Did you decide if you contact them vs dispute? I ordered 400x120. I will make sure to measure the bar once I have it.

Yep, I decided to just opened up a dispute on Aliexpress. I had such a bad time communicating with Seraph, I didnt want to bother.

Funny enough, after I submitted the dispute - Seraph immediately reached out and tried to settle for $20 USD  ::). Kind of insulting lol. Ill let Aliexpress step in and roll the dice with the dispute outcome.

Does anyone know what the maximal tyre size is?
Acording to the webpage its 30? But the real one has 32.

the guy who just go it, have it with a 32inch but actual measure is 35inch 3mm gap, so maybe 32inch with good inner width might fit.

Hi,

I come to you again regarding my experience ordering from Seraph Official Store.

It has not been a pleasant exchange so far and I wanted to untangle the net with the seller but as customer protection and return window is closing, I'm choosing to speak, and see.
I ordered, on the 18 august, the frame in black, 49cm.
As soon as i made the order, asked for "can i change to size 52 and 110 380mm handlebar?" and seller said yes.
Seller also asked to extend shipping time, for production reasons, wich I already did because I know how this works.

on 09/01, he sent me tracking link.

In the meantime, I asked for thru axle size, wich he never really gave me, only products link and "i'll give you later" (why I asked it to Joey)

I received the frame the same day as Joey.

Mounted the bike on the same day. took me around 2 hours to build it properly (no bar tape yet, few adjustments.) took it for a ride and everything felt great (what a beast).

BUT

The handlebars 110-380 (correct size) are so flimsy it's incredible. I push hella watts and this is NOT a viable option, safe too. the GPS mount is so feeble I can see the GPS bending in excess of 1.5cm down when i take speed bumps. That' a real no-no. The D-shaped steer tube is flexy too, so that makes the handlebar bend extremely in the front. I AM SCARED SHITLESS when going fast.

It has something to do with the fact that my position changed and went from ltwoo with great hand retention to Wheeltop, wich has less hand retention.

All of this can be mitigated with the fitting of a new HB wich was always assumed right of the bat.

BUT front tube is NOT the same as factor original (it's thicker) so... this issue is for later tbh



Major issue is:


FRAME'S GOOFY AF

I mean, I'm no stranger to defects on frame and always thought QC was a thing BUT IT IS NOT. Just look at the pictures and laugh at me. I won't even explain how much wheels, driveside change, measurments went up to always get the same conclusion.

Pictures will talk for themselves. Seller thought 30$ refund was safe. I work as a bike mechanic in Decathlon, that's an instant refund.

I'll let you discuss.

Thank you for your reading.

Also I don't recommend buying it, BUT it's perfectly well made inside as well as Joey's, paint is great, everything outside the wheel fit snug, UHD is perfect, T47A assymetric is NEEDED.




for those who don't get it back wheel is sideways

Didn't you just switch the endcaps of your rear wheel?

Can you share a picture of the headtube? Prefereably front on so that we can see how thin it is in comparison to the real frame.

Did you felt any weird ride feel with the Wheel offset like that?. is it noticeable? aside from the handlebar do you notice any other weird feeling?

Thanks for the reply and for the suggestion!

I've been through 3 wheels (proven ones) and switched from driveside to disk side. All wheels have a good center (checked with "parapluie" tool (in french))
The wheel (and only i can see it, no camera even my 300mm zoom can capture it)
Is tilted. It's doing an "x" with the front one.

Thanks again, but no dice sadly  ;D

Heya!

I'll do picture time tomorrow

No issues with udh, replaced it with some I had, same old issue.
With some basic trigonometry I determined that i needed to displace hole 0.9mm further up.

Gravity will keep the wheel in place, although i have to fill the ovalized space for rigidity.

Everything is back in place straight et than ever. UDH hole was too low. Tolerance was over the moon. Hambini would've cried.

Thanks for ideas and suggestions.

Waiting for Seraph reply, holidays incoming.

Not entirely sure if I understand the issue perfectly, but here is a photo of my frame with a laser level. I am not seeing too much deviation.

Also, re:handlebar dispute.

Seraph on Aliexpress offered me a $20 refund for the wrong handlebar, I declined and said to go through the Aliexpress dispute process...to which they graciously bumped up their offer to $30. What a deal!! /s

Aliexpress ended up offering me a 20% partial refund as a dispute solution (~$120 USD). I tried to ask for more, but they seemed to have misinterpreted what I said and just refunded me the 20% lol. I might push some more later, but at least its enough to buy a basic set of handlebars. Mind you, I have spent thousands of dollars on Aliexpress with few disputes, so maybe they are more lenient for me. I've heard of horror stories where people dont get anything in the dispute. Im just sharing my experience with you guys.

For prospective buyers, be ready for lots of communication headaches  ;D. I HIGHLY RECOMMEND buying from Aliexpress for some extra customer protection and use Paypal (Seraph doesnt get the money until Aliexpress marks the order as complete). Oh, and record the full unboxing on video (clearly show the shipping label in the video). That will be extremely useful for dispute proof.
