Breaking the Physical Limits of Lightgweighting

A common belief in bicycle wheel technology is being re-examined: weight is not always the determining factor for speed. In reality:

  • During climbs: Weight directly affects climbing efficiency; every 100 grams saved is significant.
  • On flat roads: Aerodynamic drag dominates; weight has minimal impact.
  • Power output: Regardless of terrain, higher power output is always fundamental to speed.

This is precisely the starting point for our fundamental rethinking of wheel design philosophy.

The Weight Revolution in Carbon Fiber Rims

Modern materials science has pushed carbon fiber rims to their extremes:

The use of T1000 carbon fiber has reduced the weight of a 50mm-deep rim to around 330 grams.

This figure is approaching the theoretical limit of current production technology.

However, pure weight reduction has introduced a new challenge: compromised structural stiffness.

The Cost of Lightweighting: The Lateral Stiffness Problem

When carbon fiber usage is minimized to the extreme, rim lateral stiffness can be affected:

  • The rim may deform during hard accelerations.
  • Cornering precision may decrease.
  • Heavier riders may experience noticeable "flex."

The traditional solution often involves adding more material, which contradicts the goal of lightweighting.

Our Answer: The Flucircle Bionic Structural Design

We found inspiration in the mechanical principles of nature:

Design Philosophy: The Lesson from Paper

A flat sheet of paper bends easily, but when folded into a corrugated structure:

Weight is barely increased.

Lateral stiffness improves exponentially.

It can support objects far exceeding its own weight.


The Core of Flucircle Technology

We applied this principle to the sidewall design of the rim:

  • Bionic Corrugated Structure: Introducing precisely calculated corrugations in key stress areas of the rim.
  • Localized Reinforcement: Strengthening the structure only where stiffness is needed.
  • Weight Optimization: Avoiding thickening across the entire area, maintaining extreme lightweight.

Performance Breakthrough

Compared to traditional designs, Flucircle technology achieves:

  • 35% increase in lateral stiffness, rivaling heavyweight race wheels.
  • Only 2-3% increase in weight, maintaining top-tier lightweight status.
  • Aerodynamic optimization: The corrugated structure also improves airflow attachment.

Reduced fatigue accumulation, suitable for endurance rides and races.

Technical Specification Comparison


Future Outlook

Flucircle technology is just the beginning of our rethinking of wheel design:

Developing customized corrugation patterns for different rim depths.

Exploring synergies with different carbon fiber layup directions.

Researching dynamically variable structures that adapt to different riding conditions.

Conclusion: Redefining What's Possible

In bicycle engineering, true innovation often comes from challenging established assumptions. Flucircle technology proves that lightweighting and stiffness are not a zero-sum game. Through intelligent structural design rather than simple material addition, we have opened a new performance dimension for carbon fiber wheelsets.

This is not just about a lighter, stiffer rim; it is a redefinition of the boundaries of bicycle performance. The difference may be almost invisible on the weight scale, but in every pedal stroke, in every corner, you will feel a fundamental difference.

Technical Statement: The Flucircle design is protected by multiple international patents. All data is based on independent third-party laboratory test results. Actual experience may vary depending on specific riding conditions and individual perception.
