What do you get for your money?
The Mirror saddle is built using a technology from the
appropriately named USA brand 'Carbon' and is 3D printed
using 14,000 struts and 7,999 nodes (the connection points between
This creates a lattice structure that can be made firm in some
areas and soft in others; perfect for a saddle which wants to
support your sit bones but conversely be invisible to your 'bits'
(to use a highly scientific anatomical term!).
Specialized's Body Geometry programme informs all their contact
points, in terms of both shape and size, and they've drawn on their
wealth of experience from bike fit specialists and sister company
Retül to generate a shape that is intended to "mirror" your own
anatomy (hence the name).
The Mirror is a stock saddle currently (albeit an amazing one),
with a choice of 143mm and 155mm widths, but the really exciting
logical progression would be to do a saddle fit and then a custom
3D printed saddle is made for you.
The production version took 70 iterations to get right.
Apparently they went from a 3D render on a computer screen to the
first rideable sample in 24 hours- the joys of 3D printing. It's
all very F1; where they will make new wing parts for the cars based
on driver feedback and install new changes next day.
It certainly looks high tech; the lattice structure is very
impressive to behold and it's bonded onto a top of the range
S-Works shell and carbon rails.
It also looks 'substantial' - in the picture below you can see
just how much bigger it appears compared to a conventional Power
saddle. Standing 6mm higher than a normal Specialized Power saddle
you'll need to lower your seatpost accordingly!
At 190/194g for the 143/155mm sizes respectively this isn't
intended to be an ultralight model. The 3D printing and "airy"
appearance are in the service of comfort and efficiency rather than
weight savings. The weight is quite respectable, but weight weenies
will still prefer the 159/161g of the more conventional carbon
S-Works Power saddle.
