2022 - Rotor recommendations?

[Bigbobby1482]

Just adding in, I have the ONIRII CD-02 lightweight rotors in center lock 160m.
They were 101 grams without the lockring.
I really don't have much confidence in these rotors, they sound really odd under heavy breaking due to the massive holes in the pad contact surface. They do break fine, and pad wear doesn't seem to be affected, but it just doesn't sound right.
 I don't live anywhere hilly, but not gonna risk it. Have been riding them for about 500km

 I'm probably going to swap them for a shimano or galfer, something with more contact area.

I'm using the same rotors on one of my bikes and majority of my rides are climbs and descents. So far they've held up, though I weight under 70kg. I noticed the Panda Podium sponsored racing team is using them on their bikes as well.

Curious about how many miles/km you’ve got on them?

My biggest reservation with the loosening rivets is heat—I imagine that as the steel discs expand they push the rivet around. Of course all floating rotors do this, but my sense is that these rotors handle it poorly and permanently deform the rivet in the process. So I find it surprising that you are subjecting them to a lot of heat on these rides, and you still aren’t getting the same issue

I rotate my road bikes every other ride. Also I tend to either late brake on descents to minimize the time I need to brake, feather the braking on curves (like an ABS system on a car) and use my body to create wind resistance to slow down. Plus I try not to get that grinding noise when braking which reminds me my rotors are heating up. So I tend to switch back-n-forth from rear to front to modulate the braking force. My gravel bike tends to get more braking on the trail, but I'm not an XC downhill racer so I'll ride at a slower pace.

Has anyone used rotor zrace rt-rx plus ice-tech or meroca ultralight sr03 (looks similar)?
Could you share your opinion?

I use this Enlee rotor, which I believe is the same. On sale it can be US$13 or so. It's great - installs fine, solid, no more noisy than any other disc rotor, packed well (the second pair I ordered came in boxes). The only downside is that it's heavier than advertised, the 160mm rotor is about 140g, excluding the lock ring.

Oh, and the lock ring is the externally splined one. Great if your bike uses 15mm or bigger thru axles, but for 12mm thru axles I much prefer the lock rings with internal splines.

 MANA version is lighter and honestly those are best rotors I've used up to date l. Way better then dura ace/xtr

Arent these the same? They come as zrace to. Had them all and they seem rebranded.

They look same but for some reason MANA are lighter. I personally have them and they are best rotors I've used to date.
