Utilizing a newly developed manufacturing technique never-before seen in the offroad chain market, ProTaper Pro Series chains feature innovative forged pin collars that have been seamlessly incorporated into the outer chain plate. By cold-forging pin collars to encase the thermally refined, chromium carbide layered pins, outer chain plate thickness can be slimmed to reduce weight while increasing tensile strength. Featuring Slim O-Ring Technology, which offers superior, long lasting chain lubrication in a slimmer profile, eliminating the clearance issues of competing O-ring chain designs.
