Home -> Sailboat -> Blocks -> Blocks->50mm Synchro Blocks
Lewmar's Synchro blocks are more efficient, less expensive Lewmar's Synchro blocks combine geometry, sheave ratios and a unique free spin bearing, to deliver performance that’s comparable to ball and roller bearing blocks used in pro racing—at a more affordable price. Synchro blocks provide the optimal ratio between line size, sheave diameter and the interface between rope and sheave. This new range of blocks transforms performance, not only by improving efficiency, but also speed and handling.
