Chances of it cracking in two are slim
Ummm bollocks. This is really poor advice and possibly ruddy dangerous, I havn’t joined in the Kasae bashing before but this is really quite a dickhead thing to say, what exactly do you know about fatigue to say this Kasae? I’ll tell you, eff all.
Thats is a stage two crack, its growing, and it’s going to end in fracture, and it will be messy(OK the crack in theory could arrest, but it probably won’t). Don’t ride it any more. You could try welding it, but if it was heat treated post weld then your weld will be pretty poor compared to the manufacturers original, but it’s worth a try, just monitor the weld carefully after although I wouldn’t do this, just accept it and get a new one. Paint looks in good nick, is it a new ish frame or has it been powder coated/painted?
I think that what I said is accurate, the chances of the frame cracking in two are slim, first you would need to go through the rest of the top tube and then the bottom tube as well.
I also said I would be looking for a new frame and a few other things, however those don’t fit your argument and you don’t get to be right if you mention them and put what I said into context, so just ignore them!
In my opinion it would be very difficult for that frame to completely snap in two, but I would be looking for a new frame anyway.
You’re a legend mate, in your own mind anyway 🙄
