Rock Lobster frames are built using a variety of materials and methods. While most frames are TIG-welded, fillet brazing and lugged construction are available on most steel frames. Almost any degree of artistic touches are available as well, depending on budget. All aluminum frames are TIG welded and then artificially aged or heat-treated by an aerospace quality facility. Frames are aligned to within .020. Steer tube sizes of 1 and 1 1/8 are available on road and mountain frames. All threads are English and all frames are fully prepped before leaving the shop. Both powdercoat and wet-paint finishes are available, the stock finish being a powdercoat ( single color ) with a wet-paint clearcoat is included in the price. All sizing and geometries are custom as these frames are built one at a time.
