Rim Fatigue

Tests the fatigue life of a wheel under bumpy conditions.

A wheel and tire (inflated to 120psi) are spun at 40kph by a rotating cylinder with 5mm raised “blocks” placed every 400mm. A standard load, 60kg front and 90kg rear, is placed on the wheel and kept constant throughout the test. The cylinder continues to spin and jar the wheel until failure.  To pass this test, a wheel should have no visible damage to the rim or hardware, or air loss due to leakage from the bead after.

This simulates real-life riding conditions and ensures quality rim construction and build.
