You adjust cross-country skis, specifically the bindings, primarily to influence the balance between glide and grip.
The key adjustment involves moving the binding position. Moving the binding forward generally increases grip but decreases glide, while moving it backward increases glide but reduces grip. This adjustment allows you to fine-tune your skis' performance based on snow conditions and your skiing style.
Here's a breakdown:
-
Forward Adjustment: Shifting the binding forward places your weight more directly over the grip zone of the ski. This provides better contact for the grip section (often wax or fish scales) with the snow, improving traction and control, particularly on uphills. However, it reduces the length of the ski in front of the binding, which impacts the glide phase.
-
Backward Adjustment: Moving the binding backward shifts your weight slightly behind the grip zone. This allows more of the ski's surface to make contact with the snow during the glide phase, increasing speed and efficiency on flat or downhill terrain. However, it reduces pressure on the grip zone, potentially causing slipping, especially on uphills.
When to Adjust:
- Icy Conditions: Move the binding forward for more grip.
- Powdery Snow: Experiment with a backward or neutral position to maximize glide.
- Uphill Struggles: Move the binding forward.
- Excessive Slipping: Move the binding forward.
- Difficulty Gliding: Move the binding backward.
Specific Binding Systems:
Some cross-country ski bindings, such as Turnamic bindings, feature easily adjustable mechanisms that allow for on-the-fly adjustments without tools. Always consult the manufacturer's instructions for your specific binding system to ensure proper and safe adjustments.
