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 Hollow Ti 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 Ti rails are lightweight and durable
  • Level II padding built with medium density foam
  • SWAT-compatible mounts are molded in to add storage options

Power refined

True to size

Sit bone width 113 Saddle width 143 After spending a season on the Specialized Power Saddle, I found that there were some pressure points that developed for me over some of my longer rides. After a bit of research I found that the Specialized Power Arc saddle was specifically with a different curve than the original Power saddle. This means that if you want a Power saddle but you felt like the original power didn’t fit well for you, then this is your answer. For me this was the case. I found that I was able to ride on this saddle more comfortably and for longer than I was able to ride on the sister saddle. I also found that by comparison, I lost none of the gains in power that the saddle allowed me to have. That being said, this still isn’t a great long distance saddle. You’re going to be much better off using the Romin saddle if you want a similar fit for anything longer than 70-80 miles of riding. The overall design of the saddle is perfect for allowing you to put down the power. The shape of the saddle in the rear is more flat, and the middle cutout makes it ideal for any type of riding, road, gravel or mountain. The shorter nose allows for more aggressive positioning when needed although you should note that you will likely need to make some fore and aft adjustments to your regular saddle position by comparison. Between this saddle and the Power Arc saddle, if you’re on the hunt for a new seat, I firmly believe that you’ll find a great fit on one or the other of the two after trying both.

I was pointed to this saddle by a bike fitter from the standard power saddle. This worked for me. The "wings" don't flare out as much as the standard power saddle. This worked for me much better. Similar fit and cushion as the power saddle but with narrower "wing". I have one of these on each of my bikes.

The Power saddle for Romin users

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.
