TWO WAYS TO SELF-REGULATE YOUR ROAD BIKE SEATPOST HEIGHT
The seatpost is very important on a road bike, because it connects the saddle to the bicycle. So an optimal seatpost height can boost your pedalling, enhance the comfort of your ride and, most importantly, reduce damage to the lower back.
There are some methods for self-regulating the seatpost height. The first and most common, is to sit on a bike on a turbo trainer, holding on to a chair or table. Place your heel on the pedal and pedal backwards to reach the “six o’clock” position. Your leg should be fully extended without any drop in the hip. If your knee is still bent you need to increase the height, adjusting in small increments each time. Pay attention: if your heel loses contact with the pedal, you need to lower the seatpost.
Another more scientific method , is based on measurement and was invented in the 80s by the old, French champion Bernard Hinault and his coach. To find the initial number stand with your feet hip width apart , making sure you have your shoes off. Measure from the crotch to the floor, and this will give you your inseam measurement. Then multiply this by 0.885 and apply to your saddle height. Take care, this method is not so precise. If you are looking for the best regulation of your seatpost, the best way is to contact a professional mechanic or a biomechanic.
