Ski-Mojo Blue, Silver or Gold: Which to Choose According to Your Weight?
Blue, Silver or Gold: how to choose the right Ski-Mojo spring for your weight and your practice? Complete guide with comparison table.
Introduction: the right spring makes all the difference
You have decided to invest in a Ski-Mojo Original Performance. Excellent decision. But faced with the three spring versions available — Blue, Silver and Gold — many prospective buyers get stuck. Which to choose? Is it only a question of weight? Of skiing level? Of type of pain?
This guide answers all these questions precisely, so that you arrive on the slopes with the right setting from day one.
Chapter 1: understanding the principle of Ski-Mojo springs
How does the spring work?
The Ski-Mojo uses a central coil spring that absorbs energy when the knee flexes and returns it on extension. This simple mechanism offloads the quadriceps and joints significantly — up to 30% of body weight according to the brand's internal studies.
The spring's stiffness directly determines the intensity of the assistance. A spring that is too soft will not support a heavy skier enough. A spring that is too stiff will hinder a light skier's movements and make flexion uncomfortable.
Why three colors?
Ski-Mojo has standardized its offer around three stiffness levels, color-coded for quick identification. This system also lets you change the springs at home if your weight changes or if you want to test a different level.
Chapter 2: the Blue spring — for light skiers
Target profile
The Blue spring is the softest of the three. It is recommended for skiers whose weight is between 50 and 70 kg. It is often the choice of women, teenagers or people of small build.
Feel on the slopes
With the Blue, the assistance is noticeable but natural. You feel a slight “boost” on each extension without feeling that the mechanism is “working in your place”. Flexion stays fluid and proprioception — that feeling of contact with the snow — is perfectly preserved.
When to choose the Blue?
Your weight is under 70 kg
You ski technically and are looking for light joint protection
You are in a return phase after a minor injury and want progressive support
Chapter 3: the Silver spring — the choice of most people
Target profile
The Silver is the standard spring, the one Ski-Mojo recommends first if you have no particular constraint. It suits skiers weighing between 70 and 90 kg.
Feel on the slopes
With the Silver, the assistance is clearly felt. The quadriceps recover faster between runs, and people with mild to moderate osteoarthritis report a significant reduction in pain from the first day. It is the most versatile spring: piste skiing, Nordic ski touring, big elevation gain.
When to choose the Silver?
Your weight is between 70 and 90 kg
You are looking for a good balance between assistance and freedom of movement
You are starting out with the Ski-Mojo and want a “universal” setting
Chapter 4: the Gold spring — for heavy or demanding skiers
Target profile
The Gold is the stiffest spring. It is designed for skiers weighing 90 kg and more, but also for intensive skiers who string together many consecutive days on demanding terrain (off-piste, moguls, veteran competition skiing).
Feel on the slopes
The assistance is powerful and immediately noticeable. Gold users often describe a feeling of “legs that no longer tire”. In return, flexion requires slightly more effort, and an adaptation phase of 1 to 2 days is often needed.
When to choose the Gold?
Your weight exceeds 90 kg
You suffer from severe osteoarthritis or have a knee replacement
You ski more than 10 days a year and want maximum protection
Chapter 5: summary comparison table
| Color | Recommended weight | Assistance | Ideal profile |
|---|---|---|---|
| Blue | 50 – 70 kg | Light and natural | Light skier, return after injury |
| Silver | 70 – 90 kg | Balanced and versatile | Standard use, mild osteoarthritis |
| Gold | 90 kg and + | Powerful and maximal | Heavy skier, severe osteoarthritis, intensive practice |
Conclusion: trust the weight, fine-tune with the feel
The golden rule: start with the spring matching your weight bracket. If you are at the upper end of a bracket (e.g. 88 kg), go up one notch. The springs are interchangeable, so nothing is final.
