Vertical Rigidity Test

Vertical Rigidity Test for LightCarbon Rims

The vertical rigidity test on bike rims is performed to determine the stiffness or rigidity of the rim, which is a key factor in the overall performance and handling of a bicycle. The stiffness of the rim can affect the responsiveness of the bike, the control and stability of the ride, and the transmission of power from the rider to the road.

A stiffer rim will generally provide a more responsive and direct feel, while a more flexible rim may provide a smoother and more comfortable ride. However, too much flex in the rim can also negatively impact handling and stability, as well as reduce the efficiency of power transfer.

By performing the vertical rigidity Test on bike rims, manufacturers and riders can obtain important information about the stiffness of the rim and make informed decisions about the best rims for a given riding style or performance goal. Additionally, the results of the test can be used to compare and evaluate different rim designs and materials, and to make improvements in the quality and performance of bike rims.

Below is an example case of vertical rigidity test on LightCarbon road rim RD25-38C :
