Mechanically-speaking, Link Cams are as innovative as the concept behind their design. Built with a hybrid blend of materials and advanced MIM process, Link Cams are the most sophisticated and modern camming devices in the world. The two inner links on each lobe unit are built with a very new (and very expensive) process known as Metal-Injection-Molding which permits Omega Pacific to create detailed, precision pieces - like casting - with the strength of machined parts that are made from 17-4 aircraft stainless steel. The outer link is machined from 7000-series aluminum alloy. Four sizes available .5, .75, 1 and 2. Link Cam #.5 Range 13.5 - 35.0 mm Strength 8 Kn, Weight 95 g, Length 164 mm, Width 46 mm.
