Aerobar Setup: Does Lower Always Equal Faster?

Many athletes assume that the lower the aerobar, the faster the rider. This supposed dogma is wrong. Here’s why.

You still have to generate power

Lowering the aerobars shrinks the angle between the rider’s torso and thigh. Closing this angle too much creates biomechanical and metabolic limitations that can compromise both power and aerodynamics. One of these problems is hip flexor impingement. The hip flexor muscles pull the femur up toward the pelvis, and when the hip angle gets too small, these muscles can no longer pull effectively.
