I can confirm that combo PassQuest + PES P505 + Ultegra 12spd + T47A works and shifts well

Well, I think this is gonna be a difficult one. Their answer is obviously bullshit, but on the other hand they can always claim it was a user error - e.g. overtorquing the bolts.

It’s an Airwolf YFR 066 frame with a threaded ZTTO BB86 bottom bracket, but I don’t think this is the cause of the issue. I even tried fitting the Pass Quest chainrings on the Shimano crank, but it won’t shift up.

The first problem with the Magene and Pass Quest combination was that the adjustment range was insufficient, and the screw to adjust the Di2 derailleur was too short. To fix this, I made a 2mm thick plate that went under the front derailleur hanger. This allowed me to adjust it perfectly in the app, and I also tried fine-tuning it several times using the shifters. However, despite multiple adjustments, I still couldn’t get it to shift up.

Interestingly, the first time after installing the groupset, it somehow worked quite okay for a while. Since the derailleur is perfectly adjusted but still won’t shift, my guess is that the gap between the small and big chainring is somehow out of spec, or there is an issue with the tooth pattern on the chainring. With the Shimano chainring, it even shifts properly without being precisely adjusted.

It is indeed weird, because setup with Shimano cranks seems fairly common. Passquest website even advertises this setup. Would you mind posting a photo of the chainrings?

Maybe try reading it one more time, and the conversation that it is part of.

Because nobody is expecting or asking for any protection or guarantee.

Yep... And that goes back to my thread about not buying fakes because of how shady the whole thing gets the moment you start asking questions... If i spend 500$ on a frame, I ask questions. If i am asked to shell $1000, i ask even more questions

I see where you're coming from, and I understand why you hold that perspective.

You're likely looking for technical details, but that depends on whether the sellers are directly involved in manufacturing or just third-party resellers. For the same reason, my local seller probably couldn't answer detailed questions about frame production. Even with well-known Western brands, you'd likely not get more than, "that's proprietary information." I get that those brands have already built a certain level of trust. But when buying a frame from Asia, there’s always some degree of risk. You never really know if the answers you get are accurate or just what the seller thinks you want to hear anyway - and that applies not only to those selling fakes (e.g. Winspace telling the guy that the disgusting BB is ok is a good example)

My perspective is much more cynical - I am suspicious of the answers regardless of the seller. Perhaps it's the experimental scientist in me, but ultimately all we can rely on is empirical testing and first-hand experience with a reasonable sample size is what really matters imo. At the end of the day, it all comes down to how much of a gambler you are.

Edit: That is why people like Pat above are such a fantastic resource

I might seem suspicious, but the snippet on Pinarello seemed suspicious. They show the test on a counterfeit frame, but then show the result on another frame

It was quite a weird video for me. Obviously, there is a massive conflict of interest. It would be unreasonable to expect Pinarello to say "sure, buy fakes/Chinese frames, they are (mostly) safe," they must protect their business.

Some other questions that were popping up in my head during the video were - did they really buy a fake for 3-5 second appearance in the video? Or do they regularly buy fakes? Did they really show a fake or just a result of a random QC fail in their department?

I find these videos of little value, not because I believe that all Chinese frames/fakes are inherently safe, but because of a very clear conflicts of interest which must determine the narrative.

Yes, I understand there was a Chinese New Year holiday. However, according to the Aliexpress tracking information, it arrived in the U.S., cleared U.S. customs, and was handed over to a local delivery company on Jan. 23, which was almost a week before the Chinese New Year. The lack of movement for nearly a month now is unacceptable for a shipping charge of $132.

Did you consider calling the local delivery company?

Is it just my impression or everyone who has not received their frame is in US? Is there anyone from US who successfully got a frame from FC or RK?
