All of our frames have internal gussets. This is a very expensive and at the same time very effective technology. In the picture on the left, you can clearly see that the inner gusset is twice bigger than the outer one. They effect the strength even more.

The inner gusset is not exactly a gusset. In fact, the tube is milled in a special way, which allows us to leave the right amount of metal only above the top tube and only under the down tube. This way, it adds strength and reduces weight.

If you have been riding a BMX for a long time, you probably saw a lot of broken frames in the spot where the seat stays are attached to the top tube. But we guarantee that there was not any STRS frames among them, because we’ve been putting a gusset between the seat stays since we had made the very first frame. This gusset not only makes the rear triangle much stronger, but also helps to redistribute the load from one seat stay to another one, to the standover and to the top tube.

The Bespaliy brothers love the crankarm grind, and the crankarm grind likes to leave big dents on the down tube of the frame. To solve this problem once and for all, we heat-treated the down tube. And to prevent cracks on the junction of the heat-treated tubes (the BB and the headtube are also heat-treated), we added an additional inner gusset to the down tube.
