Everything about wheel cores
Short answer:
Wheel cores are a crucial part of inline skate wheels, providing the structure needed for optimal performance. While most modern ones are made of plastic, newer options, including metal cores, have entered the market, offering different benefits depending on your skating style.
What are wheel cores and why do they matter?
When it comes to inline skating, they play a significant role in how your wheels perform. The core is the central part of the wheel that holds the bearings, which in turn, enable the wheel to roll. Without a sturdy core, the wheel would be too soft and unstable to provide a smooth ride.
Modern inline skate wheel cores are typically made from plastic, but in recent years, metal cores have become more popular, especially among high-performance skaters. These metal cores offer increased stiffness, allowing for better speed and control. For example, aluminum cores are now used in some wheels, such as the ones produced by Farmers, a brand known for introducing metal cores to the inline skating world.
The evolution of wheel cores
They have evolved over time. While today's inline skates mostly feature plastic cores, early skates from the 19th century often had metal or even clay wheels. However, modern plastic cores have proven to be the best option for most skaters due to their balance of performance and affordability.
A major development in recent years has been the introduction of metal wheel cores. Brands like Famus have led the way by offering aluminum cores that increase speed and durability. Although metal cores are slightly heavier than plastic, many skaters find the trade-off worth it for the performance boost.
Core shapes and materials
The shape and material of your wheel core can significantly impact your skating experience. Larger cores offer increased speed but reduce the amount of urethane on the wheel, meaning there’s less material to wear down over time. Smaller cores provide more urethane for durability but may not roll as fast.
Additionally, they can feature different shapes, such as flat or with teeth that grip the urethane. These designs help secure the urethane and improve the wheel's overall stability. While core design is essential, material choice also plays a crucial role. Plastic cores are common for most inline skaters, while aluminum cores offer an upgrade for those seeking higher performance.
Wheel cores determine strength and performance, but don't overlook how the frame material and spacers work together to ensure that your wheels spin smoothly and efficiently.
Are metal cores good for street skating?
There’s ongoing debate about whether metal cores are suitable for street skating. While metal cores provide excellent speed and stability, they can be more fragile than plastic when exposed to rough surfaces and heavy impacts. However, most skaters find them durable enough for various skating styles, including street skating, as long as they're used with care.
3-Spoke vs. 6-Spoke wheel cores
Another variation among them is the number of spokes. Some wheels have a 3-spoke design, while others feature 6 spokes. While the difference is mostly aesthetic, both designs offer similar performance in terms of strength and weight. Ultimately, the choice comes down to personal preference and style.
How to install bearings in wheels with metal cores
Installing bearings in wheels with metal cores can be tricky due to the increased stiffness of the core. To make the process easier, we recommend using a special bearing pusher tool designed for this purpose. For removal, using a cylindrical bearing spacer allows you to dislodge the bearing more easily by providing a bit of leverage.
Conclusion
Whether you’re a casual skater or a high-performance enthusiast, understanding wheel cores can help you make better decisions when choosing your wheels. Metal cores offer speed and stability, while plastic cores are more forgiving and versatile for everyday skating. To find the best ones for your skates, explore our wide selection at off wheels.
