TEXAS BIKE WORKS, LLC INTRODUCES RetroFrames TM line of vintage Old-School and unique Fusion chopper frames to chopper builders.
The specific Old-School frame shown integrates vintage 1970s small-diameter tubular members with modern-era Sportster motors (1986-2003). The Century Rocket frame is constructed of rugged, 0.120”- wall, AISI 1020 DOM tubing, having 1” frame rails with a 1-1/2” backbone and seat post. Also features a 6” forward x 2” up-stretch x 38-degree rake. This configuration takes a +4 over fork assembly. The frames are set up for acceptance of chain-driven 130mm tires. They are all TIG welded in our patent pending rotisserie style fixtures. This allows the frame to be completely welded in the jig then stress relieved and fixture cooled which minimizes distortion and maintains accuracy.
RetroFramesTM are computer-engineered in SolidWorks CAD software, followed by a corresponding stress/strain-field finite-element-analysis (FEA) performed in COSMOSWorks. FEA graphically depicts the field distributions throughout the frame design – enhancing TBW’s quality assurance goal geared toward top road performance and safety.
