My frame is an Emonda copy, I was able to only have one short 50km ride so far.
Long term experience will need a few more months, but so far so good.
There is nothing crazy in terms of technology on this frame that I would expect to cause any problems.

The only negative is, that it uses a copy of the Trek "seat mast" instead of a traditional seat post. You can not easily find such "seat masts" as separate parts on Ali.
In my case I wanted to fit a saddle with carbon rails but the seller could not offer the adapter parts for 7x9 rails.
Finally I found the adapter parts from Kocvelo on Ali that work perfectly with the clone Trek "seat mast":

I would also be careful with the Isospeed copy, my guess is you need to really understand how that thing works before making a copy.

Thanks for the posting, sounds good, will wait for a long term review

Trek Madone frame Hey there, i'm sorry in advance for all my grammatical mistakes, not a native speaker.

So, i'm really obsessed with trek madone, but because i'm living in country where the official minimum salary is 80$, i was started to looking at rip off framesets, but i couldn't find any review or information whatsoever. I haven't bought it yet, i'm on the path of making investigation about it's quality and reliability.


1) Let's begin with seller investigation, i've found three main sellers on Aliexpress that sells this frame:
Taiwan Eisen https://www.aliexpress.ru/store/5257218
Rocking Cyling store https://www.aliexpress.ru/store/2189015 (one of the forum members bought Emonda frame from them: https://chinertown.com/index.php/topic,4029.msg42719.html#msg42719

And Taobao store: https://item.taobao.com/item.htm?id=694413006667

So, i think there are several manufacturers, at least two, and there a few reason for that, the first one is the frame weight difference is tremendous, 16750 (eisen) and 2045 (taobao), which is huge difference, the second one is that Taobao store have 2023 replica of Madone already, but eisen is planning to release their in April.


2) Frame photos, i collected all the photos from Aliexpress sellers:

Eisen: https://ibb.co/album/LYjQkz
Rocking: https://ibb.co/album/xXdb8d

So, what i learned is that these pictures are low quality, so it's really hard to judge the quality of the frame, i asked sellers to send me high resolution photos, haven't received them yet. But, here are close shots that i already have (all photos from rocking store, waiting photos from eisen, taobao seller didn't want to send high res photos):

BB:https://ibb.co/xMkN9BB https://ibb.co/g7BMn5r https://ibb.co/NjWBXQf
Handlebar: https://ibb.co/9nJFprd https://ibb.co/R3BvkcZ

So, in conclusion, quality is very similar to what Hambini reviewed, Chinarello replica, it has similar problems with BB and some slight imperfection on the stem, but not bad overall.


3) IsoSpeed, many have concerns regarding it, but i made some research, and it's actually a fairly simple mechanism, my most worried part was damper, i thought it was kind of precise and hard to manufacture thing, but in reality it's just a button with (what seems) elastomer: https://ibb.co/MDhYcV5, which is also mentioned on Trek page: https://www.trekbikes.com/us/en_US/inside_trek/isospeed/, so i don't think it's that hard to replicate.


4) Carbon fiber, they claim that they use T1000 CF, i asked them is this a Toray, but haven't received the reply yet.


5) If something breaks by your fault, you can buy replacement parts from seller at least Eisen confirmed that you can.


If there will be more information, i will try to share it with you.

Re: Carbonda CFR 1056 or VeloBuild 177? Yeah... i know about geometry, but i'm so tired to see problems with Chinese frames, so for me it's much more important to get product that have better quality.. regarding VB 168, well i was thinking about it, but Patrick Lino said several times in his review that 177 is stiffer and overall better value.

I'm on a VeloBuild VB-R-168 right now for road and have a 177 on order as I also want to compare the stiffness.

Wow, waiting for your review.

Also i was thinking about ican a9, and i have opportunity to buy it much cheaper (just for 750), but they are using T700 and T800, (i know that it more depends on the carbon layout, than on it's type, but in case of Chinese, i don't think this is always the case, i think it's also wise to relay on CF they are using)

Re: Miraclecycling vs Yoeleo prices Recently asked Mira Cycling is the frames they are making is the same as Yoeleo, well, answer is yes, i think, but for older models, for the new models Yoeleo have partnership with different factory.

OK I pull this thread up again since there were several questions regarding copies of well known frames in the past weeks.

Finally I got some more KM's on the bike and can share some experience after 650km on the road.
The frame is a copy of the Trek Emonda 2022, which is a very accurate clone when comparing details from the original TREK manual.
As you would expect, the frame and components do not come with their own manual, so downloading the original manual is of big help during assembly.
So far everything is performing without issues and the ride feel is one of the best I had from a road bike so far.

Would I recommend a "Copycat" carbon frame?
Having the choice to buy a similar Chinese "open mold" from a reputable Chinese manufacturer it would be my first choice. I believe they will stand behind their quality and maintain good standards.
The risk of a "Copy" frame is the quality of the carbon material, lay-up, lamination and QA, that is not easy to recognize even after using an endoscope camera to check for obvious flaws...
With some experience building up Chinese bike frames and for me personally it is a reasonable choice.

BR Chris

Thank you for your review! What's quality from the inside compared to the open mold brands? Like thickness, cleaness, voids and other factors

Re: dcrf26 frame - Scott Foil? For everyone who's wondering, there are differences between Scott Foil and TanTan x38 geometry:



1) Top tube is more parallel to the ground, which leads to higher seatube, bigger rear triangle and probably more stiffer and harsher frame
2) Fork is a little bit thinner (like for 15%)
3) BB area a little smaller in height

Also yes, the frame support 160mm disc with adapter.

105 DI2 bike for 1550$ Hey there

Just found this bike: LINK on Taobao, seems to be a very good deal, i coudn't find their frame, so it's probably not an open mold.
