I would like to order some rotors for an enduro build and after a few searches on here i'm unsure of what to order.
I'm fairly new to mtb and rotor brakes so don't really have a point of reference to compare anything i might order from Ali.
Any suggestions? I know i want 203 or 220mm.
Anyone know of a company that sells thicker rotors? I have an mt5 calliper i'm using on this build and read they use slightly thicker than normal rotors.
Ztto seem to have mixed reviews.
Do i need floating? Do floating rotors fail at the joins?
Thanks.
-
I bought the ztto floating rotors in 160 and 140mm. They do seem thicker, even after alignment with spacers so that they fit centered between my brake pads. The 160 had a minor wobble which I corrected by gentle bending with my hand. I also had low speed brake shudder which went away after 10 miles of road riding.
Overall I wouldn't buy again simply because the solid steel rotors are plenty for me. But if I had to buy floating rotors, I would buy ztto again. Floating rotors do not have any history that I've read of failing. Also the ztto rotors are identical to differently branded rotors I see from Western bike retailers.
My experience with smaller rotors could easily differ from others experiences with the larger ones. More chance for a bad wobble to occur when bigger.

I think Onirii might have something right up your alley
They've contracted Stirling Design (designer of Niu Aero (http://cyclingcollege.com/index.php/2020/04/12/niuaero-road-01-review-1/)) to come up with these disc rotors that'll come in 140/160/180/203mm sizes with 6-bolt or CL mounting options. These rotors are supposed to be paired with the upcoming Onirii M4 and M2 post mount brakes for MTB. I guess this is also formal proof that Onirii are indeed working on proper mineral oil hydraulic brakes, hopefully we'll see a flat mount version of that 4 piston M4 calliper.

Interesting. Nice looking rotors.
Are those cable actuated hydro brakes? How are they?

The BR-05 callipers in the second picture are hydromechanical, I can't comment on performance because I've never tried them before but they seem to be the best hydromechanical option after the Juins which are 2-3x the price depending on model. The M4 and M2 appear to be proper mineral oil hydraulic and the M4 lever/calliper design itself looks to be very Trickstuff/Hope RX4+ PM inspired, but I'm not too knowledgeable on MTB brakes and could be totally off here.

I couldn't wait and ordered some random floating Rotors which it seems a few brands on Ali are putting a lable on. Hopefully they're not garbage.
https://www.aliexpress.com/item/4001191926306.html?spm=a2g0o.order_list.0.0.83231802HmbhyM
Was tempted by the version with cooling areas added but i have no idea if they're a gimmick or not.
https://www.aliexpress.com/item/32947453001.html
Can report back if anyone's interested but bear in mind i have minimal experience with disc brakes so it'll likely be limited to: They seem to work good or they don't work at all/fail catastrophically.
I wanted centrelock but didn't find many cheap rotors, so ordered some six bolt adapters from Sensah. Again another potential failure point, which is suboptimal.. fingers crossed i guess.

IIIPRO shouldn't be too bad. They co-develop the BR-05 hydromechanical and upcoming M4 hydraulic calipers together with Onirii and Onirii themselves used to bundle those floating rotors with their brakes before they came out with the CD-01.
and good eye spotting the cooling fin version! I wonder if they’re any thicker/beefier than the standard ones?

I've been using these lightweight Deckas rotors https://www.aliexpress.com/item/32964003633.html?spm=a2g0o.order_list.0.0.29ba1802DilydJ with 6 bolt hubs and when I switched wheels I got these adapters https://www.aliexpress.com/item/4000260123765.html?spm=a2g0o.order_list.0.0.29ba1802DilydJ and they have been working great in 6 bolt and Center Lock set up.

I notice that all the chinese rotors seem to have less material in the breaking surface when compared to Shimano/Sram. Wouldn't that affect performance/heat dissipation and perhaps mean they wear faster?
-
IF they are indeed thinner that means they will get to an unsafe thickness faster. Performance (however you wish to define that) and heat dissipation of a thinner rotor with all else being equal will likely be lower. Would you notice the difference? Probably not.
-

Heat dissipation is mainly affected by the heat sink area - the more the area, the better is heat dissipation. So highly perforated rotors have great heat dissipation. I've used KCNC Razors for years without any overheating problems (on descends with less than 500m of vertical drop), and now using Chinese rotors of the same weight (107g @ 180mm, 76g @ 160mm) with the same result.
But breaking performance is affected by amount of material on the braking surface, so there is a compromise, as anywhere else in the bicycle.
And of course, the less the material on braking surface, the faster the brake pads and rotor itself will wear out.

M4, M2, CD-02 (CL) and CD-03 (6-bolt) in 140mm or 160mm are now available on Taobao for pre-order
180mm and 203mm versions are also coming
There will be flat mount hydraulic callipers under the XR series

I thought so. I wonder how noticeable it'll be with the rotors i have ordered. What are you using now?
I see Kingstop make some rotors that look more conventional at a good price. May grab some of those if the IIIPros are not up to the task.

Not exactly these ones, but with the same shape as their "model 3"
Upd: https://aliexpress.ru/item/1005003246173815.html - these "19K type" are exactly the same as mine, but I've bought them a year ago much cheaper than they are now.
I will not recommend them for heavy and/or aggressive riders, but they'll be a good choice for average XC or DC bike.

Ah damn, i'm a heavy chap building an enduro hardtail. Those model 3's look to have a similar amount of material removed as the ones i have ordered. That said mine are 203mm so that may help. Guess i'll have to experiment.

So, I found myself in need of centerlock rotors (situation eliminates the possibility of using 6-bolt plays adapters)
Saw these on AliX under the Onirii store. Apparently they have stopped producing them altogether.
They can still be found under the Cactus brand, but I wonder what the story is behind why Onirii stopped making them…

I've flipped the cheap floating rotors i'd ordered after seeing reviews saying they start to rattle at the pins, as well as their low amount of material in the rotor itself + on the package they say not for Dh/Enduro use.. https://www.aliexpress.com/item/4001191926306.html?spm=a2g0o.order_list.0.0.21ef18028BRDsg
Picked these up instead, should have them next week. Reviews are good though i haven't seen anything specific to the harder side of mtb. They've got a more standard design and more material in the rotor with less cut out. https://www.aliexpress.com/item/1005004323711635.html?gatewayAdapt=4itemAdapt
The new Kactus look good. They're thickness is stated between 1.6 up to 2mm. Would be great if they're 2mm. Anyone tried them yet? Any rattles? How thick are they actually?

I can related to the issue with the pins becoming loose. I've been on these Deckas rotors for around a year now and they work ok, just a bit noisy with the rattle https://www.aliexpress.com/item/32964003633.html?spm=a2g0o.order_list.0.0.21ef1802TSybds

Good catch!
by the way, 'climbing' (https://tieba.baidu.com/p/7970315611?pid=145062090405) actually refers to 攀爬 (Trial)
I still wouldn't trust these rotors for road descending now that I know they can fail like this though...

I didn't end up using them as i decided i wanted thicker rotors. They did make a good impression, looked to be well made and i'd buy them again. Measured as described at around 1.9mm thick. If i was to order standard thickness rotors again they'd be my first choice at the moment.
I installed these instead https://www.aliexpress.com/item/1005004913085313.html?spm=a2g0o.order_list.order_list_main.15.136018027PawHV
Have had one short ride and i don't think they're bedded in yet. They're absolute chonkers. Quite heavy. Measured with two callipers at around 2.17-2.2 which i was slightly annoyed by so i found another set and they measured at 2.3....

Not very happy with these: https://www.aliexpress.us/item/3256804147936070.html
During 11/11 sale I bought 3 pairs that got delivered last week of November and one pair immediately went on my new build. About 300~ miles later I still did not have the "bite". Replaced them with my trusty old, used Shimano rotors and braking power is much better. Not sure if it is the problem with brake pads? I am using default pads that came with Onirii BR005. I did order semi-metallic pads later but yet to put them on since the performance with default pads + Shimano rotors is good enough for me. Anyone else with these rotors?

I also ordered these disc rotors but did not install them yet, they will be used for an older city bike...
If you use the original BR005 break pads, I would strongly recommend swapping them for alternatives, made a big difference on my bike using original Shimano disc rotors.

Semi metallic type or ceramic? I am not sure which ones come in the BR005 box.

They should be on the market soon as the 2nd generation CD-02 (CL, 103g) & CD-03 (6-bolt, 94g). 1.8mm thick and a stronger spider so hopefully they'll be more durable than the 1st gen.

ZRACE have a new rotor that copies SRAM centerline XR:
https://a.aliexpress.com/_mKUHwhY
-
Update on those ztto chonkers. They're working well (ok bar some noise issues with the rear but it's not the rotors fault i don't think). The front feels like it'll happily throw me over the bars in any situation if i want it to.
Only complaint is perhaps they don't need to have such a wide brake track and could save some weight here as you can see from the wear there's about 4mm that isn't used. But then again i'm not using them with the brakes they're intended for.
https://ibb.co/3z0k0fn
https://ibb.co/PcQ5BVn
Anyone have suggestions for any other 2mm or more six bolt rotors? May have to replace the rear and wouldn't mind finding something lighter as these are 255g each.
-
Interesting about the Zrace. Anyone have tried the rotor from that brand? They are new so there is no review yet.

Just ordered a pair of the new centerlock ONIRII rotors: https://www.aliexpress.us/item/3256804989446940.html (https://www.aliexpress.us/item/3256804989446940.html)
I imagine these are the replacement design that was released after the fiasco with the previous version (now sold by KACTUS and ROCKBROS) breaking apart under high load/heat. They seem to have more conventional and stronger 6-pin floating rotor design like SRAM and Shimano do. A bit thicker than the previous version too at 1.8mm.
I did have a little snag with ordering the correct version, they were listed as "centerlock" but the photo featured the 6-bolt design. I went ahead and ordered the centerlock option anyways. A couple weeks later I notice I had an unread message from the ONIRII store, they had messaged a photo of my order with the receipt...and in it was a pair of 6-bolt rotors instead of the centerlocks that I had ordered. I messaged them back and let them know that those were not the centerlocks I ordered. They replied right away with a link to a product page for a $1 shipping change, which I obliged to. Seems I will get to keep the 6-bolt set as far a I can tell for the moment.

The BR-05 callipers in the second picture are hydromechanical, I can't comment on performance because I've never tried them before but they seem to be the best hydromechanical option after the Juins which are 2-3x the price depending on model. The M4 and M2 appear to be proper mineral oil hydraulic and the M4 lever/calliper design itself looks to be very Trickstuff/Hope RX4+ PM inspired, but I'm not too knowledgeable on MTB brakes and could be totally off here.

Any chance you can cancel the order? Not sure why Kactus are still selling it but Onirii already recalled that model for spider failures (https://chinertown.com/index.php/topic,3627.msg39533.html#msg39533) and uneven pad wear.

Update on the new-design ONIRII 6-rivet floating rotors, which I ordered in 160mm & centerlock:
Last time I posted here I mentioned that when ONIRII sent me a message with a photo of my order, I spotted they had sent 6-screw rotors instead of centerlocks. I had messaged them back and they apologized for the mistake and directed me to purchase a 1-cent "shipping change" through them, which I went ahead and purchased.
A few days after ONIRII sent me a photo of my centerlock rotor shipment, and I've been waiting on those. From the photo, it looks like these are a bona-fide centerlock design and not a 6-bolt rotor with an adapter. They also demanded that I give them a good review for the good service, which I suppose I will give considering that their response to this mistake has been solid and it seems I am keeping the 6-screw rotors for free.
In general I quite like that ONIRII sends photos of the shipment and the shipment receipt (with your name and address on the receipt), which is helpful for ensuring that A) you are receiving the correct product and B) it's shipping to the correct address. It's a nice CS touch that I haven't seen from other vendors.
In the meantime, my notes on the 6-screw rotors, which I received last week:
The good:
-weight: 94g, basically on the money for quoted weight
-thickness is indeed just shy of 2mm. Can't get an exact measurement bc the battery on my caliper died, but I can see it's definitely thicker than 1.5mm.
-Nice clean machining and anodization on the spider. area of the 6-bolt interface is machined down to match the thickness of the rotor so the rotor aligns on the mounts correctly.
The bad:
-Rotor has a couple of burrs left over from cutting (laser cutting?)
-plenty of sharp edges. You probably want to file/grind the outer edge down for peloton use.
-and the big kicker...ONE OF THE ROTORS IS MISSING A RIVET. Huge mistake from them. Basically sent me a useless rotor. The fault was visible in the photo they sent me earlier, which is good. Thankfully the replacement rotors they are sending have all the rivets. Anyways given how they've served me as a customer, I have no doubt they'd make it right if you were sent a rotor with a missing rivet, and you'd have the opportunity to catch it before they even ship. But it's something to keep in mind if you're ordering floating rotors from any of these AE vendors.

I guess I'm primarily a bargain hunter, so at that pricepoint why not just get shimano or sram rotors? Are these ultra weightweenie rotors?

In terms of weight, they are pretty much the same as MT800 coming in at 101g w/o lockring, 112 with lockring.
I'm not sure what the price difference is for you--I know Europe gets lower prices on Shimano parts and higher VAT on Chinese imports compared to the US. I paid $55USD total for the ONIRII rotor pair, while the cheapest 160mm high-end Shimano rotors (like MT800 or CL800) that I can find are at least $50USD each. So for me it comes out to around half the price.
I saw that you might be paying something like 33 euro each, and there are MT800/CL800 rotors available in europe for around 40 euro or less, is that correct? If that's the case, then of course the ONIRII rotors make no sense.
-
This is true. Shimano stuff is comparatively expensive here. I frequently check Merlin Cycles even though I am in the US and they certainly have better prices on Shimano stuff but shipping across the pond kills any savings unless you order upwards of $500? I could never figure out how their shipping costs work. Right now they have great price on Ultegra R8000 full group and when added to cart shows free shipping to USA + no tax.
Wiggle has quite reasonable shipping to USA but they don't have much of the stuff. Either that or their low prices are applicable only to a particular slow selling variant of a product.

Definitely too expensive, at the price lever of those we can get ashima's or galfer's , as well as Shimano even if not so light but hey it's a Shimano

An update on ZRACE rotors that they were blowing off at $5 a pop during last 11/11. As of yesterday they are on 3rd bike and 4th set of pads but no dice. Here are the pads that I tried - OG Onirii, Cooma/Delt, TRP, Tektro. Currently they are on my Salsa with Tektro pads and same poor performance continues that started with my VB GF002 months ago. I almost gave up on Onirii BR005s thinking the calipers were shite but no! The rotors are shite.
I honestly didn't think the rotors were culprit and blamed it on pads and calipers. Just going to stick to Shimano (even used ones on Craigslist feel better) or if someone has better options on the cheap let me know!

Which ones and whats wrong?

Just no strong "bite" even when dry. Brand new but give a feel like they need to be replaced.

Update on the new-design ONIRII 6-rivet floating rotors, which I ordered in 160mm & centerlock:
Hey bro any updates on those new design rotors ? I am looking for some lightweight rotors and considering those as they're way cheaper then galfer

Uhh they're ok. I'm still riding them over a year later. Not so zooted about them but they're fine. I judge they don't have great traction at the pads, even when bedded in. I'm having better results with ceramic pads, but they definitely sacrifice some traction, discs with more surface area are much better. My biggest complaint is the rivets eventually start to go loose, which make them super noisy. I've been able to fix the issue by re-peening the rivets by smashing them on a vise anvil with a hammer, but there's only so many times you can do that before they go brittle and break catastrophically.
They're like 1/4 of the price of galfers right? Expect about half the quality & performance in terms of braking performance and durability. So maybe you're getting double to 50% more value out of them compared to Galfers, if you can tolerate the crappy performance.
I live in the Boston area if that gives you some frame of reference for the terrain I deal with. I get satisfactory performance going down big hills, criterium racing, and riding in groups. But I haven't really tested them much on real mountains.

Thanks a lot for a very comprehensive answer bro. I am currently riding dura Ace rotors but last week was in the mountains and they wobble under heavy load. Also after just 5k they show wear and almost at 1.6 ... But I think I will go with the galfers for a peace of mind before my trip to the Alps in September.

Yeah for a trip to the Alps I would say the ONIRIIs--or honestly any weight-weenie rotor--are definitely a no-go. I would check the thread on WW for discussion on what to get: https://weightweenies.starbike.com/forum/viewtopic.php?f=3&t=145230&start=705
seems that most users there are recommending a rotor from campy, shimano, or SRAM, and feedback on the galfer waves seems to be mixed.

I'll just order a new version dura Ace rotors and call it a day. They just look the best anyway .

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.
