The Dynamic 3D Bike Fit

The 3D technology is fantastic and comes to add a lot in cycling. Currently, the same science available to the world’s great athletes, is available to all bike lovers.

The Dynamic 3D Bike Fit

In the last decades the bicycle industry has invested heavily in technologies that allow better performance of cyclists in general, from urban cyclists to high performance athletes.

Currently it is possible to purchase equipment made of carbon fiber, hydraulic brakes, air suspensions and”intelligent”(that adjust to the terrain automatically), electronic gear shift system, power meters, GPS-connected computer and so on. ..

The fact that such equipment has become popular in the market has allowed ordinary people to make more efficient use of bicycles, whether traveling longer distances or printing a higher average speed or the two together.

Within this technological evolution, many cyclists note that as important as having a good equipment, is to make sure that the bicycle is literally”adjusted”,”dressed” to your body in order to provide the best bike comfort, avoiding pain and injuries. Another important point is to make sure that the energy applied by the cyclist is being converted in displacement, without wasting of force and saving the movement.

Across the globe, athletes begin to modify the adjustments, distances and lengths of their bikes in search of the triad:”comfort, strength and efficiency.” Initially these modifications were made empirically through trial and error, based on the perception and sensitivity of the athlete. It was not long before the major sports research centers began their study work in analyzing the cyclist’s movement. There have been many protocols suggested through these surveys to adjust cyclists on the bike.

When the subject is Bike Fit, several centers have been known around the world: Serotta International Cycling Institute(SICI), Slowtwitch, Bike Fit, BikeFitting, Guru, Retül, GeoBiomized, Fit4Bike, among others.

Until then, evaluations were carried out statically. Surveys then direct to moving analysis through filming. But even when it was in motion, at the time of the analysis the video was paused to evaluate the position of the cyclist.

It was then that the incorporation of the computer science allowed the analysis of the cyclist during the pedaling in roller of indoor training. The cyclist pedals and through different methodologies, their angles of extension and flexion, as well as the distances between their anatomical points are measured.

We have no doubt that the great differential of this technology(3D) is the real-time evaluation of the dynamics of the position of the cyclist on the bike and in a three-dimensional way. In this way, the bike literally dresses itself to the body of the athlete.

One of the biggest mistakes is trying to fit the cyclist’s body to the bike. The Bike Fit is nothing more than the fit of the bike to the body of the cyclist, respecting their particularities.If the cyclist has an anthropometric, physiological / functional asymmetry, it should be referred to a specialist for treatment, being repositioned in the future.

Like any knowledge produced, the tendency is for this science to fall into common sense.Currently, these 3D systems are being marketed as a tool for Bike Fit associated with major bicycle manufacturers, and in some of them, the system operates in Wizard mode, allowing anyone to perform Bike Fit without requiring any specific knowledge of the professional , as if it were a smartphone application.

A good Bike Fit needs to be accompanied by a good anamnesis and a good physical evaluation, not only to fill out protocols, but also so that, with this information, the properly trained Bike Fitter can adjust the bike to the athlete’s body.

The big trend is that, as in some countries already, stores begin to acquire these equipment and offer these services to their customers as an added product. It turns out that the equipment by itself does not do any miracle. Just as a good tico-tico does not make anyone a good carpenter and neither does the acquisition of a Formula 1 will not make you a runner of the world circuit. Bike Fit 3D devices are only useful when operated, handled and interpreted by someone who is properly prepared for it. How to Identify a Good Bike Fit Service?

The first step is to identify if the Bike Fitter has training in the health area. Many people forget that the bike is being adjusted only as a way, to reposition the cyclist’s body. But in the end who suffers the consequences of the adjustment is the body of the cyclist. Only a health professional will have studied subjects such as anatomy, physiology, kinesiology, biomechanics, etc.

Another important point is to verify if this professional has professional registration to act as Bike Fitter. It is not uncommon to see the figure of the”bicycle fitter” related to someone who works in a bicycle workshop, or is / was a competitor, or store owner, or influential person in cycling. None of this is enough to work with Bike Fit. Not that these values ​​do not add to the professional, but training and technical / scientific knowledge are fundamental.

What has been worrying is that many protocols are created and aimed at people who do not even know the difference between a muscle and a ligament, have never studied at least one Cell Biology or even a Basic Cytology. They are stuck to color patterns, where for example different-colored insoles are intended for different types of treading, without even knowing what an indented, neutral or supinated footprint is.

And once we play at that point, the biggest goal of Bike Fit is to adjust the bike, never forget that. The moment the goal becomes the cyclist, the process becomes more specific. For example, if a cyclist has a pronounced footprint associated with a muscle shortening and as a consequence his knee goes too far from the frame, what is the problem with that customer pedaling like that if it does not cause him any damage?

If a cyclist has a difference in leg length and his body is already adapted to this specificity and this does not cause him injury, since the body”learned” to compensate for this difference by modifying the angle of the ankle, for example, what the problem?

The problem is often to modify these positioning angles. At first the athlete up can increase a few watts of power, but in the long run can cause injuries of high gravity. Only a professional with adequate training to know when to treat the source of the problem and when to treat the problem.

So, reinforcing that equipment by itself does not do any miracle.

It is very important to know if the professional has attended a faculty in the area of ​​biomedical with emphasis in the area of ​​health. We studied fundamental disciplines for the good understanding of anatomy, morphology and musculoskeletal kinetics. If the course that he performed of Bike Fit is free of commercial interests in sales of bicycles and their components.

So when doing a Bike Fit, think about it! Think not only in a few seconds more you want to get, but in your body, your health – make the right choice!(I.e.
