The thing I love about binge shipping on AliX is that feeling of Christmas every day as packages show up at the door.
These are the flat mount dual piston, cable-actuated hydraulic calipers from Juin Tech.
As far as I know, these are rebranded and sold as Yokozuna Ultimas (Ultimo?) as well.
Comes with two sets of what appears to be organic brake pads.
Not strictly a Chiner part, as they are not from Mainland China.
332 for both calipers, pads, and hardware. Maybe a bit less, as the cardboard spacers were still in the calipers.
Cost: about $222USD.

Hey 1Sigma,
Do you have a ride report on these? I'm debating between these and Juin Tech F1 brakes for a VB-R-168 I'm waiting on so you input would be appreciated :)

Hi Olie,
The frame arrives tomorrow, so hopefully a report soon.
Would try them on my current bike, but it's rim brake.

Seems a little on the high side for cable actuated hydraulic brakes? Maybe they have gotten a lot better but I had a set years ago that left me disappointed.
Especially considering I just got a full set of Deore M6120 4 piston brakes for $220.
Not trying to talk down on these, but point out a well proven alternative...

Yea, I hear ya
I think the difference is, for us roadies, we need to consider the cost of getting replacing shifters as well when we go full hydraulic. Whereas shifters are a separate piece of gear from brakes in an MTB setup

I wasn't thinking about road bikes. Disc brakes on road bikes were just starting to gain traction when I last had one so I won't ponder things I'm not familiar with. But I assume they have come quite a ways since my set of (mtb) cable pull calipers.
Thanks for clarifying your use and why you opted for them.

Like most great "innovations" for road bikes these days, MTB did it first lol
Disc brakes are quickly becoming the norm on newer road bikes.
You are correct, they have come away from a mechanical cable pull calipers and quite a ways from the first gen cable actuated hydraulic calipers.
These ones are particularly decent, capable of stopping fully loaded eBikes.
BUT - given the choice, full hydro is almost always the way to go

Hey 1Sigma,

So, I’ve put about 70km or so on these. And I’m pretty satisfied.
I don’t really notice the difference so far compared to the 3-piston Shimano MT-BR520 brakes I had.
As others have mentioned, modulation isn’t as good as full hydro but still good. It’s not on/off as some people make hybrid brakes out to be.
UPDATE: I guess the pads just took an ungodly amount of time to actually bed properly.
The braking power on these have significantly improved. I don't know what is considered good, as I otherwise use fully contaminated v-brakes on my other bike, but I can go from 40kph to 0 in roughly a car length.
At higher speeds (40kph+) they stop faster than rim, and about the same at lower speeds (<30kph). Haven’t ridden in the rain with them, but I’m sure they’ll be infinitely better than rim in the wet.
Honestly, I don’t know why I was hoping for. They don’t blow me away, but I guess with brakes boring predictability is a good thing.

Are they any better than the Zrace ?

Are they any better than the Zrace ?
Hey there,
I couldn't say, as I haven't tried the ZRACE.
Here is a review of the ZRACE and Juin F1s.
The GTs are better than the F1s.
If I had to do it over again, I'd go for the F1s, as the GTs just feel like overkill for typical road cycling (no prolonged descents). Confidence inspiring in rush hour traffic though

Has anyone tried the ZOOM HB105 flat mount or HB100 post mount brake yet? Seems to be a bit better than the generic ZRACE/ZTTO/other branded offering but of course is probably worse than the JUIN 2 piston. Interestingly enough, the general mechanism does seem to be rather inspired by the JUIN 2 piston including the +20mm bolt hole spacing that allows for a flush mount rear calliper in 160mm applications. Pad is the standard Shimano type like the Juin too.

Hey everyone, I just discovered a new brand called Onirii.
They are like most other brands in that they sell some rebranded bits (Onirii Attack crankset is what appears to be a rebranded Fovno Thunder Pro) but what is most interesting is that they seem to have their own brake design.
While their BR-02 brake is in its 4th design iteration according to their marketing and appears to be a rebranded ZTTO unit, their new BR-05 brake appears to be a completely new design that no one else on the market carries.
EDIT: I think I’ve solved the mystery. ZTTO brakes are outdated rebrands of Onirii designs. ZTTO’s disc brake (the one without exposed pistons) is the 3th design iteration of the Onirii BR-02 while the ZTTO rim brake is a rebrand of the Onirii BC-01 which has since been succeeded by the BC-02. Also, ZRACE has started selling the Onirii BC-02 and BR-05 as the R700 and BR-005 respectively.
EDIT 2: The Attack crankset is based on the Thunder and not the Thunder Pro as it has a 24mm spindle as opposed to 29mm DUB.

Not sure I understand, it is better to look at Onirii then?

There are multiple design iterations, at least with Onirii you’d be sure that you’re getting the latest one because they detail the differences in their product listings on Taobao. That being said, I’ve never bought or used anything from them so take what I write with a grain of salt. I don’t know if they actually perform well or not.
Regarding the versions with exposed pistons, it seems like that was actually the 2nd generation design done by a company called IIIPRO who produced them until Onirii took over the project.

I'm impressed. How do you find that much details about it ?

As I was working my way through Taobao listings and Bilibili videos, I noticed that Onirii only really came up in the 3rd and 4th generation designs. Mentions of IIIPRO tended to come up in earlier searches so I'm assuming that they're no longer in the picture or are simply less involved as far as current production goes. I would also say that you really have to use Taobao and Bilibili to find the newest and best components from China. For example the new VFV Deep-V seatpost and the super high end EXS bits can only be found for sale on Taobao. Only outdated lower end stuff tends to end up being advertised to international buyers on Aliexpress, Shopee, Lazada, etc.
EDIT: Okay so I got the story wrong. With exposed pistons: developed by IIIPRO. Without exposed pistons: developed by Onirii. Latest 5th generation: joint development between IIIPRO and Onirii.

Just found the Onirii BR-05 calipers listed on Ali… certainly worth a try for the next project.
The design looks well thought through which should work well with todays internal routed cables.

Sigh. True, but it stretches my already poor Chinese to its limit.
Die Taobao have a good English based app now? (I suppose I could Google that…)

I ordered these
https://a.aliexpress.com/_mMWwGLQ
I don't know if these are the 05 model you guys were talking about. I just see how the piston and cable mount position should be on the inside. This should allow less bending and binding of the cable with the housing leaving the rear chain stay and front fork.
I have the ztto which I assume are the bc02 brakes and the rear cable has binding from the sharp angles it goes to the cable mount on the brake. This causes the pads no to fully release.

They are! By the way, Onirii just released their CD-01 CL rotors (https://www.aliexpress.com/item/1005004016958694.html). On their Taobao store, they were offering free upgrades to it from the old IIIPRO branded 6 bolt rotors. Maybe you can try messaging your Ali seller to see if you could get the free upgrade as well?

Man…I gotta pick up my Mandarin lessons again…I see my neighbours buying crate loads of stuff from Taobao and get jealous…

I received the Onirii brakes. I took some pics of how they look and weight vs the ztto I have. I replaced my rear caliper and the cable binding is gone. I was worried the compressionless housing was ruined from the kinking. The cable goes to the caliper without bending over the chainstay. Yay! They are heavier by 10g. I took a pic of the pistons. They are more expensive. I don't like logos in general. If you buy black might as well expect you really got white. Since that's what shows on the right side.

@kbike: How are those Onirii brakes working for you?

I ordered the ZRACE branded BR-005 brakes for my new build.
Paired with Sensah SRX brifters and Jagwire compressionless break housings the break feeling is really good.
So far I have done about 150km with some Swiss "hills" where the breaks were put to the test successfully.
Honestly these breaks feel as good as the Juintech F1's I have on my other gravel bike, so far so good at a great price!
Long term experience will show if they are worth their money.

@ChrisB: Did these come with the 160mm adapters included? And different length screws for the rear?
-
I did order them with the 160mm adapters. Usually you can get different versions at the vendors, just make sure you get the 160 adapters for front and back.
Additional remark:
The calipers are designed so the cables are on the inside which prevent sharp bends when mounted to internal routed frames. This made the break housing installation very easy.

Could you please elaborate more on how they compare with the Juins? in term of initial bite force, lever feel/modulation, heat buildup from prolonged use, etc.
-
I wish I could give you some long term experience but for that I did not do enough rides...
Comparing the BR-005 with the Juintech F1's:
The initial bite and break power feels very similar. I did not experience any fading on longer descents.
A 1:1 comparison is difficult since I am using different Brifters: Sensah SRX vs. Shimano 105.
The BR-005 are combined with Shimano rotors, while I am using light Oniiri rotors with the Juintech F1's.
I will try some A vs. B comparisons when I find time.
In the meantime I will try to get some more rides on the new bike. :-)

I ran the br02 and br05. The br05 bites firmer and stop much faster. They feels much closer to my Shimano hydraulic brakes. I can lock the wheels but need to pull very hard unlike hydros. The br02 feel soft and slow by comparison. I used the same ashima rotors.
I haven't done Hills yet. I really pushed them yesterday in the city with lots of hard stops to see. The br02 scared me one time they couldn't stop me completely before an intersection.
I either have less oil or air in my br02 or the br05 has a better seal. I've boxed up the br02 and will be using the br05. I hope in may to hit more elevation. Wind and cold rain has pretty much described April.

We had a pair of earlier BR-002's in use for about 9 months and the break power was far off compared to the BR-005.
Worst of all, when checking them after a few months in use the left and right pistons did not activate simultaneously which made modulation impossible.
I would certainly not recommend getting the old BR-002 models.

Thank you both. Were you two using the included brake pads? the pads design looks to be the Shimano K03S standard so perhaps some more braking performance gains could be found there

So far I am running both the Juintech F1's and the BR-005 with the original pads that came on delivery.
I am also wondering what improvements could be achieved experimenting with different pads...
Hopefully somebody can share some experience with different break pads and make some recommendations.

You could try semi-metallic pads? they're certainly more abrasive that the stock resin ones. However I remember Juin support explicitly telling me to only use resin pads with the GT-F
It's a bummer Onirii didn't design the BR-05 for finned pads though. K03S is just the non-finned version of L03A which would open up a lot of cool stuff like SwissStop's EXOTherm2 or Jagwire's Elite Cooling. If you want to keep things resin and OEM, I guess you could try the K05S which is the latest in the Shimano K02S/K03S non-finned resin lineage.
-
Just for fun I checked the older ZRACE BR-02 callipers lying around in the basement and shot a short video of the non symmetrical activation of the brake pistons.
Even after cleaning, the pistons do not activate symmetrical. Under these circumstances you can not expect that the brakes work correctly.
I think this is really a systematic problem due to design or quality control.
The BR-05 on the other hand activate perfectly symmetrical, so they seem to have fixed that issue.

I've been dying to change my GTs simply for aesthetic reasons.
Given the price difference and positive first impressions, I picked up a pair as well.
Purchased on Taobao for $85CAD.

Could you give the BR-005 a test already? Could you leave some impressions?
I'm in the planning phase of my CFR696 build and those are the brakes I'm likely going to use. Though I'm a little bit concerned that I'm not going to be that happy with the brake power. (coming from V-Brakes with compression less housings on my old-school graveler.. but I also have 4 piston brakes on my all mountain fully, so I'm kinda spoiled)

That's quite a good hint with the K05S, since K03S seem to be out of stock atm pretty much everywhere where I look.
Sorry for asking and kinda hijacking but the B03S would likely not fit, right? (besides they are using a splint and not a screw to secure the pads)
While I'm at it.. regarding rotor choice: there are shimano rotors designed for wide pads (as B03S) and narrow (like K03S) pad shapes. Would I experience down sides using rotors designed for wide pads but actually using narrow pads? (the other way around would make sense to me to be disadvantageous)

The Onirii BR-05/ZRACE BR-005 is the only viable hydromechanical option in its price bracket. It obviously won't be as good as the 4-piston Juin GT-F but to supposedly perform on par with the 2-piston Juin F1 while costing half as much, what more can you ask for?
I don't think that B03S/B05S will fit. Not sure about the rotors

„TraceVelo“ has noted in his video comparing that the disc-brakes on the cheap models is no rubber seal at the transition from the brake arm to the brake piston but there’re included in the Juin Tech F1…
Are the BR-05 brakes from Oniri with or without rubber seal?

Some update from my side since I put some more Kms on the bike with the BR005s… all good so far but no wet weather riding.
The BR005s have the rubber seal as far as I can tell comparing to the old BR002s.
Comparing to the Juintech the BR005s need more cable pull for activation, however I have different break levers on the bikes…
I can definitely recommend these breaks.

Regarding the versions with exposed pistons, it seems like that was actually the 2nd generation design done by a company called IIIPRO who produced them until Onirii took over the project.
Mine just came in the mail. Interested what your take is on these.
They are branded Onirii on one side, IIIPRO on the other.
They come with pads installed, so I haven’t checked the seals yet.
For comparison, they are 37g heavier than the Juin Tech GT-F for the same 160mm setup.
So torn. Giving up 37g and dual piston calipers for colour coordination…

Yeah the quirky mixed branding (Onirii facing outwards to NDS, IIIPRO facing inwards) is normal on the Onirii BR-05.
Your GT-F is hands down the best hydromechanical option on the market, so it'll for sure be a downgrade in terms of performance.

...Your GT-F is hands down the best hydromechanical option on the market, so it'll for sure be a downgrade in terms of performance.
Just because of the double pistons or there are other design advantages ?

-
Giving up 37g and dual piston, but saving how much money?
None. Because I already bought and have been using the GT-Fs. Lol
But…for all of you still weighing options:
Juin Tech GT-F: $280 CAD. Natively designed for 160mm. 4-piston. Comes equipped with pads, as well as a spare set. Comes with 3 sets of bolts for different chain stays. 332g for the system including mounting hardware
Available on AliExpress
Onirii BR-05: $125 CAD (for 160mm version). Natively designed for 140mm. 2-piston. Comes equipped with pads. Comes with 3 sets of bolts for different chain stays. Comes with some cable crimps. Comes with 160mm adapters.
369g for the system including mounting hardware.
As of posting, only available on Taobao.
A note on Taobao: It can be used internationally, but you need to be able to read Chinese, or have a friend who does. It accepts international credit cards, and shops internationally - at least the vendor I bought the calipers from did.
Buying is a two-step process. First you need to buy the item. This gets you domestic shipping (free in my case) to the nearest port in China.
Once it arrives, you receive a notification to arrange international shipping. If you bought a bunch of stuff on Taobao, you can wait for items to aggregate at the port and have them shipped together. If you have a ton of stuff, you can arrange things to be shipped by ocean freight (at least as far as I could tell)
Most of us will just get Cainiao shipping (or whatever retail option is available). This cost me $40CAD and is included in the price above.
If you don’t pay, the item just sits at the port. I don’t know what happens if you let it sit there forever.
Then, you can sit back and wait for the package to arrive. All in, it took about 3 weeks from purchase to door for me.

Yep. Looks like it is available now. And for less than I ended up paying. Lol
-
so my BR-05 arrived (also got the ONIRII ones). Couldn't test them yet though.
Bad news:they do not use K03S/K05S pads. Ordered them online and they (K05S) are not as wide as the ones that come with the BR-05.
Good news: local bike shop got a part restock and the G03S fit.

Did anybody try replacing break pads on the Onirii BR-05 or Zrace BR-005?
Seems to me that the suggested Shimano G03S are too wide to fit?
I made the practical test and took out the existing pads and could not fit G03S compatible pads since they are too wide.
Instead I found a reference that the BR-05 / BR-005 uses Brake Pads for SRAM DB1 DB3 DB5 SRAM LEVEL T/TLM.
Would like to try some other pads to see if break power can be improved.
Correction:
I measured the break pads installed in my Zrace BR-005 with following values: Height 29.5mm / Width 26.5mm / Pad only height 16.5mm
Result: Should be K04S compatible so ordered some Cooma BP944ExPlus-RS805 to try:

Here pictures of original pads on left and new Cooma pads on right:

After almost 1000km of comparing the Juintech F1 to the Zrace BR-005 the Juintech F1 clearly wins in terms of break bower and low heat fading.
So any improvements by changing the break pads would be a bonus.

So far I am running both the Juintech F1's and the BR-005 with the original pads that came on delivery.
I am also wondering what improvements could be achieved experimenting with different pads...
Hopefully somebody can share some experience with different break pads and make some recommendations.
BR Chris
I'm a bit late to the party! But I did actually run my F1s with Shimano metal pads. When I switched over to the M06 metal pads I immediately felt an improvement. I didn't run this brake set for very long tbh. I quickly switched to a hydraulic system because fully internal routing+cable disc brakes got me into some sketchy situations almost immediately, but the difference in stopping power between the M06 and the stock pads was undeniable. Not up to par with my SRAM hydros, but much better than with stock pads. The metal pads stopped quicker but also produced more noise, though not enough to bother me.
Maybe the braking performance would be much better on another bike where the cables don't run through the bars or headset...I should give them another shot on a bike that doesn't route cables like this, maybe on the gravel bike?

I can confirm your suspicion, paired with compressionless cable housings and non integrated routing (allowing gentle routing radius), the brakes feel excellent and offer great stopping power. With the Juintech F1's I am really happy but the BR-05 / BR-005 could need some extra bite, so other break pads are on the way to test. ;D

Is it possible that there is a difference in break pads between the Onirii BR-05 and the Zrace BR-005?
My measurements on the Zrace BR-005 version show smaller break pads with size K04S / K05S.
Any confirmation would be helpful.

None. Because I already bought and have been using the GT-Fs. Lol
But…for all of you still weighing options:
Juin Tech GT-F: $280 CAD. Natively designed for 160mm. 4-piston. Comes equipped with pads, as well as a spare set. Comes with 3 sets of bolts for different chain stays. 332g for the system including mounting hardware
Available on AliExpress
Onirii BR-05: $125 CAD (for 160mm version). Natively designed for 140mm. 2-piston. Comes equipped with pads. Comes with 3 sets of bolts for different chain stays. Comes with some cable crimps. Comes with 160mm adapters.
369g for the system including mounting hardware.
As of posting, only available on Taobao.
A note on Taobao: It can be used internationally, but you need to be able to read Chinese, or have a friend who does. It accepts international credit cards, and shops internationally - at least the vendor I bought the calipers from did.
Buying is a two-step process. First you need to buy the item. This gets you domestic shipping (free in my case) to the nearest port in China.
Once it arrives, you receive a notification to arrange international shipping. If you bought a bunch of stuff on Taobao, you can wait for items to aggregate at the port and have them shipped together. If you have a ton of stuff, you can arrange things to be shipped by ocean freight (at least as far as I could tell)
Most of us will just get Cainiao shipping (or whatever retail option is available). This cost me $40CAD and is included in the price above.
If you don’t pay, the item just sits at the port. I don’t know what happens if you let it sit there forever.
Then, you can sit back and wait for the package to arrive. All in, it took about 3 weeks from purchase to door for me.
Any side by side comparison between Juin Tech GT-F and Onirii BR-05?

Unfortunately not, I ended up selling the BR-005s.
From what I hear, they are similar to the Juin Tech F1s, which are the single piston version of the GTs.
If that is the case, it is fair to say the GTs are better but more than twice the price. But I would go out on a limb though and say I doubt the GTs are twice as good.
The F1s and BR-005s will work just fine for almost any type of riding and rider you can throw at them

My long term experience with the Juintech F1 vs. the Zerace/Oniri BR-005 are as follows:
Juintech F1's: Excellent braking power even at longer descents down Alpine pass roads with original break pads
Zerace BR-005: Weaker break power with original break pads, after changing to alternative resin break pads much improved... still a bit behind the Juintech F1's.
General recommendation: Make sure to use compreissionless break housings and prevent tight bends (internal routing) for good break power and feel.

.... prevent tight bends (internal routing) .....
BR Chris
I'm afraid of this in my new build with full internal routing.......

I bought the BR-03, after being very underwhelmed by the performance, I got myself the BR-05 for a better performance.
While I tried the brake in road setting (approx 500km) and they are ok, yesterday was my first proper gravel ride and required longer braking down FSRs for a longer period of time. I experienced quite a lot of fading at the end of the slopes where it seems the braking power reduces over time.
This with the announcement in the rotor discussion of the CD-01 and CD-02 that gets discontinued because of issues leaves me wondering if these semi-hydro/Onirii brakes are worth it, or if I should switch to a fully hydraulic groupset (either waiting for Sensah or going with SRAM), or start by switching to different brake pad/rotor combo (recommendation welcomed).
FYI, I have compressionless housing for the rear brake and normal housing for the front brake, and the conditions were very dry.

Hey there,
I couldn't say, as I haven't tried the ZRACE.
Here is a review of the ZRACE and Juin F1s.
The GTs are better than the F1s.
If I had to do it over again, I'd go for the F1s, as the GTs just feel like overkill for typical road cycling (no prolonged descents). Confidence inspiring in rush hour traffic though

I don't like this as it appears to be scientific but their are a lot of uncontrolled factors. Like human reaction, the lack of exact timing, exact pressure put on the breaks, even the how hydrated he is could influence weight. or How hot the rotors started off between stops. maybe even how much he trusted the brakes to pull on them.
To accurately test them with repeatability and to eliminate factors. You would need to make a rig to test them. spin them up to an exact speed, and pull on them an exact amount. and do it hundreds of times. then average out that data. after removing any thing that more than 5% of medium number.
then we are talking about science.

I have 1700 miles on road bike and 750 gravel bike on 2 sets of br-05 calipers. I have a lot of wear on the 1 set. I need to adjust the calipers so there is less play before engagement. On my gravel I've only use them on flatter routes. I kinda expected to here they'd have issues on the tougher descending gravel routes.
I will be buying some upgraded pads off aliexpress to see if they bite better and how long they last.
I just did a full bleed and new hoses on my shimano hydros. The shifters and calipers had zero oil to start. That ended up taking so much time. I still need to put more oil in to get the feel I want. The shimano hydro hoses I used were smaller and more flexible the compressionless. That made running the cables easier and faster. I've used these for my scary gravel rides where 45mph happens and you have bends or tight turns during thought downhills.

Agree, but if you find someone who’s willing to go through all that for the clicks, let me know.
No one in the industry is going to do it (this industry thrives on marketing cherry-picked data and biased studies). So, all that’s left really are highly subjective user experience and uncontrolled experiments…

btw don't get me wrong there are a lot of value in talking about subjective experiences. Because feel is an important factor in riding. take tire size and the psi even. Feel is as important as performance. Though brakes is something I would want the better stopping and feel( break rub or spoongyness)
For all we know the f1s preform better than the tests because he had trust in them and therefore went easier on them.

After longer use (1000km plus), I found the break power of the BR-005 to be lower compared to the Juintech F-1.
I also experienced fading especially in warm temperatures.... after changing the break pads to alternatives, the break performance improved consdiderably. I do not know yet if this also cured the fading on long downhills.
I changed to these Cooma break pads:

No scientific tests from my side, however over 2000km on my Titanium Gravel bike with Juintech F1's including downhill on Swiss mountain passes.
I use the BR-005's on my second gravel bike for commuting and after about 1000km I found a big difference in break performance, a big part seems to be related to the sub-par original break pads on the BR-005's.

I am also finding that braking performance, while initially good, is deteriorating with stock pads on the BR-005. Thanks for sharing your findings.

There is a guy that does amazing testing just need to get him interested. He also buys all the products for testing. He's built and tested gas bicycles. If anyone would test brake calipers he would.

Will Juin tech brakes work the same using SRAM / Shimano road shifters? I know that different cable pull ratios mean you shouldn't mix shimano and sram shifter-brake, but Juin Tech doesn't make a Sram version and a Shimano version AFAIK?
If you have a choice between Shimano and Sram with a plan to use Juin Tech brakes, what should you do?

Shifters need a precise move for each shift.
But they will just brake more if you increase the force on the lever, I don't think there is a special ratio to have.
FWIW Sensah levers work well with F1 brakes.
And are a SRAM like actuation with Shimano shifter pull ratio.

F1 works with SRAM levers as well can confirm.
Agreeing with what you said, though. Any road lever should work fine.

It is confirmed that there are 2 versions of the BR-05 in existence. But all new production post Feb 2022 should be using 32mm pads instead of 26mm.
This info is stated on taobao.
