How to adjust the height of your bike's saddle? Calculation of the ideal height

Most likely the first decision you have to make after buying a bicycle is to adjust the height of the saddle. But do you already know how to calculate the height of the saddle, the setback or the distance between it and the handlebar?

Placing the post a little higher or lower can be much more important than it seems a priori, and if you want to prevent back problems, cervical pain or muscle overload, you should pay special attention to the placement of the saddle. A few sad centimeters can be the long-term difference between suffering an injury or not and especially between getting more or less performance in each of your pedal strokes. Pedaling efficiency begins with the correct placement of the saddle, the cyclist's main point of support on the bicycle.

We did not want to go into the matter without first reminding you that the advice and practices discussed in this article are indicative and that to know with total certainty the measures that best suit your body, you should visit a biomechanist who, as a specialist in the sector, can offer you a diagnosis more limited to your measurements.

Calculate the height of the bicycle saddle

If you want to adjust the height of your bicycle's saddle as well as possible, you should start to stop paying attention to the advice and topics that you may hear about the subject. There are many theories about calculating the ideal height, but the truth is that many of them are completely unfounded.

Although the advice that we give you below is indicative, it is a good way to follow for all those people who do not have the remotest idea of ​​how to calculate the height.

The first thing you should do is measure your crotch in centimeters with the specific bicycle shoes. The data you obtain must be carefully stored since the final height will come out of it.

How to measure the crotch?

To measure the crotch, it is enough to stand completely upright and with your legs closed in front of a wall and measure the distance between the ground and your crotch right at the point where you would rest the saddle of your bicycle. If you have difficulty taking the reference, you can use the spine of a book placed just below your genitals.

Once you have the centimeters of your crotch, you will multiply the value by a correction coefficient of 0.885 and the result obtained will be the height at which you must place the saddle.

To measure the height at which the saddle is placed, we must calculate the distance from the center of the saddle axis to the center of the bottom bracket axis. It is very important to be clear about the measurement points so as not to make any nonsense.

Forward, backward and tilt of the saddle.

For a correct placement of the bike saddle, it is not only important to calculate its height well. It is also essential to position the saddle correctly both in its inclination and in its advance. Two fundamental aspects both to guarantee the comfort of the cyclist and to ensure a healthy physical activity without risk of injury.

To calculate the setback of the saddle on the bottom bracket (which would mean pulling the saddle further forward or further back) it is enough to throw a plumb line with the cranks completely parallel to the ground and try to make the line that comes out of our knee cross the center of the pedal as tight as possible. In this way and in a fairly general but practical way, we will find a good point in which to fix our saddle. Obviously prior to this we must calculate the height of the saddle, never do the procedure the other way around.

Once we have calculated the ideal height, we will be in a position to determine the retreat and/or advance.

In reference to the inclination, we must say that as a general rule it must remain completely perpendicular to the ground and that although the saddle can be tilted depending on certain personal needs, the general rule should be maintained as far as possible.

Despite everything, it is common, especially in men, to tilt the saddle slightly towards the ground to avoid possible prostate problems. In this sense, antiprostatic saddles were invented with the peak slightly inclined towards the ground, with the intention of freeing the perineal area and reducing genital numbness.

Distance between saddle and handlebar of the bicycle

To calculate the distance between the saddle and the handlebar, it is enough to measure the space between the tip of the saddle and the axis or center of the handlebar. A distance that will be conditioned by the height at which we have placed the saddle.

As a general rule and as a guide we can say that the distance should be between 50 and 60 centimeters so that if you decide to place it at 55cm it is very likely that. Although it is not your ideal position, you are not committing anything barbaric with your position. We take this opportunity to remind you of the importance of visiting a trusted biomechanist who, as a professional in the sector, will adapt your bicycle to the millimeter.

If we do not choose the distance between the saddle and the handlebar well, it is very likely that we will find ourselves with significant physical discomfort in the long run.

If there is too much distance between the handlebar and the saddle we will surely begin to suffer from back problems and overload in the lumbar area, while if the distance between the handlebar and the saddle is too small we will be losing pedaling efficiency and almost certainly the maximum power will be reduced. will be seriously diminished.

The most comfortable solution to correct this problem may be to change the power. And choose a shorter or a longer one depending on your needs. Simply by changing the stem of your bike you can modify those decisive centimeters that will offer you greater comfort in your pedaling.
