LewmarLewmar 60 mm Single Becket Synchro Block


The Lewmar 60mm Single Becket Synchro Block is engineered for speed, efficiency and superior handling. Lewmar uses a combination of scientifically optimised block geometry, a Free-Spin bearing and self-aligning head to reduce friction and increase efficiency by up to 40% over budget blocks on mainsheet systems.

Each component is perfectly synchronised with the movement of the rope, providing you with an easier, smoother transfer of power from deck to sail and less wear on your rope.
