EXS Airank Seatpost

Taking a seatpost, from the testing machine clamp to the saddle rail, the exposed length will be 250mm
The machine applies force at a point 60mm behind the center of the seat clamp.
A downward force of 75kg is applied.
The test is designed to simulate the real-world deflection of the seatpost under actual riding conditions.
 

The testing results show that the offset design does affect the comfort.
A bigger offset design offers better comfort in the seatpost.
In most daily riding conditions, the actual tube deformation is less than the testing data.
