The giant does have a weld there. The weld isn't the issue. It's the filler covering the weld is not flexible enough. Cosmetic issue, not structural
Giant reign 2022 frame cracking

I keep reading this thread and I am intrigued just what weld process was used. I really cannot believe the "filler" referred to is something like fibreglass or epoxy. The fact that Giant are apparently changing frames on warranty for what is refers to as cosmetic damage also infers the "filler" is a metallic one which would not be possible to repair.
The only relatively new welding process I am aware of is a method used to enable welding of 7075 alloy ( normally not possible to weld). That process involves laying thin wires of magnesium carbide across the weld area before welding. They refer to those wires as "filler" and it is presumably impossible.....as per all stick, Tig or Mig welding....to have a finish such that you cannot see the weld.
I wonder if it is in reality not a weld at all in the accepted sense........ie 2 components joined together by melting both the edges of each part and a filler rod/wire. I know of other structures (e.g. windsurfing boom consisting of a mix of 7075 and 6061 ally sections) under similar or even greater stress than a bike frame that are in fact bonded (glued) . That looks like what may have been the case on the seat tube failures on the Orbea Wild since there is no sign of a weld on the parts when separated.
All very intriguing! ( ps not for me........I want to see a well executed TIG weld!!)

If you look at the thickness where the cable ports are it’s obviously some sort of “bog filler” at the bend. Nothing intriguing

hey bro got my one from the black shop that starts with an E
Gota say they have been really good lending me a bike in the meantimeWhat is concerning rather than intriguing is that most photos on here show a very straight line as a crack. That suggests separation of the joined sections rather than twisting or at that section of the frame.. I have used epoxy filler on cars and windsurf kit.....never seen a repair crack in a perfectly straight line.
Depends on the flex point. Cars etc won't have flex points like on a down tube. It's been said 100 times now it's not structural. Mine shows signs and going morzine with it as been told it's fine to.

Agree on this, the filler doesn't just crack without movement/flex. I still have no doubt these frames have a design flaw, there is no crack without movement between the tubes.
Ah wicked, they were my first choice and actually gave me a really good quote on the Trek Rail 5 which was my 'plan b' bike if I couldn't get hands on the Reign. First couple of rides last weekend and I'm beyond impressed with it!!hey bro got my one from the black shop that starts with an E
The frames do flex. Its intended. Carbon frames as well. If they didn't flex at all it would be horrible to ride. The issue is the filler doesn't flex, when it should have some Flexibility.

E+ 1 Good Grey. Waited for my replacment frame almoast five months and have been told the only option is green frame. However, I favor Phantom Green anyway 
Hope I will not face any cracks as it is cumbersomw and on my bill to wrap the frame.

Crazy mate! Make sure it’s the update version then.
It is. Maybe just some countries getting all colours in latest model. I'm in the UK.

Its been about six weeks since I contacted my bike shop and five weeks since I posted a photo of my frame crack in this thread.
Today the bike shop responded in writing as follows. "Giant will replace your frame but say that it’s the paste that they put over the welds that cracked. It will still be replaced but in the meantime your bike is still safe to ride. "
This thread provided me with much valuable information so I was in the loop even before Giant responded directly to me today. So thanks to all that posted.

If it is now a standard Tig Weld in that area on the new frames it is good news.....it may also suggest whatever " new welding process" they used previously does not work...which does not support their contention that any crack is merely cosmetic.

Its a filler and paint issue which they are solving by going to a different welding process. Giant told me in writing it's a problem only with the filler and the bike is safe to ride until the replacement frame comes.
