“We’ve always been fans of Buell’s work,” says Magpul’s Mike Mayberry. “He’s a guy who’s never been bogged down in convention. We try to think that way, too.” Part of not bogging down consists of moving quickly, and Mayberry—who’s an industrial designer with experience building mountain bikes—penned the girder fork and had it ready to ride on the prototype machine in just two months. Computer modeling and finite element analysis allowed him to design the parts, then have them produced in aluminum using a high-tech version of lost-wax casting by another Midwestern company. Even with the coolant radiator mounted to it, the Penske-shock-controlled fork weighs about the same as the conventional fork it replaces, Mayberry says, but it gives the Buell even better handling and suspension action thanks to rising-rate linkage and a bit more trail.
