The S-Works Power Mirror Saddle is the perfect reflection of you. Specialized is redesigning comfort and performance with their new Mirror technology in order to take Body Geometry into the future. In this next generation of saddle technology specialized developed mirror technology by 3D printing a liquid polymer to perfectly reflect human anatomy. 

Using the 3D printing process Specialized has created a complex honeycomb structure that allows infinite tune-ability of the material density never before thought to be possible. The result is a matrix of 14000 struts and 7799 nodes, each of which can be tuned individually.

Combining this technology with the already world renowned S-works Power Saddle, produces a high performance saddle that is specifically designed to help you perform at your best. 

Note: 7 x 9mm carbon rails require a compatible seatpost clamp or an adapter kit.

Specialized S-Works Power Mirror Saddle (Black) (Carbon Rails) (155mm)
I purchased this saddle along with other styles from Specialized, Serfas, and Selle SMP. In my view, there is no such thing as a comfortable saddle. Resting most of one’s body weight on two small sit bones with a relatively small surface area, is just going to cause a certain amount of discomfort on long rides. So I have been looking for both VERY LIGHT and comfortable enough that I don’t think about my saddle on rides of an hour or less. Of the 7-8 highest priced, expected-to-be-the-most-comfortable, saddles that I have tried so far, all have done pretty well, but this Specialized Mirror saddle has a slight edge as the best so far. As far as cost, yes it’s pricey, but if you buy a very expensive bike, what are you willing to pay for whatever is the least uncomfortable saddle? The saddle is too important to compromise in that area on an expensive bike.

Not what I was expecting about this saddle for this price, it’s not the most comfortable and they don’t offer a free return for this product that it’s supposed to be the best saddle in the market and the most expensive I’m very disappointed with the saddle and with the company, I’m a big buyer for this company, AMAIN has to check the policy return, amazon offer free return for all the products if you don’t like it free return and your money back warranty.

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.
