Lightweight race performance with precisely tuned Mirror support.
The Specialized S-Works Power with Mirror combines the familiar short-nose Power shape with a 3D-printed support structure designed to distribute pressure more evenly across the saddle.
Mirror technology replaces conventional foam with a polymer matrix containing 14,000 struts and 7,799 nodes. Different areas can be tuned independently, providing firm sit-bone support while allowing more compliance where pressure relief is needed.
A flex-tuned FACT carbon fibre shell and oversized carbon rails keep the weight low, making this a premium option for road, gravel and XC riders who already know that the Power shape suits them.

Important Rail Compatibility
This saddle uses oversized 7 × 9mm carbon rails. Your seatpost must have a compatible carbon-rail clamp.
The rails are not compatible with seatposts that use side-loading clamps designed only for standard 7mm round rails. Check your seatpost compatibility before fitting the saddle and always follow the recommended carbon-rail torque setting.
Why Choose the Specialized S-Works Power with Mirror Saddle?
This saddle suits riders who like the stable support and short nose of the original Power but want better pressure distribution without adding unnecessary weight. The Mirror matrix supports the sit bones across a broader area than conventional foam while retaining the direct feel expected from an S-Works performance saddle.
It is particularly well suited to riders who spend time in a low or forward position. However, the Power shape will not suit everyone. Riders who move around considerably or prefer a longer platform may be better matched to a Phenom or Romin saddle.
Free Retül Digital Sit-Bone Measurement
Choosing between the 143mm and 155mm widths should be based on your sit-bone measurement and riding position, not your body size or the width of your current saddle. Even the most advanced saddle will be uncomfortable if it is the wrong width or positioned incorrectly.

Our Thoughts
The S-Works Power with Mirror is a genuine performance saddle, not simply a softer version of the standard Power. Its main advantage is how the Mirror structure distributes load while the carbon shell and rails keep the saddle exceptionally light.
It is an excellent option for riders who already get on well with the Power shape and want the lightest Mirror-equipped version. If weight is less important, the Power Pro or Power Expert with Mirror may offer better value and more practical rail options. Correct width, angle and fore-aft position remain essential—the Mirror material cannot compensate for a poorly fitted saddle.
