gripSPEEDER Inline Skate: What the 2018 Concept Tried to Do
The gripSPEEDER inline skate appeared in 2018 as an unconventional five-wheel speed-skate concept. Contemporary promotional material described two large outer wheels on flexible titanium forks and three smaller central wheels intended to contact the road under particular loads. The idea was visually memorable, but promotional claims are not the same as independent performance evidence.
Quick answer: the gripSPEEDER is best treated as a design case study. Its mechanism proposed changing which wheels carried the load during gliding, pushing and cornering. To know whether that improved speed or control, a reviewer would need repeatable comparison tests, dimensional data and evidence about durability.
How the five-wheel mechanism was described
The 2018 description said the two 110 mm outer wheels supported the skate during the glide phase while three smaller “grip” wheels sat slightly above the surface. Under push-off or cornering load, the flexible structure was intended to let the smaller wheels contact the ground.
That is an engineering hypothesis: fewer rolling contacts during the glide, then additional contact when the skater loads an edge. It does not automatically prove lower resistance, higher grip or better power transfer. Wheel compound, deformation, alignment, frame stiffness, surface texture and technique all affect the outcome.
Why two-wheel support needs careful testing
A long distance between the front and rear contact points can track differently from a conventional three- or four-wheel frame. It may bridge some surface features while responding differently to short bumps, cracks and rapid direction changes. The relevant question is not whether two wheels are always better or worse; it is how the complete loaded system behaves across representative surfaces.
Testing should record speed, acceleration, stopping, cornering, vibration and repeatability. Skaters should not infer safety from a promotional animation or isolated run.
Flexible parts create both opportunities and trade-offs
A flexible element can store and release energy, isolate vibration or alter contact. It can also introduce movement, fatigue and maintenance requirements. Engineers would need to measure deflection under load, energy loss, return consistency, alignment after repeated cycles and what happens if a fork or wheel is damaged.
The same logic applies to any unusual skate frame. A novel mechanism deserves a test plan that can reveal failure as well as success.
Would the design fit current race rules?
World Skate’s 2025 speed rulebook allows a maximum of five inline wheels, limits skate length to 50 centimetres and sets a 110 mm maximum wheel diameter for most events, with 125 mm permitted for the marathon. A particular gripSPEEDER configuration would still need its exact dimensions and equipment details checked against the current rules for the event.
Rules are only one test. An allowed design is not automatically faster, durable or suitable for a particular skater.
How to evaluate an unconventional inline skate
- Measure wheel diameters, frame length, mount spacing and ride height.
- Document which wheels contact the ground under defined loads.
- Use the same skater, course, weather and timing method for comparisons.
- Repeat runs and change test order to reduce learning and fatigue effects.
- Inspect flexible parts, axles and alignment before and after testing.
- Report unsuccessful runs and uncertainty, not only the best result.

What happened to the gripSPEEDER?
Public promotional coverage established that the concept existed in 2018, but that alone does not document production volume, independent test results or its later commercial status. Without reliable company records, it would be speculation to declare one reason the design did or did not become common.
A useful experiment, judged by evidence
The gripSPEEDER inline skate remains interesting because it challenged the fixed, evenly loaded frame. The fair conclusion is neither praise nor dismissal: describe the mechanism accurately, identify the trade-offs and require repeatable evidence before turning a design claim into a performance claim.
