Specialized Power Pro Mirror Saddle Description:

Top-level comfort meets durability and performance with the Specialized Power Pro Mirror Saddle. Built around Specialized's Power saddle shape, the Power Pro Mirror uses 3D printed liquid polymer to create a fine-tuned honeycomb structure that is supportive and ergonomic – helping you to put out more power and ride longer. With durable titanium rails, the Power Pro saddle is a great option for mountain bikers as well as roadies – because off-road comfort is important too. To make the production of the saddle more sustainable, Specialized uses reclaimed carbon fiber to construct the saddle's base – minimizing production waste. Race-ready, the Power Pro Mirror weighs in at just 245g for the 143mm width version.


  • Body Geometry design is lab-tested to ensure blood flow to sensitive arteries
  • Mirror technology utilizes 3D printing from liquid polymer to create a one-of-a-kind honeycomb structure that offers superior sit-bone support and comfort

  • SWAT-compatible mounts molded into the saddle base allow for sleek and integrated storage solutions

Please disregard these as the Power Pro Mirror Saddle has titanium alloy rails that measure 7 x 7mm and are compatible with nearly all saddle clamps.

Specialized Power Pro Mirror Saddle (Black) (Titanium Rails) (3D-Printed) (143mm)
This is my second Power Pro Mirror Saddle. I have a closet shelf lined with saddles that I’ve used, suffered with, and ultimately rejected over the years. That along with experimentation with various designs of chamois in high quality bibs has not cured the pain that greets my boney a** after a couple hours of riding. That’s until this technology became available to us mortals. My recent century ride resulted in sore legs and rabid thirst without consideration of my hind end whatsoever. The ride sensation is as if there’s 15 psi less in my tires. On pavement I have no issues moving about the saddle, admitting there’s little movement to be made. On the bike that’s in the trainer however, I seem stuck in one spot. Having used the saddle over 2K miles, there’s no noticeable extra wear on my bib shorts. Each rider of course has their preferences, but so far I can say this is the best add-on I have EVER made. It took a MAJOR discomfort right out of the loop permanently. No more need to experiment or spend another penny on saddles - except for that N+1.
The shipping from Performance Bike was faster than other vendors I have used. Ordered on Tuesday, had it Friday. “Rushed” free shipping.

Oddly, this saddle feels harder than the Specialized Power Pro I had previously. Perhaps it's because the previous saddle was worn and more pliant. I have the saddle a zero degrees, but will see if lower the nose 1-2 degrees helps. Overall, not as comfortable as I anticipated.

Great product BUT you need to be comfortable with a saddle that "grips" - there is no sliding around to adjust position.

So far this saddle has provided great comfort and feel. I have 4 rides in so far, the longest being 57 miles. More rides to come, longer rides and I expect the same confutable ride.

Great ergonomics went in to this product, it's understood that people will pay for quality, especially when it comes to comfortability wether it be a car or a couch, this saddle is everything thing that I expected, kudos to specialized for hitting the mark with this saddle, my undercarriage thanks you.

How To Determine Sit Bone Width:

  • 1. Place large piece of cardboard on chair. Place small piece of cardboard lengthwise on large cardboard, where you'll be sitting. Sit on small cardboard with knees at 90º to the floor (use a block or prop under feet to raise them, if necessary). Pull up on chair to create sit bone impression. Stand up when done.
  • 2. Grab small cardboard and marker. Feel cardboard for impressions. Mark a vertical line on each side of left and right sit bone impressions. There should be four lines on cardboard. Make a dot in the center of each sit bone impression. Measure the distance between dots.
Saddle Width:Sit Bone Width:

*Some Specialized Saddles are not available in 168mm. In this case, consider the 155mm version.
