All Goya extensions use the super strong pin and collar system and come with a proven stainless steel power pulley and cleat. The RDM extension comes with a stepped hole layout to minimize weakening the shaft.
These extensions offer the best weight to stiffness ratio, light and incredibly strong. Optimal block-to-block geometry and reduced friction are provided by aligning the pulleys of Goya sails to the pulleys of Goya extensions. All Goya extensions come as Universal Pin (Euro) models, designed to be compact and sleek.
