Lewmar 90mm Synchro Blocks
Lewmar 90 mm synchro blocks are engineered for speed, efficiency and superior handling. These blocks suit a range of purposes from performance cruising yachts to specific high-load low-movement applications on racing sailboats. 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.
