Chainrings "other than" OEM for Ultegra SL or Dura-Ace 7800?

YUMEYA FC-7800 DURA-ACE MACHINED 53T CHAINRING




Is it just me, or do they look "just like" Ultegra SL?



The Yumeya ring seems to be 95g (which is 10 less than a standard 7800 ring).
The standard Ultegra SL 53T ring is 114g (hard for me to locate a weight...only thing I saw was ".25 lb")?

I would also say it looks like an Ultegra SL ring;

Yumeya is OEM, they are Shimano's in house very high end parts 'Yumeya is Japanese for dream workshop, and Yumeya components deliver on these dreams being crafted with pride for beauty and performance resulting in the ultimate lightweight and efficient upgrades for your Dura-Ace groupset'

The difference is that 10g that you are paying for, and a nicer finish, there are also several visible difference between the Ultegra SL rings and the Yumeya

Thanks. I actually prefer the Ultegra SL ring's aesthetically, but wanted the smoother shifting of the Dura Ace ring
(the difference was noticeable, but not by much more except when under load...that's where the DA ring would shine).

The Yumis' teeth seem to be machined differently.
I would imagine it's to fine tune shifting maybe?
(better than 7800 or at least comparable?)

I think I'm going to go for them.

For $175., it's a big gulp and the 10g's won't be much of a savings,
but "if" it shifts at least as good as my Dura Ace 7800 ring
(which is great by the way) and I can bring balance & visual
harmony back to my bike, it would be worth it for me.
