Saw that these are now on Aliexpress.
https://www.aliexpress.com/item/1005004315008249.html
and
https://www.aliexpress.com/item/1005004314866410.html
saw a few on here were interested.
they do look very nice, and reasonably priced too.
-
It is exciting to see some Chinese brands how they try to be as good as the Shimano, SRAM, Hope, etc.
These took good ideas from many models all in one.
Still 128g heavier than my Piccola's but Wow!
-
Saw these branded zrace too, look lovely tbh, might buy a pair just to see
-
Just pressed buy on a set of the Zrace ones as they're about £20 cheaper than the Onirii branded.
will update when they arrive!

Keen to hear how they are.

Trying to figure out if they'll send them to me left rear right front before buying a set, do these use mineral or dot?

Just ask them, Aliexpress sellers are generally quite responsive

They use mineral. zrace branded versions can be bought as parts if you have the ability to recable. They also come in silver which looks pretty cool, shame they only come with the red circles on the caliper.

Really hope these calipers' fluid displacement/piston ratio (https://weightweenies.starbike.com/forum/viewtopic.php?f=3&t=166497&start=15#p1745538) is similar to Shimano and Magura so they can work with Shimano and Campagnolo (https://www.velonews.com/gear/technical-faq-shimano-magura-campagnolo-shimano-and-other-mash-ups/) levers.

Zrace said it's 425g.
I think they looked the same.
Zrace M1

Not sure I would swap Campagnolo levers to another calliper.
They are too good to be changed ;)
Never fading nor rubbing.
The pads stick to the pistons that are magnetic.
-
They look like an updated version of the iiipro brakes.
https://de.aliexpress.com/item/1005002560141330.html
IIRC the guys who had them in the german forums said that the old levers were for quite big hands, and I think one had the issue that a caliper was sweating a bit oil.
-
I ordered a pair. Will send pictures and feedback once they arrive.
-
These look baller af and for a good price. I might get a pair if people have good results with them. Do they use Shimano bleed cups?
-
dunno about bleed cups and i doubt you'll get much sense from Onirii.. i've been trying to find out from what the equivalent pad they use would be but they can't or wont tell me beyond that they use their own E4 pads... anyone one recognise the shape?

Could be Hope M4/E4, Shimano m755 pads?
-
Would really kill my interest in these if the pads where proprietary tbh
-
The pads look similar to Shimano 4 pots - except for the horns on the outer part.
-
5 pots?
-
the 4 pot pads look very similar to Hope E4 pads, see: https://www.chainreactioncycles.com/nukeproof-hope-tech-3-e4-mtb-disc-brake-pads/rp-prod175496
-
Certainly looks like it. Need some sort of confirmation though.

5 pots?
Oops - dang near created a new category
-
These look identical to the hope v4 pads, right down to the pad retention screw.
-
They arrived today, and my, they are pretty.
ordered on the 2nd June, so 22 days to the door (UK)
They came in a air pocket pack, no box, but all fine and no damage.
front came fully bled and set up, rear came with the caliper attached to the hose, and the lever separate, plus a bag of gubbins.
they'll go on my tame trails bike, less chance of me killing myself if they fail.
I'll update when I've got them fitted.
-
Silver looks great. If i buy some i'd want silver 4 pot versions. Which of course are not available :/
-
Finally got round to fitting them a few days ago, after a bout of illness has stopped me going out.
So not used in anger yet, but I thought I'd give a few details on how it's gone.
Firstly, they come set up front left hand. which, being British is all wrong for me. First thing to do was swap the levers.
This was as easy as it is with any brake. 8mm spanner at the lever, undo, pull out hose, swap round and luckily no need for a new olive.
The hose is fairly flexible, but doesn't seem to need, nor come with, a barbed end reinforcing thingamy.
Now, I said the separate lever and caliper and hose didn't come filled. that was wrong. the lever has a screw in cap in the end with 10mm spanner flats. the hose has a small screw with a rubber seal to seal the end. fitting is a doddle. cut to length, remove caps and screw, fit lever rubber cap, screw thread compression bit and olive. pop it all together and nip it up.
in theory you shouldn't need to bleed it. however I will. I say will, as the bleed nipples are not a size I've got. the caliper end is M3 (I think), the lever end is M5. I have a multi size kit coming, so I'll update on ease of bleed and exact sizes.
Fitting the calipers to the bike is easy, as you'd expect. The levers are easy enough, it's a similar type setup as avid/sram used, a wrap around clamp with a bolt that runs through the lever but it's worth noting that the edges of the clamp are quite sharp, so watch those carbon bars and make sure the bolt is undone more than needed when adjusting the angle of the lever.
The lever fixing bolt is a torx, couldn't say exactly which size, a T20 sort of fits, but is slack. T25 doesn't fit. it's like a t23, if that was even a size. fairly typical for chinese bolts to be a more vague size than expected. it is steel though, and you do need to give it a bit more effort to close the clamp. I'm going to look for replacements fairly quickly.
Back to the calipers, the pads on the X2 are shimano G04/G03 size. The stock pads look cheaper than anything I've seen before. I swapped them out with a set of used pads from my SLX/XT brakes to give them a try.
Aligning the calipers is easy, but for my bike needed a little fine tuning as they run close to the rotor.
first 'up and down the road' brake test was a little underwhelming. modulation was good, but ultimate power seemed to taper off a little. Now, I'm 90kg (give or take a few portions of cheesecake) and run a 180 rotor up front and 160 at the back, so figured maybe that was it. Then they started to squeal...and squeal.
so, back to the workshop to remove the glazing from the pads and clean them up.
decided to go with new pads instead of the well used ones, just to give the brakes a fair trial.
bought new resin pads, didn't want to risk the additional heat build up from sintered, even though they are my preferred in shimano brakes. Cleaned up the rotors with brake cleaner, cleaned up the caliper pistons, just to make sure there was no oil in there too, a light sanding of the new pads prior to fitting and out I go for a couple of road hill reps to bed the pads in.
immediately different from the near outset.
Modulation is on par with my shimano's, albeit the final bite comes a little longer in, but ultimate power had me endoing down the hill, even with my butt hanging off the back of the saddle. All pretty controllable too, had a couple of nice nose rollers balanced, to my surprise.
The lever feels firm to use, little flex in the lever and only a bit in the lever body on the bar. It has enough shape not to be too narrow and not to wide. it reminds me of the feel of my old Hope Mono Mini's, but with more bite.
ultimate proof will be in the longer riding though, but so far, I'm hopeful (no pun intended)
:-)
-
Thanks for the write up. So they have almost no modulation like Shimanos?
Keen to hear your longer term impressions when you have formed them.
-
Some people on the german forums also have them on their bikes now. And found a way to bleed them (3rd link)

First impressions are good!
-
Thanks for the write up. So they have almost no modulation like Shimanos?
was out for a short ride last night with them. they have more modulation than shimano's. My Xt 2 pot's just seem to bite, with a little give, but it's quite a short window.
These, rather unsurprisingly, feel more linear. there's a fair bit of travel to get to the bite point, however I think that's more to do with the really strong pad springs I have, pushing the pistons back, rather than just keeping the pads in place. once at the bite, there's maybe 1.5x the lever travel once you hit the bite point to getting full power.
That took a bit of getting used to. I like the shimano's for their warp speed into anything and brake late, but you need to be quite subtle with feathering etc. these, no problem, grab a bit of brake and squeeze more for more power.
I'll try a few tricks to get the bite point a bit closer and see how they go.
one thing I did realise though, is that on my local trails, I brake a lot less than I thought. :-/

Another "test" from someone with some engineering knowledge

^ Doesn't sound good..
-
That's a decent breakdown of them. there are quite a few sharp edges, some need a bit of buffing, mainly those that are in contact with the bars, to prevent point pressure.
The calipers have a rough finish on the inside around the pistons. Although I never thought it would be that much of a problem. they're cheap brakes, it's a hidden area.
he reported caliper flex is a bit worrying, can't say I'd noticed it in use, but....I'd not really looked. I'll need to keep an eye on that, if it looks like it's flexing more than it should I'll def need to watch out for cracking.
The comment about the lever piston diameter is interesting, admittedly it's not something I'd considered as most manufacturers for their mainstream brakes, I thought got piston seals in x size, so make the pistons to suit! there are notable exceptions, I guess.
It's not that they lack power, they don't deliver it in the same way as a servo wave brake. Over the next few rides I'm going to try a few different things, one of which will be swap out shimano levers onto the caliper, and shimano caliper onto the z race levers and see if each end behaves differently to stock. plus look at what impact fitting better hose has. the stock hose is really flexible.
-
Any additional updates? I have a set of 4 pots on the way to try out. Installing a banjo bolt and bleed nipple are on the list of things to test.
-
I'm keen for any longer term updates on these as well.
-
mine still work, haven;t leaked and haven't changed in performance.
still not got around to changing hoses etc, but they're doing fine, even through my mildly neglectful attitude toward my ride anything bike.
-
Any new updates? It seems that Zrace now has changed the red caliper bolt to grey for more minimalistic look. IIIpro E2 and E4 also seem to offer the same brake but in different colors. Yet I see some differences between photo's (even on same product page). Some levers have drilled holes, others don't. Some have a turning knob for lever travel, others just have a bolt. Seems like a bit of a gamble on which version you will receive. However these are just minimal points. would like to know some real life experience on these brakes. Would be intrested in buying a set for my gravelish XC bike. Could help to get weight down to around 7kg without breaking the bank

Did you get to swapping them around with the shimano stuff? How are they holding up?

So I received my IIIPRO E4, which are exactly the same as upgraded version of Onirii M4 (also available on Ali now). These brakes have perforated levers and tool-free reach adjust. I ordered them in purple color (and to be honest it was the main reason of buying them). Weight difference with my old 2-pot Formula RX is less then 10 grams for the whole set (and Formulas are heavier though). I haven't noticed any caliper flex, that was reported by German guy for M2 model. So far I've installed only front brake and made one short ride on mostly flat terrain. Conditions were not the best for brake testing (a lot of muddy roots and fallen leaves), but front brake seems to have enough power (stoppie without problems), at least with 180mm rotor. I also like short travel of lever (in this aspect it feels a lot like old Formulas produced before 2013) and its square-ish profile.
-
hi all I'm also looking for a backup brake set, do you have any suggestion about choosing Onirii, IIIPRO, or ZRACE? or any other?
they look all the same for me but for example I would prefer buying from an established/well known seller on Ali.
thx

They are not only look the same, they are the same (with different branding, which is common for Chinese stuff). The only difference between them is that there are "first version" (Onirii, Zrace) and "upgraded version" (IIIPro and Onirii again), and both versions are available now. Difference is in drilled levers, reach adjust knobs and brake pads. Zrace also seems to offer both pad styles.

Thanks zombie, however on the 2 pistons i can't see difference on the levers, is it the new lever on 4 pistons only ?
Thx

Yep, it seems that new lever and reach adjust knob are only for 4-piston model (at least till now). And all 2-pot brakes with different branding are all the same.

For this price range I can find a set of magura's mt4 estop, i don't believe it's worth the effort to try these onirii's honestly. What is it actually this caliper flex phenomenon?
-

Go with magura for sure if you are able to get a set for sub-$100. About caliper flex see last post on page 2 of this thread. And it seems to be an issue only for 2-pot version.

The IIIPro E4 hyd. brake set I ordered Nov 2rd arrived yesterday. I temporarily installed the front brake on my latest build. (It will be several months before this bike hits the road)
From my perspective, the caliper's body and hydraulic handle body are very good CNC'd single-piece units. They appear to be of good quality.
Due to the post about the "caliper flex" I measured the gap between sides of the cylinder then applied as much force as I could on the brake lever, and with the pressure applied, took a second measurement. No deflection measured. (Unless the Calipers can become really hot and then expand/deflect, I didn't see any flexing on the brake cylinder body.
Edit: I had a problem where no matter how I tried, I could not get the brake lever/clamp to fit onto my 22.22mm OD Carbon bars. I ended up having to slightly slot the hole that mounts the clamp by .003in outwards. Then all fit well.

I also don't understand why you would bother with these Chinese brakes if you can get Shimano / SRAM / Magura.... For the same price or a little more...
I am from the EU, so a set of these 4 piston brakes would cost me about 120-130 EUR. But I am gonna go with the newest deore 4-piston set from shimano for 175 EUR.

A lot of reasons though. Not all live in EU and can get Magura for a good price. Not all like Sram brakes (especially Levels, Codes are good but much more expensive). And to be honest, comparing these Chinese 4-pot brakes with Deore is not apples to apples comparison - even XTR Trail weights more. IMHO this time Chinese guys made really interesting brakes by copying Trickstuff levers and Hope calipers.
And all this without taking into account such reasons as trying something new or color-matching parts on the bike ;)
-
It's a backup set, my official cura brake needs a service. Moreover i like the aesthetic of these M2 so much :D
But have we understood if bleeding is easy or messy? Which tools are required?
-
Thank you for the feedback, I'll try them for a next build.
-

The lever bleed port is threaded like Magura. The caliper bleed port is threaded like the Shimano funnel.from here: https://www.mtbr.com/threads/zrace-m1-x2-x4.1205320/post-15673159

i've put an order for the ONIRII's M2, i like more the blue IIIPRO's but the discount on the onirii's was stronger.
wish me good luck! ;D ;D
-
Just bought the 4 pots IIIpro's in blue. Discount was better than the oniri for some reason. will update once I have them. I will test them out on my "extra" rigid hardtail. If they perform well, I would move them to my XC bike. But all to be seen. Will update my findings. hopefully they stop better than my sram levels which are quitte underwhelming
-
Does anyone know what alternative brake pads will fit the 4 pot version? My guess is that the brake will be delivered with something that will work but can be improved. So I would like to get a headstart and order some "mainstream" brake pads to swap in when the brake arrives. THX for the info!

Hope E4
/V4
Upd: E4 only
-
for the 2-POT version we said Shimano pads G04/05 should be ok right?
any other model?
-
Hope E4/V4
I just asked ONIRII on Aliexpress yesterday and got this response:
What brake pads are compatible?
=> "same as hope"
=> "E4 M4 resin pads"
Then a more mysterious
=> "Shimano Hope" ???
-
As the 4-pot caliper seems to be cloned from Hope E4, highly likely its pads should fit too. At least pads' dimensions are pretty close. I've ordered pads for Hope E4 and will confirm if they fit or not when I'll receive them.
Then a more mysterious
=> "Shimano Hope" ???
I think this was about 2-pot version with caliper design "inspired" by Hope X2. If I right understand what they were meaning - Hope X2/V2 pads and Shimano 9100/8100 pads have nearly the same dimentions (0.6mm difference by length), so both will fit. But this needs practical confirmation.
-
...I've ordered pads for Hope E4 and will confirm if they fit or not when I'll receive them

From Aliexpress ?
Yes. This seller (https://alphabicycling.aliexpress.com/store/1100985550) have big variety of pads for almost all brakes - semi-metallic, ceramic and sintered.
-
Some photos of brake pads for 4-pot version.
1st photo - stock IIIPro on the left, pads for Hope E4 on the right
2nd photo - pads for Hope E4 installed into the caliper
I also want to warn that Hope V4 pads would not fit
-
Some feedback after using the brakes for a while. Did around 400km with them now and I'm very pleased. Packaging was very good. Some things to look out for: bolt that keeps your pads in place is strange dimension of torx. Combined with loctite or paint, the bolt was very tight when delivered, that made that I almost completely stripped 1 bolt when trying to swap my pads. Ordered some gold titanium bolts to replace anyway, so not that big of an issue. Same thing applies for the bolt that clamps down the brake on the handlebars. The clamp to hold the brake lever can be installed without removing your grips but it is a narrow fit. Installing is pretty straight forward. Lines are filled. Rear brake is not assembled but has plug in it so easy to install. I needed an extra hand to mount the clamp and the lever. You need to hold the leverhousing in place, hold and push together the clamp and then put the bolt through. So for that step I needed 5min assistance. On the rear the caliper is completely outward and touching my frame. The disc rubs just a bit in the beginning. This means that 1 side doens't move all that much. But I guess this is frame specific (Bergamont revox team) because I had the same thing with the sram brakes.
Now over to my findings of performance: They are way better than my sram Level TLM/ULT. Didn't swap my lightweight rotors to compare and it's a world of difference. The lever travel is easy to set so my short fingers can reach the levers. They are very snappy when releasing. They have a lot of stopping always. Did rides in dry and very wet/muddy situations and they never failed or gave the impression that they lacked power. I'm very happy with these brakes because they didn't break the bank, shaved 100gr of my bike and have infinite more bite and power than my sram brakes. Will keep riding them to get a more long term view but for now it seems that I will get another set to put on my XC bike.

Have any one shortened or changed hoses on the m2s?
What spares will fit (olive and insert)? Does it use shimano style ones?

I have no hard evidence but I bet they will be Shimano bh90 standard.

I have the Zrace branded versions and yes they use the Shimano style olive and barb.
-

They use BH59. Both the olive and barb are brass colored.

Only the internal diameter is different. They use the same olive. Different barb. Use bh90 for a supposed slight performance increase.

Hi all, just wanted to share my experience (again) on these brakes. Still on my rigid hardtail/gravel bike and loving them. Absolutely no loss of power or any other signs of fatigue after using them for quite some time now.
Last week I installed them on my XC bike aswell as on my fathers. Already the 3rd set of sram level TLM's we're trowing of the bikes to replace by these chinese brakes. The difference is huge. I now can actually stop when I want ;D
On my rigid bike (size S) the rear brake caliper touched very slightly on my rear triangle frame. I don't have this on my XC bike (same frame but size M). So I guess that normal build people will have no issue installing them.
Will keep you guys updated if anything should break or happen. No news is good news 8)

These Clarks brakes look identical to the M4 brakes.

The name was changed to Lewis and l must say they look rad from promos in Insta. Clones of Trickstuff and hopefully they'll have their power too. The silver looks fantastic
