What Influences Width?
Saddles come in a huge variety of shapes and designs. So the width of saddles is also hugely variable. If they are all trying to do the same job why are they so different? There are several things that will influence the width of a saddle.
Gender – There is a physical difference between the widths of men and womens pelvic structure. The majority of women are normally wider (this is not true for all women). You may need a womens saddle that has a wider width than a mens saddle.
Type of Riding – The interest in doing different types of riding has lead to different types of bikes being made. These different bikes put riders in different body positions so the points of contact under them are different. Which has lead to different saddle shapes to get the best outcome for the body position you are in when on your bike. The more forward bent you are the narrower your saddle will be.
Time on the Bike – As you spend longer on the bike the type of saddle that you need tends to change. So there are also differences between recreation and endurance saddle shapes. In terms of width, saddles need to provide the right support without interfering with repetitive pedalling.
