Binding 105-120 mm: guide for freerando

This guide helps you understand and choose a binding suitable for wide skis (105–120 mm at the waist). Technical information, comparisons between models D105 and D120, differences between versions 10 and 12, and tips for your freerando practice.

Technical characteristics of models D105 and D120

• Width compatibility: designed for skis with a waist around 105 to 120 mm. Ensure that the binding is compatible with your width and type of ski.
• DIN adjustment range: two common versions correspond to different max adjustments (10 and 12). The D105 model is generally optimized for lower adjustments and less weight; the D120 offers a higher DIN range and a more robust construction.
• Walk/downhill function: significant travel length for ascent, simple and secure conversion mechanism for descent.
• Weight and materials: D105 prioritizes lightness for ascent. D120 prioritizes strength and energy transmission for descent.
• Retention system: articulated heel piece with controlled rotation and shock absorption stops to limit unwanted releases during descent.

Advantages and specifics of versions 10 and 12

The so-called "10" and "12" versions correspond to the maximum DIN adjustment level and overall robustness.

• Version 10: lighter, sufficient for the majority of touring skiers and for moderate freerando uses. Ideal if you prioritize ascent and seek a good weight/security compromise.
• Version 12: intended for heavier or more aggressive skiers during descent. Offers better transmission and increased security at high speeds or on challenging terrain.

Applications and practice of freerando

Freerando combines technical hikes and off-piste descents. It requires bindings capable of walking efficiently and handling demanding descents. For this practice, prioritize:

• A binding with good travel in walk mode.
• A DIN adjustment suitable for your build and skiing style.
• Compatibility with wide brakes or integrated systems for skis >100 mm at the waist.

If you purchase the equipment in a pack, consider the binding and ski pack association to optimize mounting, adjustments, and compatibility.

How to choose a ski touring binding suitable for my level?

• Beginner/leisure: choose the lightest version with a moderate max DIN (e.g., 10). Prioritize ease of use and safety.
• Intermediate: opt for a model balanced between weight and strength. A sufficient DIN adjustment for your weight and progress is essential.
• Advanced/committed: prefer a more robust binding (e.g., version 12) offering better transmission and resistance during heavy descents.

Criteria to consider for purchase

• Weight: important if your outings involve a lot of ascent.
• DIN range: suitable for your weight, level, and skiing style.
• Sole compatibility: check that your boots and the binding are compatible (ISO/Tech standards or touring).
• Safety and performance in descent: robustness, anti-release system, and quality of friction.
• Ease of use: simplicity of switching between walk/descent and adjustments in the field.
• Budget: there are also economical options, for example, if you are looking for a cheap nordic touring binding for more relaxed outings.

FAQ

What are the differences between models D105 and D120?

D105 = prioritizes lightness and ascent. D120 = prioritizes downhill performance and higher DIN range. Choose according to your weight and intensity of practice.

How to choose a 110-125 mm binding?

To choose a 110-125 mm binding, check compatibility with the ski width, the appropriate brake, and choose the DIN range corresponding to your profile. Also consider weight and robustness according to your practice.

What criteria for mounting and maintenance?

Have the bindings mounted and adjusted by a professional. Regularly check the tightness, wear of parts, and proper functioning of the walk/descent mechanism.

Conclusion

For freerando on wide skis (105–120 mm at the waist), prioritize a binding balancing weight for ascent and strength for descent. Determine the version (10 or 12) according to your build and style. And if budget is a constraint, inquire about economical alternatives, or even a cheap nordic touring binding to start or for very light uses.
