How do you choose the right bicycle saddle? Step 1

by Kathrine Pedersen |

1. Measure the distance between your Sit Bones, also known as Ischial Tuberosity. This is to find the RIGHT SIZE SADDLE for you to ensure you get adequate support - anatomical.

Some bike shops provide the technology to measure you in their store either by sitting on a gel seat or using a digital measure, however you can DIY at home. Simply take a piece of cardboard, place it on a hard surface like a bench or stool and sit on it with your knees at a 90° angle. Then raise your heels up for a few seconds until you feel your sit bones have made an impression on the cardboard. Stand up and use a marker to find the middle of the 2 indentations you have made on the cardboard. Mark them with a dot. Use a tape measure or ruler to measure the distance between these two dots and this is your Ischial distance which will gage if you need a small, medium or large saddle size (width). Please note, a lot of women are 130mm or more irrelevant of their body size, because anatomically they need to have a wider structure to ensure humanity carries on…

Below are Sit Bone Measurements and approximate saddle sizes to aim for: BUT, please remember to incorporate riding position as well (see step 2.) as this will help determine the Saddle Shape for you.

Small = < 110mm (Saddle sizes 125mm - 170mm)

Medium = 110 – 130mm (Saddle sizes 145mm - 195mm)

Large = > 130mm (Saddle sizes 160mm - 225mm)

We have not included measurements for "Cruise" saddles which go up to as wide as 335mm and are not regarded as long distance cycling saddles.
