Smiling Butt Kit accuracy
A recent clinical study showed just how precise our Smiling Butt Kit is. By using our one-of-a-kind process we can achieve a precise measurement of your butt (within 1mm), all from the comfort of your home. With other standard measures there can be errors of up to 20 mm.
Saddle width importance

But I don't sit on my bike in an upright position...
We are aware of the difference of the posture while taking the measurement and of sitting on the bike. This is why we combine the measured value with other parameters (flexibility, riding style, bike type) to adjust the value and make the custom saddle in perfect width for you and your riding preferences.
