How to Test Vertical Impact on Carbon Bike Rim?

Tests the pressure at which a rim will fail due to vertical impact.

A weight is hung above a secured rim and dropped directly onto the top of the rim. Increasing weights are dropped until the impact meets UCI standard of 355.8 joules. A wheel passes if no damage occurs at this impact.

Simulates the impact on a wheel during a crash, or running into a curb at high speed.
