The E3 process yields the higher weld strength by exposing more surface area on the end of the tube prior to welding. Most companies don’t grind this extra metal off before welding. Only the thin edge of the tube is welded. Not the full thickness of the tube.
Notice the difference between the industry standard pre-welded tube and the E3 tube. When welding the industry standard tube, the weld only penetrates the thin edge and not the full thickness of the tube. The E3 tube allows for the weld to penetrate the tube fully. Our tests show welds that are 3 times as strong as before. Stronger frames mean safer riding; and we’re all for that.
We’re constantly experimenting and exploring better manufacturing methods. This has led us to completely revamp our manufacturing, to stress quality and performance. E3 is the next wave of BMX.
