Invisible Structural Damage: Unlike metal frames that bend or dent, carbon fiber composites absorb impacts through internal ply separation (delamination) that may leave the outer surface visually unscathed.

Master the Tap Test: Gently tap suspect areas with a coin; a sharp, high-pitched ping indicates solid laminate, whereas a dull, hollow thud signals internal voiding or delamination.

Mandatory Fork Replacement: Front-end or head-on impacts require automatic replacement of the carbon fork; steerer tube stress inside the headset cannot be evaluated visually or via tap testing.

Inspect Carbon Wheelsets: Always spin wheelsets after a crash to check for rim lateral runout, radial flat spots, spoke tension drop, and delamination along the brake track or sidewall.

Respect Testing Boundaries: High internal manufacturing standards (such as 120J impact testing, an internal standard at 3× the UCI minimum) prove initial strength, but offer no guarantee after real-world impact damage.
