Eastern Tramp BMX Frame
Eastern's newest frame is ready to trample the streets, park or trails
Lightning Rod Tubing is a little something that we have been working n for a while. This isn’t some tubing we bought and just slapped a name on we had it computer engineered. Then after rigorous tests we finally gave it the go-ahead and this is what we proudly offer you. It’s a great way to keep your bike light while retaining the strength you need. Its thicker where you are more likely to dent it and thinner where you’re not
Offset butted, and butted end to end and then bulge butted at the headtube to slightly ovalise the tube, this dramatically increases the strength of the headtube/downtube junction. The bulge butt gives more welding area on the headtube and also provides more stiffness.
The tube is 1.8mm where the gusset normally would be on the bottom and the 1.4 mm on the top near the headtube, it then buts down to 1.2mm thick on the bottom to prevent denting and .7mm thick on the top where the tube does’nt normally get hit to reduce weight. The manipulation of the tube provides better dent resistance, a 20% reduction in weight compared to a normally butted tube, and more strength.
