How to Choose Foot & Knee Ascenders
Foot and knee ascenders are a big help in making the climbing of the rope easier and more efficient. However, with all the options available, there are certain factors that you need to consider to allow you to buy the right product.
The first thing that you need to consider when buying a knee or foot ascender is its construction quality. You need to know how this product looks in terms of its physical appearance. Does it look durable? What are the materials used in manufacturing the product?
I suggest looking for durable and tough materials such as stainless steel, aluminum, and other similar materials. You also need to look for polyester and nylon in terms of the straps and the other parts of the product. The goal is to put a premium on quality when choosing the knee or foot ascender.
Another factor to consider is the weight of the ascender. Choosing the lightest ascender is a good decision since it can also help in making your climb so much easier. I have used the lightest ascenders so many times in the past. Some of them will not be felt during the climb because of their lightness.
Another factor that you can consider is the design of the ascenders. And I prefer it compact. The smaller the ascender is, the better for you because it is much easier to use compared to the large one. The lightness and the compact design are related to each other in terms of providing the climber with an easier way to climb.
Another factor to consider is how the ascender makes adjustments in relation to the physical feature of the user. Look for a foot or knee ascender that is easy to adjust because that will help your climb much easier. Climbers have different body structures, heights, and weights, but with an easy-adjustment ascender, they can easily adjust to the proportion of your body.
Other Features to Consider
Choosing between Left or Right Foot Ascender
Many climbers always ask where to choose between left and right foot ascenders. The easiest way to figure it out is to know which is your power leg or dominant leg. If you do not know it, there is a way to determine your dominant leg.
All you have to do is determine which leg is on the ground when you run and then jump. The foot that is on the ground when you jump is your dominant leg. If it is the left leg, you will use the left foot ascender and a knee ascender on the other leg.
The best foot & knee ascender are essential for a smooth and quick climb. However, choosing the most suitable ascender for your needs requires a lot of research to maximize its full usage.
