Every unit is factory calibrated and inspected before dispatch; parameters on this page reflect shipped goods.
Wheel-end dynamometer rigs use the WST503 as the radial load element to characterise suspension, brake and cornering performance at the hub.
Radial load only
Replace a tension / compression spoke on bicycle, motorcycle and powersports wheels with the WST503 for live wheel-load data without instrumentation legs.
Spoke-fit form
Laboratory chassis dynos and road-load simulators pair two or more WST503 units to reconstruct real-world vertical and lateral wheel loads.
