It is an engineering fact that the triangle is one of the strongest structures for support. Girder front ends get their name from the classic structural shape of the Girder Truss or Girder Beam, which was used in bridge and roof construction since the 14th century. They were easy to manufacture and could be constructed in a very wide variety of shapes and sizes. The girder front end is one of the earliest types of both bicycle and motorcycle front suspension. This is what I chose when building my Hardtail Sportster. Compared to springers or telescopic, girder front forks are both lighter and stronger, and relatively inexpensive to build or buy. Cracks, for instance.A girder front end is an excellent choice for a custom bike build. So always check the springs-especially with regard to the earlier Druid type forks that effectively hang on the spring. A breakage could, at worst, lead to a collapse and cause the front wheel or front mudguard to slam into the frame leading to a total loss of control. So take advantage of strip-downs and restorations. I also inspect all threads and lugs-both of which are easier to repair effectively when the forks are off the bike. I give them a good rattle and listen for rust particles-or larger pieces-moving around inside. I feel the tubes and lugs searching for damage. When I get a set of forks in for repair, I check them in a variety of ways. Your ears can tell you a lot if you just listen carefully. When forks have been abused like this, they need to be stripped and have the worn surfaces built up with weld. In fact, all it does it mask wear and it damages the side plates. You need to watch the upper spindle areas and listen for any clicking. I make front wheel spindles too where required. There were various jigs to be built and equipment to be sourced.Д«ut girder forks are my core business. My older brothers all had British motorcycles, while I had Italian machines mostly.
