Synchro violin block with clamp

Synchro violin block with clamp Lewmar's Synchro series is the result of a complete rethink in block design. This series transforms performance levels into speed, efficiency and handling. Scientifically optimised block geometry, a revolutionary free-spin bearing and a self-aligning block head reduce friction and improve efficiency by up to 40% compared to a conventional mainsheet system. The result is that every component is synchronised with the movement of the rope - a light, smooth transition of power from deck to sail - all with less wear on the sheet/fall.
