Ronstan Shock for 1,4 - 10 mm rope

 From simple off the beach dinghies to massive foiling multihulls, today’s yachts and the systems for rigging and controlling them are more varied than ever.
This diversity creates unique demands on the hardware which are nowhere more apparent than in the category of blocks. Ball and roller bearings can still provide the lowest levels of friction, but in many applications and environments, strength-to-weight ratio, durability and simplicity are the key requirements. These applications have seen the evolution of apparently simple products, whose outward appearance belies the exacting engineering and advances in materials technology that they are based on, and which still deliver excellent free running performance. Custom made low friction rings and solid fairleads have filtered down from Grand Prix racing to the realm of recreational sailor.
