Synchro Blocks

Synchro Blocks - Overview

Lewmar synchro blocks are 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 part is perfectly synchronized with the movement of the ropes, providing you with an easier, smoother transfer of power from deck to sail and less wear on your rope.
