We’ve all got different bone structures, which ultimately determine our body size, independent of diet. These is one of the factors in determining fit, from clothing to even saddles. These bone structures are known as Somatotypes and come in three varieties; Ectomorph (Light bone structure) Mesomorph (Average bone structure) and Endomorph (Broad bone structure).
Fabric Saddles takes a look at how your Somotype determines your sit-bone width and sizes you off of your height and wrist circumference.
Their line is taking shape and will be available in early 2015. For now, head over to Fabric and check out their saddles. The Cell and ALM models look interesting.
