I've Just noticed that my "new " r1 received 2 days ago is like a new version
It has the same lockring on drive and NDS, and weight a Little more than previous received in june
I can confirm the same. I bought another crankset and received it a few days ago. The weight came out to 401g WITH spider which is around 40g heavier than my old one.
As you can see in the picture below, it's the same lockring on both sides.
I think I know the reason why they made this change. Now that they have a 24mm Ti spindle option, they want to have more parts commonality between the two sets. Look at the picture of the titanium spindle. I bet that you can swap spindles between the Ti version and alu version.
If so, it's good news for people who want the more subtle branding of the titanium version. Maybe you can buy the Ti version and ask them to buy an extra 29mm alu spindle.
Note that they still advertise the alu version as 40g lighter than the Ti version, but that is not true anymore. The difference will be less than 10g.
Also, it makes you wonder if the other carbon cranksets that seem to be the same (such as Rockbros) have also made the change. If not, I'd think about buying the Rockbros crankset to save 40g. Although I really hate the branding graphic on it...
