1. Understanding the different types of rope

Single ropes

Single ropes are probably the most common type of rope used in sport climbing. They are used for ascents where the climber is secured directly to an anchor point at the bottom of the route. These ropes generally vary in diameter from 9 to 11 mm and in length from 30 to 80 meters. The choice of diameter and length will depend mainly on the type of route you plan to climb. A thicker rope will be more durable and abrasion-resistant, ideal for rocky routes or intensive indoor use. On the other hand, a thinner rope is generally lighter and offers better maneuverability, which is an advantage for high-level performance, especially during redpointing or competitions.

Double ropes

Primarily used for mountain climbing or adventure terrain, double ropes offer increased safety on uneven terrain or where there is a risk of falling rocks. They also reduce draft and are essential for long routes requiring abseiling. These ropes are thinner, generally between 8 and 9 mm, and are always used in pairs. Choosing a double rope means taking into account wear resistance and the management of both strands, which can be more complex but offers greater versatility in terms of route management.

Twin ropes

Twin ropes are similar to double ropes, but must be used and clipped together at each anchor point. This system is less flexible than double ropes, but offers excellent shock resistance, making it ideal for demanding routes over unstable or icy terrain. Their use is less widespread, but can be a wise choice for specific alpine expeditions.

2. Key selection criteria

Durability and surface treatment

The durability of a rope is essential, especially if you climb frequently. Surface treatments such as dry treatment improve the rope's resistance to water and dirt, prolonging its life and maintaining its performance in a variety of conditions. These treatments are particularly important for outdoor climbing, where ropes may be exposed to damp environments.

Shock force and number of falls held

Shock force indicates the force transmitted to the climber and anchor points in the event of a fall. Lower shock force means more efficient absorption of fall energy, increasing comfort and reducing the risk to anchor points. The number of falls held, standardized by the UIAA, is also an indicator of the rope's robustness in the face of extreme stress.

Flexibility and handling

A more flexible rope is generally more pleasant to handle and easier to tie knots in. However, it may be less durable. Finding the right balance between flexibility, weight and durability is crucial for experienced climbers.

3. Practical tips for caring for your rope

Cleaning and storage

It's important to clean your rope regularly to remove dust and sand particles that can accelerate wear. Use lukewarm water and mild soap, and leave to dry in the shade. Store your rope in a dry place away from direct sunlight to prevent UV-induced fiber weakening.

Regular inspection

Before and after each use, visually and manually inspect the entire length of the rope for cuts, worn areas or damaged inner strands. This is essential to ensure safety during your ascents.

In conclusion, the choice of climbing rope should be made with care, taking into account your climbing style, level of practice and environmental conditions. A well-chosen rope is an investment in your safety and performance, and regular maintenance will ensure its longevity and efficiency.
