Why is it important to place your hands under the curve during a biomechanical evaluation for the road bicycle?
The cyclist’s position on his own bicycle is unique and incomparable with that of other people. This is due to the fact that the optimal position is the result of a set of morphological, functional and postural factors which determine the result.
However, it is equally important to analyse the subject in the most appropriate position so that the result is as reliable as possible. Even though the majority of the amateur cyclists prefers to lean on the brake levers for a greater comfort, it is good to know that this position cannot be considered as a reference posture for the biomechanical analysis. This wrong belief probably derived from an habits’ analysis and not from an analytical study of the reference indices.
In fact, it is sufficient to reflect to understand that the analysis performed with the hands over the brake levers completely excludes the effect produced by the type of handlebar. In this case, whether you use a compact or a round handlebar, the cyclist’s position does not change.
It is also important to remember the scientific level of the comparison index: there are not scientific data that allow to compare the optimal position of the cyclist with the hands on the brake levers.
Instead, there are studies which show the correct position of your hands on the handlebar curve.
