The choice of wood for the core of an alpine ski plays a crucial role in its performance and characteristics. Maple and poplar are two commonly used species, each bringing its own qualities to the construction of the ski.
Maple core
Maple is a hard, dense and durable wood, offering the following benefits:
- Stability : Its density provides excellent stability at high speed.
- Durability : Very resistant, maple ensures a long life for the ski.
- Responsiveness : It offers rapid energy return, ideal for aggressive skiers.
- Edge hold : Its rigidity promotes better edge hold.
However, maple has some drawbacks:
- Heavier, which may affect handling for some skiers.
- Less absorption of vibrations, which can make the ski more “nervous”.
Poplar core
Poplar is a softer and lighter wood, with the following characteristics:
- Lightness : Ideal for more manageable and less tiring skis.
- Flexibility : Offers a softer flex, suitable for intermediate skiers.
- Vibration Absorption : Provides greater comfort by absorbing shocks.
- Versatility : Suitable for a wide range of skiing styles.
Disadvantages of poplar include:
- Less stability at high speeds than maple.
- Less durability, especially with heavy use.
Conclusion
The choice between maple and poplar depends on the skiing style and the skier's preferences:
- Maple is suitable for aggressive skiers looking for performance and stability.
- Poplar is ideal for intermediate skiers or those who prioritize comfort and versatility.
Many manufacturers opt for a mix of these two woods, combining their advantages to create versatile and high-performance skis.
