Introduction:
Skiing enthusiasts often find themselves at the crossroads of choosing the perfect edge sharpening angles for their skis. The decision often hinges on the intended use of the skis, whether it’s racing on the piste or venturing into the varied terrains of all-mountain skiing. In this article, we will delve into a comparison between race-grade 87° and all-mountain 89° edge sharpening angles to help you make an informed choice.
Race-Grade 87° Edge Sharpening:
Race-grade skis are designed for speed and precision, requiring a sharp edge that provides optimal grip and control on hardpack snow. The 87° edge angle is the standard for race skis for several reasons:
1. Enhanced Edge Hold: The steeper 87° angle increases the edge hold on the ski, making it more effective for high-speed turns on icy slopes.
2. Reduced Edge Drag: The sharp edge reduces the drag on the ski, allowing for faster speeds and better acceleration.
3. Improved Edge Engagement: The steeper angle makes the ski more responsive to edge engagement, which is crucial for maintaining control during turns.
4. Increased Edge Life: With the 87° angle, the edge retains its sharpness for longer, reducing the need for frequent resharpening.
All-Mountain 89° Edge Sharpening:
All-mountain skis are designed for versatility, catering to skiers who enjoy a mix of groomed trails, off-piste, and park skiing. The 89° edge angle offers several benefits for this versatile category:
1. Improved Edge Hold on Variable Terrain: The slightly wider edge angle provides better edge hold on variable terrain, including soft snow and ice.
2. Reduced Edge Drag: Similar to the 87° angle, the 89° angle reduces edge drag, allowing for better speed and maneuverability.
3. Increased Edge Engagement: The wider angle makes the ski more forgiving on less-than-ideal snow conditions, ensuring better edge engagement even when the conditions are less than perfect.
4. Longer Edge Life: The 89° angle allows the edge to remain sharp for a longer period, reducing the frequency of resharpening.
Comparison:
While both the 87° and 89° edge angles offer their respective advantages, the main differences lie in the intended use of the skis:
– Race-grade 87°: Ideal for skiers who focus on speed and precision on hardpack snow, such as icy pistes. The steeper angle offers maximum edge hold, control, and edge life.
– All-mountain 89°: Suitable for skiers who enjoy a variety of terrain, including groomed trails, off-piste, and park skiing. The slightly wider angle provides improved edge hold on variable terrain, while still maintaining good speed and maneuverability.
Conclusion:
Choosing the right edge sharpening angle for your skis depends on your skiing style and preferences. Race-grade 87° edges are perfect for skiers who prioritize speed and precision on hardpack snow, while all-mountain 89° edges offer versatility and improved edge hold on a variety of terrains. Ultimately, the decision should align with your personal skiing goals and the type of snow conditions you encounter most frequently.
