Ronstan Shock Review

Let’s Talk About Ronstan Shock

The Ronstan Shock is a sheaveless block, designed for lightweight, high-load applications where traditional pulleys might be overkill. Ronstan, a name synonymous with quality sailing hardware, offers the Ronstan Shock as a durable, maintenance-free solution for various rigging needs. This seemingly simple piece of kit promises exceptional performance in demanding environments.

I first encountered the need for something like the Ronstan Shock while working on a custom paragliding project. I needed a small, lightweight, and reliable deflection point for control lines, and traditional pulleys were too bulky and prone to failure from sand and grit. The promise of a sheaveless block that could handle significant loads drew me to the Ronstan Shock.

Upon receiving the Ronstan Shock, my initial impression was one of surprise at its size and weight. It’s incredibly small and light, yet feels remarkably solid. The anodized aluminum finish looks durable, and the smooth, rounded edges inspire confidence.

Compared to traditional micro-blocks from Harken or even simple fairleads, the Ronstan Shock offers a unique advantage. Standard blocks have moving parts that need maintenance, while fairleads, though simple, can create significant friction. The Ronstan Shock offered a compelling middle ground: minimal weight, high strength, and no moving parts to fail. I also considered using a low-friction ring, but the integrated webbing attachment point of the Ronstan Shock proved more convenient for my specific application.

My first impression was definitely excitement. The Ronstan Shock seemed like a clever solution to a problem I’d been wrestling with, and I was eager to see how it performed in the field. Its minimalist design and robust construction suggested it could be a real game-changer.

Real-World Testing: Putting Ronstan Shock to the Test

First Use Experience

My initial testing ground for the Ronstan Shock was the paragliding project, specifically the brake line deflection system. I used it to redirect the brake lines, which experience significant tension during turns and maneuvers. The coastal environment also provided a good test for its resistance to salt and sand.

The Ronstan Shock performed flawlessly in various conditions. Even in strong winds and with sand blowing, the line ran smoothly through the block without any noticeable increase in friction. Its lightweight design didn’t affect the paraglider’s handling, and it remained securely attached to the webbing.

The Ronstan Shock was incredibly easy to use. Splicing the line and attaching the webbing were straightforward. I didn’t need any specialized tools or techniques.

Initially, I was concerned about the potential for line wear, but after the first few flights, I noticed no signs of abrasion or damage to the line. The smooth, rounded surface of the Ronstan Shock proved to be gentle on the line.

Extended Use & Reliability

After several months of regular use, the Ronstan Shock continues to perform exceptionally well. It has become an indispensable part of my paragliding setup. It is regularly exposed to UV rays, salt spray, and abrasion from sand, and it hasn’t shown any signs of degradation.

The Ronstan Shock‘s durability has been impressive. Despite being subjected to high loads and harsh environmental conditions, it shows no signs of wear or tear. The anodized aluminum finish still looks like new.

Maintaining the Ronstan Shock is incredibly simple. There are no moving parts to lubricate or replace. A quick rinse with fresh water after each use is all it takes to keep it in top condition.

Compared to my previous setup, which involved using small pulleys that required regular cleaning and lubrication, the Ronstan Shock is a significant improvement. Its reliability and low maintenance have made it a much more appealing option. It has far exceeded my expectations.

Breaking Down the Features of Ronstan Shock

Specifications

• The Ronstan Shock accepts lines from 1.4mm (1/16″) up to 8mm (5/16″). This versatile range makes it suitable for various applications.
• It is designed for 3/16″ line and 1/4″ webbing. These are common sizes for control lines and attachment points.
• The Ronstan Shock‘s height is 8.5mm (5/16″), width is 14.9mm (9/16″), and length is 22.9mm (7/8″). These compact dimensions minimize weight and bulk.
• It has a Maximum Working Load (M.W.L.) of 175kg (385lbs) and a Breaking Load (B.L.) of 350kg (770lbs). These high load capacities ensure it can handle demanding applications.
• The Ronstan Shock weighs a mere 2.5g (0.01oz). This ultra-lightweight design is crucial for applications where minimizing weight is essential.
• It is made from anodized aluminum. This provides excellent corrosion resistance and durability.
• The Ronstan Shock is color-coded in blue. This allows for easy identification and organization.

These specifications are critical because they directly impact the Ronstan Shock‘s performance and usability. The high load capacity and lightweight design make it ideal for applications where strength and weight are paramount. The anodized aluminum construction ensures it can withstand harsh environmental conditions, while the smooth surface minimizes line wear.

Performance & Functionality

The Ronstan Shock excels at its primary function: providing a low-friction, high-load deflection point. It allows lines to run smoothly and efficiently. It also minimizes wear and tear, all while adding minimal weight to the system.

Its strengths lie in its simplicity, durability, and lightweight design. It works perfectly as intended, providing a reliable and maintenance-free solution. Its only potential weakness is that it’s not a true block with a rotating sheave, so extreme angles could increase friction compared to a bearing-based pulley.

The Ronstan Shock has exceeded my expectations. It has proven to be a valuable tool for my paragliding project and other rigging applications. Its reliability, low maintenance, and lightweight design have made it an indispensable part of my kit.

Design & Ergonomics

The Ronstan Shock‘s design is minimalist and functional. Its smooth, rounded edges and compact dimensions make it easy to handle and integrate into various systems. It is incredibly lightweight, barely noticeable in use.
