Fizik saddles: Spine Concept EVO

Spine Flexibility and Pelvic Rotation are inextricably linked to saddle comfort—How flexible your spine is and by how many degrees your pelvis rotates determines which saddle and components fit you.

Snake

High body flexibility and no pelvic rotation^* whilst pedaling. You need a flat saddle.

Bull

Low body flexibility and high pelvic rotation^* whilst pedaling. You need a waved saddle.

Chameleon

Medium body flexibility and low pelvic rotation^* whilst pedaling. You need an in-between saddle.

^*Pelvic rotation is the position of your pelvis on the saddle, anterior (rotated forward) or posterior (rotated backwards).
