Which saddle width do I need?

Specialized sizes saddles by your sit-bone width. Measure it at a Specialized dealer, or at home: sit on a piece of cardboard on a chair with your knees at 90°, mark the centre of each sit-bone impression and measure between the dots. Then use Specialized’s own mapping in the size guide on this page: up to 100 mm → 130 mm saddle, 101–120 → 143, 121–140 → 155, 141–160 → 168, 161–176 → 180, 177–195 → 200. If your width isn’t made in that model, Specialized’s size tool picks the nearest one available.

Mirror, MIMIC or foam: what’s the difference?

Mirror is Specialized’s 3D-printed padding, a honeycomb lattice printed from liquid polymer whose density is tuned zone by zone for sit-bone support; Specialized claims clear pressure reductions over foam (for example up to 26% on the Romin EVO). MIMIC is a multilayer soft-tissue technology that Specialized developed for women, to maintain equilibrium and reduce swelling in soft tissue. Foam saddles use Specialized’s padding levels, from Level 1 (lightest, most direct) to Level 5 (softest, for casual riding).

What does Body Geometry mean on a Specialized saddle?

It is Specialized’s ergonomic design method since 1997: saddles are developed with pressure mapping, anatomical measurement and testing with pro and everyday riders, and Specialized says its patented Body Geometry designs are lab-tested to ensure blood flow to sensitive arteries. These are Specialized’s claims; saddle comfort is personal, so the right width and shape for your position matter most.

Specialized: sit on a piece of cardboard on a chair with your knees at 90° (raise your feet if needed), stand up, mark the centre of each sit-bone impression and measure between the two dots. If a width isn’t made in a given model, Specialized’s size tool picks the nearest width that model comes in. A Specialized dealer can also measure your sit bones.

How to measure

Chest: around the fullest part, under the arms. Waist: around your natural waistline. Hips: around the fullest part. Keep the tape snug but not tight.
