Rim Roundness Test
Tolerance: 卤0.2mm
Rim Roundness Test
Measures rim roundness and flatness to ensure consistent geometry.
Before any DRACO rim reaches production, it passes through a comprehensive testing protocol. We test prototypes. We test production samples. We test until we're confident it will perform beyond expectations.
