Rotor Qarbon Q-rings - it is aluminium and carbon inserts.
Moderator: robbosmans
I happen to acquire the new Rotor Qarbon Q-rings for my bike and so far so good. I like them. They are 20g lighter than the older version. Not much. It works just like the older version. I cannot say one is stiffer than the other but my butt dyno.
50t @121g
Here it is installed.

Wait whut? When did they start making these? I Just had to buy a new 52T 130BCD. Didn't see anything of the sort out there for sale. IT just an insert obviously...looks like the Aero rings, just with carbon insert...pretty bad ass looking IMO!
Maybe they don't make 130BCD for these yet?

Thanks! Rotor just recently started making them available to the masses. I saw many on ebay but purchased mine through my LBS. Perhaps contact Kervin at Rotorbikeusa ?
Correct, it is basically milled-down aluminum then further reinforced with carbon. I think I like that better than carbon chainset.

^ROFL....anyway. Yeah, looks like 110 only now. I can tell my aero 130BCD is stiffer compared to the last regular QRing I had, imagine the carbon/design would help some...but I've never had issues with shifting and Di2 with either one anyway. But if it translates to 2w to the wheel and saves some weight, so be it!!

Really, so they can make a 52T QRing similar to the regular QRing shape, not he extreme? Seen a review of one of them, it looks more like OSymmetric/Froome/Wiggans with the most extreme osymmetric shape, which is a hassle for FD setup.
Regular Qrings require no different setup on the bike once mounted and set the height of the FD.
Thoughts?

the first time seen this style of qrings.
rotor is big company and they should tested them.
i think no problem.

Well, after 2 months of use, what can I say ?
-A little bit lighter, yes, 10 grams. I don't feel the difference
-A little bit stiffer, yes... but don't hope feeling much, I think it's lightly sensitive above 800W.
-What is not said is that it's less noisy than the original Qrings, and I like that.
-The finishing is good, I like what it looks. Usually when you add carbon to an aluminum structure, the whole piece is heavier, but in that case, it's lighter. Some people will like the design, some other ones will dislike...
-Adjustment was very easy and shifting is perfect (Sram red Yaw probably helps !)
The real revolution in performance would be to have more carbon on that chainring. However it's "just" 30% more expensive than Aluminum Qrings whereas usually on this market carbon is twice more expensive.
So, it's not a necessary product, but if you're fan of Qrings, you may consider this choice when your aluminum rings become used.
