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:

  1. Stability : Its density provides excellent stability at high speed.
  2. Durability : Very resistant, maple ensures a long life for the ski.
  3. Responsiveness : It offers rapid energy return, ideal for aggressive skiers.
  4. 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:

  1. Lightness : Ideal for more manageable and less tiring skis.
  2. Flexibility : Offers a softer flex, suitable for intermediate skiers.
  3. Vibration Absorption : Provides greater comfort by absorbing shocks.
  4. 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.
