Available Options
Feature:
1. Reducing Inertial Imbalance
The wavy design alters the mass distribution of the wheel, bringing its center of mass closer to the geometric center during rotation. This adjustment helps evenly distribute the centrifugal force, reducing vibrations caused by mass displacement and improving dynamic balance.
2. Enhancing Vibration Absorption
The wavy structure inherently offers some flexibility and elasticity, which can absorb vibrations and energy generated by road impacts or tire deformation during rotation. This improves ride smoothness.
3. Minimizing Variations in Air Resistance
The wavy design can create a smoother airflow distribution, reducing air turbulence during high-speed rotation. This helps avoid additional torque caused by uneven airflow, thereby stabilizing the wheel.
4. Distributing Stress and Reducing Resonance
The wavy shape promotes more even stress distribution, preventing stress concentration. Additionally, it can alter the wheel's resonance frequency, reducing imbalances caused by resonance effects.

Note:
We provide custom assembly wheels building service because have many configurations, so the weight of the wheels need be calculated.
If you need lightweight wheels, please choose lightweight rims, hubs, and spokes.
