Great, more model numbers that probably don't make sense.
For example, I know 8070 is Ultegra Di2 disc, 11 speed. 8170 is the 12 speed version. 9000 series are Dura-Ace and 7000s are 105.
But I only know that by memorizing the numbers - there's no pattern I can discern, beyond the first digit. For example, why should a 1 in the second digit denote 12 speed? I don't see the logic.
Now I see we have a bunch of things labeled Cues (whatever that means) that will be different setups. It would have been a good chance to come up with a sane numbering scheme, but it looks like they didn't do that, based on the article.
