Smaller diameter ropes are lighter and easier to clip into protection, making them more popular for high-end lead climbing and glacier travel. But shorter ropes will weigh less and take up less space in your gear bag. For many new climbing routes you need at least 60 m, and in some areas even 70 m. Climbing ropes are divided into Static and Dynamic ropes. Static ropes have a high wearing quality and breaking force, they won t stretch much with weight. Use static ropes for rappelling, caving, canyoning and similar.
Dynamic ropes refer to the amount of force transmitted to a climber during a fall.
A rope with a low maximum impact force absorbs more of the energy generated in a fall over a longer period of time, transmitting less to the climber and the protection system. This kind is suitable for climbing, where free falls may occur. The core is the main load-bearing element of the rope. The sheath is braided tightly around the outside of the core to protect it against abrasion. The core may be made by a twisted core ropes consisting of nylon yarn twisted into cordlets, which are then twisted into strands running the length of the rope.
