The main body is made of nylon PA material, which has strong fatigue resistance, and the overall service life is several times that of ABS material.
Use 75A soldness material. Softer material let the wheels quieter and make less noise while pushing.
The 6061T6 aluminum alloy shaft at the key shaft part has an overall lifespan that is 3-5 times longer than that of nylon shafts (yield strength and tensile strength are 3-5 times that of nylon materials.)
Noise reduction: Improved sound insulation: These wheels are designed to reduce noise and minimize noise on smooth floors for a ride.
Design: Omni-directional:The omni-directional design ensures smooth steering in any direction and enhances Brompton's versatility.
