I took the first trial frame and loaded it to failure. It took a lot of force to get it to fail. In most cases it took almost double the load I've applied in the past to cold set OX Platinum frames and accidentally destroy an S3 frame. For example, the side load test where the head tube is supported, I was suspending my full body weight on the end of a 4' bar and bouncing slightly. Is the frame "strong enough"? It's hard to say yet but this does give me confidence.
