Re: Tantan Seraph FM699 issues It is hard to tell from that pic but I am assuming that is a carbon recess and not an aluminum race?  If it is a carbon recess then for me it does not appear to be a problem. Your headset will have a metal cup that will press into that recess and the bearing will then sit into the cup, the metal cup spreads the load.  That said, I would be looking from the top down into the headtube to make sure that is is only a small issue and it is not a problem around the whole of the bottom section, if that makes sense. The bottom section is often formed by bonding a smaller carbob tube into the layup of the bottom section of the headtube.  If that hasn't bonded properly then it could lead to a much bigger failure later on.

Either, it is a shame that this sort of thing slips through the QC process.

Re: Tantan Seraph FM699 issues If you're talking about the small 'hair' void/crack in the race cup - would suggest it's likely fine. How deep is it?  If you are worried about it, a bit of carbon fibre friendly epoxy pushed into the void, then gently sanded to smooth the surface would be an appropriate fix.

Re: Tantan Seraph FM699 issues I wouldn't be happy to see that on my frame, but I would ride it anyway.
As suggested plug it with epoxy, if you are worried.

Tantan not winning points... again  ::)
Each time I want to give them a chance for a hardtail, a story like this pops up.

Re: Tantan Seraph FM699 issues Yeah that doesn't look good.

Have you sent them photos of that as well and if so, what have they said to this one?

If they still won't replace the frame then is the oval too small or too big at the widest part?  If it is too small then it might be possible to rescue it with a drum flap sander / flap wheel.  Not ideal, and also expensive but just a thought.  Also, if you bought from Aliexpress and the seller won't come to the party then I would be opening a dispute. That's two pretty poor QC issues.
