Lewmar synchro blocks are engineered for speed, efficiency, and superior handling. We use a combination of scientifically optimized block geometry, a free-Spin bearing, and a self-aligning head to reduce friction and increase efficiency by up to 40% over budget blocks on mainsheet systems. This means each component is perfectly synchronized 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.
Lewmar's Racing Blocks represent the pinnacle of our standard block range. Manufactured from the best materials, they offer incredible strength-to-weight ratios.
