4Za wheels undergo severe dynamic machine testing. The wheels are driven by a chain in order to create the same type of stress on the spokes and hubs while actually riding the wheel.
The big contact drum under the wheel simulates various roads conditions. Going from smooth to bad, bumpy roads. Footage shows we attribute great value to the impact resistance of our wheels Angular movement of the wheel simulates the load applied on the wheel when concerning while applying power on the pedals.
Once the test is completed we accurately verify spoke tension and check for any surface crack in the rim or hub flanges.
