I will tell You a story (true?/false?) :
Bike lies on the ground below/next to the big/long drop in the forest (it's owner takes photos of other riders who dare to jump)
One of them fu*ks up the takeoff and falls next to the landing zone - unluckily on the friend's bike....

So: A Big/heavy guy in a full body armour/fullface helmet/not light backpack/camelback etc... lands on the rear part of this frame...
Is there any frame on the market who could handle this kind of the side forces?....
www.pinkbike.com/photo/7262561 That's how it looked like 2 days before the welding.
Do You see any cracks? ;-)

 was the frame cracked?
