Power Arc Expert Saddle

If you were a big fan of the original Power saddle, you might be pleasantly surprised by how much more comfortable it can get. The Power Arc Expert Saddle features the same channel and length as the original, now with curved Body Geometry technology and more durable Cr-Mo rails. What does this mean? It means you can ride for miles with an in-saddle feel, as opposed to a stiff, uncomfortable on-saddle feel.

Body Geometry provides personalized comfort and support that's ergonomic and lab-tested. Lightweight padding is strategically placed to alleviate pressure and assure blood flow to sensitive arteries, in men and women alike. Body Geometry saddles ensure proper support when riding in the correct position, and they come in multiple widths to support differing body types.

  • A comfortable saddle for longer rides
  • Proprietary Body Geometry design relieves saddle fatigue
  • Lightweight PU padding adds comfort and support
  • Hollow Cr-Mo rails are lightweight and durable
  • Level II padding built with medium density foam
  • SWAT-compatible mounts are molded in to add storage options
  • Item #SCQ00D1

The Power saddle for Romin users

I've put it through the wringer
Size Bought
5` 6"
150 lbs

I've ridden tens of thousands of miles on the Specialized Romin, but was getting some hot spots while doing lots of trainer time during lockdown, and figured it was time to look for another saddle. Of the Power saddles, the Power Arc is the one you want if you like the Romin. I found the standard Power saddle unbearable. Too flat across the sit bones for me. But the Power Arc is much better; closer to the Romin, and my preferred saddle for trainer time and long days on the road.


The expert should have hollow titanium rails, as the picture shows, no? Description says chromoly rails.
