“What is my saddle size?”
This is a question we get asked a lot.
Measuring the ischial tuberosities to determine saddle size only provides an initial, general estimate of the approximate size you could use. This measurement can vary significantly from saddle to saddle, mainly for two reasons:
– The rotation of the pelvis that is done on the saddle.
When you are sitting on the bike, it is different from when you sit on a “stool” for measuring the ischial tuberosities… Therefore, there is a direct interference in the said width of the ischial tuberosities versus the saddle.
Even knowing the approximate measurement (let’s imagine 143mm), for this saddle size there are hundreds of models, where the support on the ischial tuberosities differs greatly in all of them.
In short, the best way to know which saddle is ideal is by testing the pressure exerted on each saddle, through a saddle pressure test and subsequently testing it in the field.
