Essential Connections!

As with the seat tube to bottom bracket connection, it is alway important to have the tube that is under the most severe load be completely welded to the next tube when tubes overlap, or are a tight fit as this head tube junction is. As you can see, the down tube is completely fusion welded before the head tube is installed into the fixture. This is to insure that there is no break in the weld between the head tube, down tube and the head tube and makes for stronger more reliable bike. I choose the down tube to do this over the top tube because it is under a lot more load than the top tube.
