 2021, assuming they can make enough stock...
Everything is delayed at the moment, and COVID is a great catch all excuse, sometimes justified, sometimes just a cover for poor management, but basically, NOTHING is gonna be released or sold early at the moment.

Covid is a major impact. You have huge consequences of it. Huge. Lockdowns, entires teams sent home. People at home (not working) due to school closures. The impact is huge! It will naturally delay everything.

Covid is not an excuse, its reality

I read on Wielerflits that Jumbo Visma will have access to their Cervelos with the new Dura Ace groupset from January. And that this group set will not yet be available to consumers. Then at least some more spy shots will pass. Launch probably on their anniversary in March?

Yes I’ve read that too. Unfortunately on the picture and video it is definitely not clear to see that there is a new gruppo used..

on a YouTube channel in Spanish.....they speak (speculate) about the new

that surely something will start to be seen in the 2021 Tour or a little before
the information embargo will be lifted in July
first bikes with mounts in September, and little by little components will arrive at the stores.......The latter is logical due to the manufacturer's programming........2021 is already covered or almost

So after checking that new info and dates I guess the bikes that will be launch in 2021 will not have the new di2 yet, 2022 gonna be the proper time to get a new bike and the new di2.

So you mean it’s true? I can spot the new Dura Ace on Jumbo Visma Cervelo training bikes here in the Netherlands?

only Van Aert is seen with a Cervelo S5, bike brand your team will use in 2021.....nothing more than that ... it is supposed to be assembled with material from this year's team

I’ve never said that..

Since the new Dura Ace is gonna be a long wait I've decided to tinker a bit and create my own custom cassette, one that mimics the rumored 11-34 cassette. I currently use a 11-32 but could use an extra gear especially in the winter when I'm often battered by the cold winds on steep grades. The Shimano 11-34 is crap for road riding as it has wide gaps (11-13-15-17) on the high end. Nobody makes a 11-34 with road ratios and good shifting that I'm aware of. The closest cassette to a 11-34 is the Sram 11-36 but it's not ideal with a 13-15 jump. So yesterday I decided to see if I could make a 12-34 out of several Shimano cassettes I have lying around. So I've created my own 12-13-14-15-17-19-21-24-27-30-34 which is the same as the rumored 11-34 cassette sans the 11T. I could live without the 11T in the winter but I look forward to the new 11-34 when it becomes available. One good thing about the 12-34 is that I'm able to stay in the big ring longer than I could with the 11-32. And when I climb in the small ring at around 10-12mph the chainline is perfect, with the chain riding in the middle of the cassette. The 15-17 gap is smaller than the 14-16 gap I have currently on the 11-32. I gave the 12-34 a good test today riding in the strong winds and with 3,000' of elevation gain. I have to say it's much better than the 11-32 albeit it's missing the 11T. So in summary I really look forward to the 11-34 as it's a big upgrade to what I have currently. I hope the gear rumors are true and that the 11-34 will be offered in the Dura Ace version at a lighter weight.

For those interested in how I created the 12-34 here are the details. I have a 12T cog for the Dura Ace cassettes that start with the 12T. Then I took the 13-15-17-19 from the 11-34. I could take the 17-19 from an XTR 11-40 to save weight but the one I have is worn out. Then you need a 14T which I took it from my 11-32. Then I took the 21-24 from the XTR 11-40 and the 27-30-34 from the 11-34. Overall weight of the 12-34 is 301g., compared to 278g. on the 11-32. I bought a 14T for a Dura Ace to save a few grams. If money is no object I can save more weight by using a 15T from the Dura Ace and 17-19 from the XTR. Shifting is perfect. I increased the B-screw by one turn on the R8050 GS RD.

Very intriguing. Thank you for the detailed post!

Are you saying there is no degradation is shifting quality and speed, even when you shift from a cog in one block to a cog in a different block that you cobbled together?
