Cool. Cassettes starting from 10t. Thats nearly a 10% increase in range.

10-11-12-13-14-15-16-17-19-22-25-28

Edit: Made a mistake of copying the 10s cassette jumps. Now updated with the 16t cog.

so if the 50/37 and cassettes starting at 10 teeth cog is the new "Pro" chainrings standard for 12s from now on. That means sub-kompact like 46/30 will be a new standard (sub-compact) for a general public like the 50/34 is now. What do you think?

WW should embrace 46/30 and 10-28/26/24 for the potential reduction in weight. I said potential, not actual so we shall wait and see.

The 16t is the 6th cog on a cassette that starts from 11. this one starts from 10, therefore the 15t is the 6th cog, which it does have. It doesn't have the next 1t jump to the 7th cog (17t on a conventional low range cassette) but it's already doing better than most modern mid to high range cassettes.

You could say it's got half of a 16t cog, and on the range equivalent of an 11-31 cassette that's pretty good these days!

I'm still not sure if it's a good idea for Sram to push a system that needs a new freehub, but it's growing on me.

With 46/30 chainrings and 10-28 cassette you will be on pretty much the same range as 50/34 and 11-32 but with much smaller jumps on the cassette. Also with 46t big ring you could be on 1 smaller cog for the same speed which would mean effectively reducing the "problem" of the missing 16T cog (with 10-28).

For me I would probably like 46/32 with the 10-28 cassette. Just 14 teeth difference between chainrings with similar range as 50-34 and 11-30.

The only thing that's bad for me is the forced change of Quarq power meter to the new one with direct mount rings. Need to sell it...

I made a mistake. It should have the 16t cog if cassette is no larger than 28t.

For 30+32t I don't think it'll have a 16t cog unless it's traditional freehub + 12s.

The chainrings are machined from a single block for further weight savings. 50/37 for the strong pros, 48/35 for most. Assuming there’s a 46/33 or similar for compact and gravel applications.

Not sure if direct-mount like CT claims. My bet is a really tight BCD and any loss in lateral stiffness is made up by the single-piece construction of the rings. Direct-mount would make things harder for Quarq to design around.

I think Wout has been on it a few weeks. Jeremy Powers is using it too, as seen here a few weeks ago in Gloucester.
