Choosing The Right Frames For Yourself!

Choosing the Right Frame: Carbon vs. Aluminium for Inline Speed Skating

In high-performance speed skating, every bit of energy counts. Your frame is the bridge between your boots and the ground, channelling power with every stride. And when you’re chasing fractions of a second, the material and design of your frame can be the difference between a podium finish and falling short.

This guide compares carbon vs. aluminium inline skate frames, as well as different frames lengths, helping you choose the best fit for your race style, technical needs, and long-term goals.

Why Frame Material Impacts Speed

Your frame affects three core areas of skating performance:

  • Power transfer – How efficiently your effort reaches the wheels.

  • Rigidity – How well the frame resists flex during lateral pressure.

  • Vibration control – How much surface feedback is absorbed by your legs.

Stiffer, lighter frames allow advanced skaters to push harder, corner tighter, and recover faster at speed.

Carbon Frames: Lightweight, Responsive, and Race-Tuned

The Supercell Bont frame is Bont’s most advanced inline frame, built from high-strength carbon fibre with a honeycomb core for unmatched stiffness and weight savings.

Key advantages:

  • Maximum stiffness for direct power delivery.

  • Feather-light design for faster acceleration and reduced fatigue.

  • Exceptional vibration dampening ideal for marathons and road racing.

Best for:

  • Sprint and long-distance racing.

  • Elite skaters seeking the lightest, most responsive ride.

  • Track and road surfaces that reward precision and speed.

Aluminium Frames: Durable, Forgiving, and Ideal for Development

Aluminium frames remain a popular option for skaters refining their technique. While heavier than carbon, they provide a stable, forgiving platform for training and progression.

Performance features:

  • More flex underfoot for stride feedback and skill development.

  • Durable construction for everyday use on varied terrain.

  • More affordable for skaters building their first performance setup.

 

Understanding Frame Lengths: The Unsung Hero of Performance

Beyond the material, the length of your frame (often referred to as the wheelbase) plays a critical role in how your skates perform. It directly impacts stability, manoeuvrability, and how efficiently you can maintain speed. Frame lengths typically vary, accommodating different wheel configurations (e.g., 3x110mm, 4x100mm, 3x125mm).

How Frame Length Impacts Inline Skating:

1. For Kids (Young Skaters):

  • Shorter Frames (e.g., 3x90mm, 4x84mm or 4x90mm for smaller feet): For younger or less experienced skaters, a slightly shorter frame is often preferred. It offers greater manoeuvrability and control, which is crucial for learning technique, navigating tighter spaces on track, and building confidence. A lower centre of gravity with smaller wheels can also aid stability. While not as fast at top end, they allow quicker acceleration and easier turning.

  • Progression: As a child grows and their technique develops, they will naturally progress to longer frames and larger wheels 4x100mm or 4x110mm  . It’s important not to rush this, ensuring they master control and fundamental skills on a more forgiving setup first.

2. For Adults:

  • Versatility: Adult skaters have a wider range of options depending on their discipline, foot size, and preference. Generally, taller or heavier adults might opt for slightly longer frames for enhanced stability.

  • Foot Size Consideration: Ideally, frame length should be proportionate to the skater's boot size. A frame that's too short for a large foot can compromise stability, while one too long for a small foot can hinder manoeuvrability and make it difficult to achieve proper technique.

3. On a Skating Track (Indoor/ Sprints):

  • Shorter to Medium Length Frames (e.g., 3x110mm, 3x100mm+1x90mm HiLo, 4x110mm or slightly shorter variations): On indoor or outdoor tracks with tight curves, manoeuvrability is key. Shorter frames allow for a smaller turning radius, enabling skaters to take corners more efficiently and maintain speed through bends. While top speed might be marginally lower on the straights compared to very long frames, the ability to navigate corners swiftly often outweighs this.

  • Acceleration: Sprint races require explosive acceleration, and shorter frames with fewer, larger wheels (e.g., 3x110mm) can sometimes offer a quicker initial burst due to less rolling resistance and better power transfer in the initial push.

4. On a Road Circuit:

  • Medium to Longer Frames (e.g., 3x110mm, 4x110mm,or 3x125mm): Road circuits often feature longer straights and wider, sweeping turns compared to a track. Here, stability at high speeds and efficiencyover longer distances become more critical. Longer frames provide greater stability, reducing "speed wobble" and allowing for a more consistent, powerful stride.

  • Speed Maintenance: The slightly increased length aids in maintaining momentum and top speed over varied terrain and longer stretches, which is advantageous on road courses.

5. In a Marathon:

  • Longer Frames (e.g., 3x125mm, 4x110mm for those who prefer 4 wheels): Marathons are the ultimate test of endurance, where efficiency, stability, and sustained high speed are paramount. Longer frames, particularly those accommodating 125mm wheels (in a 3-wheel setup), are now the standard for marathon racing.

  • Reduced Effort: Larger wheels mean fewer rotations per kilometre, leading to less energy expenditure over long distances. The longer wheelbase provides maximum stability, crucial for hours of continuous skating and managing fatigue. While initial acceleration is slower, the ability to maintain speed with less effort makes them superior for distance events.

 

How to Choose Based on Your Skater Profile

 

Factor Best Option Reason
Sprint power Carbon frame Stiffness supports explosive push-off and acceleration.
Budget-conscious Aluminium frame Affordable and easier to replace if damaged.
Long-distance control Both Choose based on comfort, terrain preference, and wheel size (longer frames for bigger wheels).
Technique development Aluminium frame Forgiving flex helps skaters refine movement and receive better feedback.
Lightweight performance Carbon frame Reduced fatigue over time with less mass and efficient power transfer.
Manoeuvrability Shorter Frame Essential for tight turns on track or urban agility.
Stability at Speed Longer Frame Crucial for high-speed road courses and marathons to prevent wobble.
Young/Developing Skater Shorter/Medium Aluminium Frame Provides control, stability, and allows focus on technique without excessive length.
Marathon/Road Skater Longer Carbon Frame Maximises efficiency, stability, and speed over long distances; reduces fatigue.
Track Sprinter Medium Carbon Frame Balances acceleration out of corners with straight-line speed.

 

Frame Matching: Get the Most from Your Setup

A frame is only as good as the components it works with. For the best performance, match your frame with gear that supports its strengths.

For example, the Supercell Carbon Frame:

  • Pair with the Vaypor Inline Bont for maximum energy transfer and custom fit.

  • Use Red Magic Hardcore Wheels 125mm /  Enigma 110mm to enhance grip and roll.

  • Add Bont Ceramic Bearings for long-lasting glide and reduced rolling resistance.

This elite configuration is trusted by skaters competing at the highest levels of international inline racing.

 

Conclusion: Build Around Your Goals

There’s no one-size-fits-all answer. The best frame is the one that fits your current goals and progression path. If you’re chasing podiums and want every watt to count, go carbon with an appropriate length for your discipline. If you’re building technique and want value and durability, aluminium is the way to go, often starting with a more manageable length. Remember, your perfect setup evolves as you do!
