The Ronstan Blue Sheavless Shock has ultimate durability with no moving parts shocks provide ultimate durability and are maintenance-free. They are ideal where sand and grit would compromise a bearing system or where regular flushing out isn't possible. Their gentle 3-dimensional geometry is kind on lines but is strong enough to cope with poor leads.
It will be the best choice for those kitesurfers, paragliders, control line deflections, and purchase systems that require a lightweight high load capacity block.
Designed primarily for soft attachment spliced to a line end or lashed in place. The elongated attachment aperture is also ideal for webbing attachment, ensuring the intended orientation is maintained.
It creates unique diversity 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. Custom-made low friction rings and solid fairleads have filtered down from Grand Prix racing to the realm of the recreational kiters.
It has 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.
The applications for SHOCKS are virtually limitless, including numerous high-performance dinghy and small sailboat rigging applications including tweakers, vangs, trapezes, cunninghams, barber haulers, and kite bridles. They are also handy on larger boats for uses such as lazy jacks, sail covers, tie-downs, ladders, and motor hoists.
At a mere 2.5g (0.1 oz), SHOCKS are outstanding performers in the strength and weight stakes. The clever design and exacting finishing also provide excellent free running at moderate changes of angle. Small & hi-tech line specialists SHOCKS accept lines from 1.4mm (1/16") up to 8mm (5/16") and function just as well with hi-tech uncovered braids as with traditional double braids. Available in blue color choices to help keep complicated rigging configurations more organized.
