The Undercover Hers is the 160g proof that a sleek and superlight women’s saddle can be ultra-plush. Utilizing a saddle base structure that integrates active suspension functions with seating support, the Undercover Hers achieves extraordinary plushness without the bulk of conventional saddles. The result is a women’s saddle with remarkable sleekness allowing unrestricted movement on and around the seat, with cushioning and shock absorbing capabilities exceeding saddles twice its weight.

Carbonite SpyderWeb Base
A flexile foundation for unparalleled shock absorption.

Unique cutouts on the base designed to compress upon impact and quickly rebound for continuous shock absorption. The spring-like structure stays active throughout the ride, soaking up bumps more efficiently than foam padding alone. The SpyderWeb base, made from proprietary material formulated for high resiliency and impact resistance, is a finely tuned suspension component designed to cushion impacts in higher frequency with minimal padding.


More cushion where you want it. Less padding where you need it

The Bio-X is a padding system shaped to complement the body's natural anatomical riding positions, resulting in some areas benefiting from extra cushioning and others with less – just as it is with the human body.

Proper cushioning is essential for the perineal region, the area between our sit bones packed with sensitive tissues, nerves, and blood vessels that cannot endure pressure. Applied pressure in this fragile zone over time can reduce blood flow, cause numbness, and the possibility of nerve damage.

The areas above the rail receptacles, generally the most rigid points on the saddle, will benefit from extra cushioning. Though these are not typical seating surfaces, proper cushioning becomes indispensable should riding maneuvers shift to sitting over these points, even for brief moments.

Less padding underneath our sit bones is ideal. Covered by mostly fat and muscles, the sit bones are naturally capable of sustaining the full body weight when seated. Thick padding in this area ends up adding pressure to the perineal from excess padding pushing up against the sensitive areas when seated.

The unique sculpting of the Bio X-Pad shape adds extra cushioning in the mid-section that better insulates the sensitive areas, thinner padding underneath the sit bones to prevent excess padding from bunching up against places it shouldn't, and thicker over the rail receptacles to cushion potential impacts. pushing up against the sensitive areas when seated.

Two types of X-Pad


a closed cell EVA foam that's denser, with faster rebounding characteristics. SL foam is substantially lighter in weight.


an open cell foam that's softer, offering more conformity. ReActiv foam weighs a little more than SL and is more economical.

Performance Shape

Performance comfort, logically shaped for women

The defining trait of the Undercover Hers is its sleek profile and wide seating surface. The base is purposefully designed with a less central curve to minimize pressure on soft tissues, complementing the flatter base is padding shaped with varying cross-sectional radii gently matching the 3D curvature of the sit-bones. In natural seating position, the sit-bones smoothly self-align with this curvature to reduce concentrated pressure. When maneuvering off the saddle, the dropped tail and downward sloping nose both stay out of the way. In concert with SpyderWeb base suspension technologies, the Undercover Hers blissfully balances performance and comfort like no other.
