Well, the bushing durometer refers to the hardness of the rubber bushings that sit between the skateboard deck and the trucks. It plays a significant role in determining how the trucks respond to your movements and, ultimately, your ride. In this article, we’ll dive into the fascinating world of bushing durometer and explore why it is essential for every skateboarder to understand its importance.
What is bushing durometer?
Definition of bushing durometer
Bushing durometer refers to the measurement of the hardness of the bushings used in skateboard trucks. Durometer is a unit of measurement that quantifies the hardness of a material, specifically elastomers such as rubber. In the case of skateboard trucks, the bushing durometer determines how easily the trucks can turn and how much resistance they provide when executing tricks or maneuvers.
Measurement of bushing durometer
Bushing durometer is measured using a device called a durometer tester. This handheld instrument features a blunt, needle-like tip that is pressed against the surface of the bushing. The measurement is displayed on a dial or digital screen and is typically given as a numerical value followed by the letter “A” or “B”, which represents different durometer scales.
Understanding skateboard trucks
Overview of skateboard trucks
Skateboard trucks are the metal components that attach the wheels to the skateboard deck, allowing it to pivot and turn. They consist of various parts, including the baseplate, hanger, axle, kingpin, and bushings. Trucks play a crucial role in a skateboard’s maneuverability and stability.
Components of skateboard trucks
Skateboard trucks comprise several key components. The baseplate is the part that is mounted on the skateboard deck, providing stability and a foundation for the rest of the truck. The hanger is the T-shaped portion that holds the axle and wheels. The axle is the metal rod that the wheels are mounted on, and the kingpin is the bolt that holds the hanger and baseplate together. Lastly, the bushings are the small, cylindrical cushions made of rubber or urethane that are inserted between the hanger and baseplate. These bushings determine the turning and responsiveness of the skateboard.
The role of bushings in skateboard trucks
Bushing durometer plays a vital role in the performance of skateboard trucks. The bushings act as a cushion between the hanger and the baseplate, providing resistance and allowing the skateboard to turn smoothly. The durometer rating of the bushings affects how easily the trucks can turn and how much resistance they provide. Softer bushings allow for easier turning, while harder bushings offer more stability and resistance to turning. The choice of bushing durometer greatly impacts the overall feel and responsiveness of the skateboard.
Exploring the concept of durometer
Definition of durometer
Durometer is a measurement of the hardness of a material, particularly elastomers such as rubber or urethane. It determines the material’s resistance to indentation or penetration by a blunt tip. The higher the durometer reading, the harder the material.
Different types of durometer scales
There are different durometer scales used to measure the hardness of various materials. The most commonly used scale in skateboarding is the Shore durometer scale. The Shore A scale measures the hardness of flexible materials, while the Shore D scale is used for harder materials. In the context of skateboard bushings, the Shore A scale is typically used, and the durometer is indicated by a numerical value followed by the letter “A”.
Impact of bushing durometer on skateboard performance
Effect of soft bushings
Using softer bushings with a lower durometer rating provides increased maneuverability and makes turning easier. Soft bushings compress more easily, allowing for smoother and more fluid turns. This can be ideal for technical skateboarding styles that require quick and sharp turns, such as street skating or technical tricks. However, softer bushings may sacrifice stability at higher speeds and may lead to a “squirrely” or unstable feel when riding at faster velocities.
Effect of hard bushings
Harder bushings with a higher durometer rating offer greater stability and resistance to turning. They provide a more controlled and stable ride, making them suitable for higher speeds and downhill skateboarding. The increased resistance in turning can also be advantageous for skateboarding styles that require more stability and precision, such as bowl or vert skating. However, hard bushings may require more effort and force to turn, reducing maneuverability and responsiveness.
Optimal bushing durometer for different riding styles
The choice of bushing durometer ultimately depends on individual preferences and riding styles. For street and technical skateboarding, where quick turns and responsiveness are crucial, softer bushings with a durometer rating in the 80A to 90A range may be preferred. For downhill or higher-speed riding, harder bushings in the 90A to 100A range or even higher may offer greater stability and control. It is important to experiment and find the durometer that suits your specific style and needs.
Factors influencing bushing durometer selection
Rider’s weight
The weight of the skateboarder can significantly influence the selection of bushing durometer. Generally, heavier riders may benefit from using harder bushings to accommodate the weight and provide optimal stability. Lighter riders, on the other hand, might find softer bushings more suitable as they require less force to initiate turns.
Riding style and preferences
Different skateboarding styles and personal preferences also play a crucial role in determining the ideal bushing durometer. Riders who prioritize quick and sharp turns might prefer softer bushings, while those seeking greater stability and control may lean towards harder bushings. It is essential to consider the specific demands of your riding style and the feel you want to achieve on your skateboard.
Skateboard deck and truck setup
The choice of bushing durometer can be influenced by your skateboard deck and truck setup. Factors such as the width and length of the deck, as well as the type of trucks used, can impact the performance and responsiveness of the bushings. Experimentation with different setups and seeking advice from experienced skateboarders can help you find the optimal combination of components and bushing durometer for your specific setup.
Choosing the right bushing durometer
Determining the preferred durometer
Choosing the right bushing durometer involves determining your preferred level of responsiveness and stability based on your riding style, weight, and personal preferences. It is helpful to try out different bushings with varying durometer ratings to gauge how they affect your skateboard’s performance and feel.
Experimentation and personal preference
Finding the perfect bushing durometer often requires experimentation and trial and error. It is important to keep an open mind and be willing to make adjustments to your setup until you find the durometer that suits your needs. Personal preference plays a significant role, as what works for one rider may not work for another. Take the time to try out different setups, borrow bushings from friends, or invest in a bushing variety pack to test out various durometers.
