Lightweight support for low, aerodynamic riding positions.

The Specialized S-Works Romin EVO with Mirror combines the Romin’s long, curved profile with a full 3D-printed Mirror pad. It is designed for riders who rotate their pelvis forwards into a low road or gravel position while still wanting room to adjust their position along the saddle.

Mirror technology replaces conventional foam with a precisely tuned polymer structure containing 22,200 struts and 10,700 nodes. Combined with the concave FACT carbon shell, this creates Specialized’s thickest Mirror pad and distributes pressure across a wider area. Specialized’s testing showed up to 26% less sit-bone pressure compared with a traditional foam saddle.

Key Features

• Long, curved Romin EVO profile supports forward pelvic rotation
• Designed for low, aerodynamic and performance-focused riding positions
• Full Mirror pad uses a 3D-printed liquid-polymer structure
• 22,200 struts and 10,700 individually tuned nodes
• Specialized pressure mapping reports up to 26% less sit-bone pressure than traditional foam saddles.
• Supportive Body Geometry cutout helps relieve soft-tissue pressure
• Body Geometry design is lab-tested to help maintain blood flow
• Concave FACT carbon shell provides space for a deeper Mirror pad
• Flex-tuned shell balances firm support with controlled compliance
• Ultra-light oversized FACT carbon rails
• SWAT-compatible mounts allow compatible storage beneath the saddle
• Available in black

Size and Weight

• 143mm — approximately 190g
• 155mm — approximately 198g
• Rails — oversized FACT carbon, 7 x 9mm
• Shell — concave FACT carbon fibre
• Padding — full 3D-printed Mirror structure

Published weights may vary slightly between individual saddles.

Carbon Rail Compatibility

The oversized 7 x 9mm carbon rails require a compatible seatpost clamp. They are not compatible with side-loading clamps designed only for standard 7mm round rails. Check your seatpost compatibility before fitting or ask our workshop team for advice.

Why Choose the Specialized S-Works Romin EVO with Mirror?

Choose the S-Works Romin EVO with Mirror if you prefer a curved saddle, ride in a low position and want the lightest Romin with Mirror construction. Its traditional length provides space to move forwards during high-power efforts or backwards when climbing and settling into a steady pace.

The S-Works model uses the same Mirror pad as the Romin EVO Pro with Mirror but replaces its titanium rails and carbon-reinforced nylon base with a FACT carbon shell and carbon rails. This reduces weight by approximately 49g in the 143mm width.

For most riders, the Pro model offers a more practical balance of price, durability and seatpost compatibility. The S-Works version makes the most sense when low weight and full-carbon construction are genuine priorities.

Free Retül Digital Sit-Bone Measurement

Mirror technology cannot correct the wrong saddle width or an unsuitable shape. Choosing between 143mm and 155mm should be based on your sit-bone measurement, riding position and pelvic rotation—not your body size or the width of your existing saddle.

Our Thoughts

The S-Works Romin EVO with Mirror is best suited to riders who naturally rotate forwards and want a saddle that supports that position. Its curved profile helps stabilise the pelvis when riding low, while the longer shape still provides room to move during climbing and harder efforts.

This is not automatically the most comfortable option simply because it is the most expensive. Riders who prefer a flat platform may suit the Phenom better, while those who like a shorter saddle and remain centred in one position should consider the Power.

The S-Works model is impressively light, but the correct shape, width and setup are still more important than saving weight. Saddle height, setback and angle should be checked when changing from a foam saddle because the deeper Mirror structure may alter how the rider sits relative to the pedals and handlebars.
