In practice there is an easy way to determine the proper height of your bike saddle, The correct saddle height can be set by using the so-called heel method; sit on your bike, put your heel on the centre of your pedal and extend your leg. If the saddle is adjusted too low, your leg is slightly bent and not straight. However, if the saddle is set too high, you will not be able to reach the pedal with your heel. If your leg can be easily extended without discomfort, your saddle height is perfect.
Measuring and calculating
An incorrect bicycle saddle height can quickly lead to pain in different parts of your body; something we will cover in much more detail later. When setting the optimal saddle height, it is also important to pay attention to the movement of your hips. If you feel your hips rocking and shaking a bit while cycling, you need adjust your bike saddle. The optimal saddle height can also be calculated. Proceed as follows: Measure your stride length and multiply the stride length ((length between the crotch and the sole of the foot) by 0.885. This calculates the distance between the top of bicycle saddle to the center of the bottom bracket, after which the optimal saddle height can be set.
To set the seat post lower or higher, you need a suitable Allen key. By loosening the seat post clamp (sometimes via a bolt and other times via a quick release lever) the seat post can be pushed deeper into the seat tube or pulled further out of the seat tube. If required you can also pull the seat post completely out of the seat tube and replace the seat post. If you tighten the seat post again always respect the torque specifications on the clamp. However, there is always an adjusting screw or bolt at the bottom of the bike saddle which can only be loosened and tightened with an Allen key. This screw can be used to set the tilt and the fore-aft position of your bike saddle.
The adjusting screw at the bottom of your bicycle saddle should therefore also be loosened if you want to replace your bicycle saddle. After mounting the new saddle and setting it right, the adjusting screw of your bike seat should be tightened again to ensure you can make your rides safe and sound.
