Specialized just dropped what might be its most refined saddle yet: the S-Works Power EVO Mirror. It builds on the foundation of the already popular S-Works Power Mirror but dials up the comfort, adjustability, and rider personalization to new heights. And while the original Power with Mirror was all about keeping you locked into one powerful position, the Power EVO lets you move more freely, without sacrificing support.
Mirror, Mirror, But Even Better
At the heart of the EVO is Specialized’s patented Mirror technology, a 3D-printed honeycomb matrix made from liquid polymer. The structure allows for precision support and pressure relief that foam can’t replicate.
In the S-Works Power EVO update, this technology takes a next-level step: 47,000 struts and 21,000 nodes comprise the support system (compared to just 14,000 and 7,799 in the original Power Mirror).
The result is a saddle that delivers 28.8% less sit bone pressure, 34.1% less nose pressure, and 18% less midline pressure than foam-based designs. And yes, that’s a noticeable difference on the road, and the trainer (will it ever stop raining?!).
Furthermore, the Mirror material is now 40% bio-based, enhancing sustainability while reducing moisture absorption and improving durability. Whether it’s sweat, sunscreen, or chamois cream, this saddle shrugs it off, rather than getting stuck or discoloring like previous versions.
Longer Rails and Wider Nose
One of the most significant changes is in the rails. The Power EVO now features 2cm longer carbon rails, giving you 70mm of clamping space (versus 50mm on the original). That’s a big win for riders who need more adjustability or prefer a more aggressive forward position.
The invisible cutout (a redesign of the midline channel) eliminates harsh edges and delivers a hammock-like feel that better distributes pressure. Combined with a wider nose (1 cm wider than the original) and a refined wing flare, the Power EVO is specifically designed for riders who shift their weight forward and backward throughout the ride.
It’s still 24cm long like the original Power, but the EVO’s new shape is tuned for dynamic movement. It reminds us a bit of the Bontrager Aeolus RSL in terms of forward support, but this one feels cloud-like by comparison.
Built for Performance, Not Just Comfort
All the comfort in the world doesn’t matter if the saddle holds you back when it’s time to push. Fortunately, the Power EVO’s flex-tuned carbon shell effectively dampens vibrations (similar to the CADEX saddles we reviewed), and its 7×9 carbon rails are lightweight, providing support for the carbon hammock.
Weight: Specialized S-Works Power EVO Mirror
- 130mm: 212g
- 143mm: 218g (tested)
- 155mm: 229g
- 168mm: 243g
That makes the 143mm model just 31g heavier than the standard S-Works Power with Mirror, a worthwhile trade for the increased comfort and adjustability IMO.
Fit With Four Widths
The Power EVO is available in four widths—130, 143, 155, and 168mm—to accommodate a broader range of body types and sit bone widths. Whether you’re racing road, ripping gravel, or clocking trail miles, there’s a Power EVO with your name on it.
That said, Specialized does not recommend this saddle for use in gravity or downhill conditions, and it’s not certified for e-bike loads due to its carbon rail construction.
First Ride Impressions
This is, without question, the softest-feeling 3D saddle I’ve tested. The Mirror material feels almost like fabric—lush and forgiving without being spongy. It doesn’t interfere with shorts (regardless of material), unlike some other 3D-printed saddles we’ve ridden.
Out of the box, it’s noticeably more comfortable than the original Power with Mirror. While that saddle locked you into one spot, the EVO gives you freedom to move, without compromising on support. It’s excellent on the nose (where I tend to migrate on climbs), and the material creates a surprisingly comfortable perch for both locked-in and all-out efforts.
Still, the wider nose does take some getting used to. It’s a bit broader than the original, and you’ll notice the difference when shifting positions. Specialized Power saddle users might feel more confined with less thigh glide area, but give it time—it starts to feel natural after a few long rides.
Less Special Treatment
Compared to the Power Mirror we reviewed previously, the Power EVO requires less adaptation. Your sit bones don’t sink into it; they almost levitate, floating over small bumps with subtle compliance. It’s hard to describe, but it feels like suspension built into the saddle, all without needing to tweak tilt or position based on material firmness.
The Mirror material itself is incredibly soft, and it has the most fabric-like feeling 3D saddle I’ve experienced. It’s lush and supremely comfortable. While the 1cm wider nose is still something I’m adapting to, the overall feel is closer to a Bontrager Aeolus RSL—but far more cloud-like in support. The material’s plushness stands out on every ride, making it feel more like a luxury component than a performance tool.
Final Word
Specialized has been refining the Power saddle line since 2014, and the S-Works Power EVO with Mirror feels like the most complete execution yet. It blends the best of their pressure-mapping science with rider feedback from the pros, delivering a saddle that’s more supportive, more adaptable, and yes, more comfortable.
How Do I Know What Power to Choose?
Saddles are a highly personal component, one that “works awesome” for your friend might be an absolute nightmare for you. I suggest marking out the most meaningful needs and then seeing the saddles in person. If the OG standard Power Mirror didn’t quite click with you, or if you want a saddle that offers more flexibility in positioning without sacrificing comfort, the EVO is worth considering. This comparison sheet from Specialized helps lay out the details:
If you can put a price on comfort, this saddle sets the bar at $475. That’s a serious chunk of change for a saddle, no question. It reminds us of the $575 Wove MAGS saddle we reviewed in the past—ultra-comfortable, but almost untouchable because of the price.
Still, if you find a saddle that works for you, it’s money well spent. And if Specialized has taught us anything over the years, this cutting-edge tech might eventually trickle down to more wallet-friendly tiers. Fingers crossed.
