Balanced support with plenty of room to move.
The Specialized Phenom Pro with Mirror combines the Phenom’s long, flat profile with a full 3D-printed Mirror pad. It suits riders who prefer to move forwards and backwards on the saddle as their effort, gradient or terrain changes.
Mirror technology uses a liquid polymer to create a precisely tuned structure containing 20,055 struts and 8,735 nodes. Combined with the concave shell, this provides deeper support beneath the sit bones and reduces pressure without relying on thick, conventional foam. Specialized’s pressure mapping showed a 28% reduction in sit-bone pressure compared with a traditional foam saddle.

Why Choose the Specialized Phenom Pro with Mirror?
Choose the Phenom Pro with Mirror if you want a flatter saddle that allows more movement than the short-nose Power or curved Romin EVO. Its 270mm length gives you room to move forwards during harder efforts and back again when climbing or settling into a steady pace.
The hollow titanium rails and reclaimed carbon fibre shell make the Pro model a practical choice for regular road, gravel and off-road use. It is heavier than the S-Works Phenom with Mirror but avoids the seatpost compatibility considerations that come with oversized carbon rails.
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 how much you naturally move on the bike—not your body size or the width of your existing saddle.
Visit Chain Reaction Christchurch for a free Retül Digital Sit-Bone Measurement. Our team can measure your sit bones, discuss how you sit on the bike and help determine whether the Phenom shape and width are right for you.
Our Thoughts
The Phenom Pro with Mirror is a strong option for riders who dislike feeling locked into one position. Its flat profile makes it easier to move along the saddle, which works particularly well on gravel bikes, cross-country bikes and trail bikes where your position regularly changes.
It can also work very well on a road bike for riders who prefer a flatter platform. If you want a shorter saddle that holds you in a more centred position, look at the Power. If you rotate further forwards and prefer more curve beneath the pelvis, the Romin EVO may suit you better.
The Pro model is the sensible choice for most riders wanting the Phenom shape with a full Mirror pad. Correct width, height, setback and angle still matter just as much as the saddle technology.
