Expanding on the success of Specialized's original Power saddle, the Power Arc Expert is designed to surpass its predecessor. How? To reduce numbness, pressure, and pain on unwanted areas, Specialized made the Arc Expert's shell with wider, elongated Body Geometry features, ample padding with Level Two PU padding, and shorting the nose a bit. Proven through blood flow testing and pressure mapping, these improvements make a huge impact for comfort - regardless of how much time you want to put in on this saddle. The rails have the same channel, lengths, and hollow titanium rails as the original Pro Arc. Beyond that, there is a curved shape Body Geometry to make you feel as if you're "in the saddle," not on it. Ultimately this creates better performance in all seated positions, whether you're a man or a woman. 

Features:

  • Lightweight and supportive PU padding for comfort and support on longer rides
  • Lightweight, durable, and hollow titanium rails
  • Level 2 padding: Medium density foam for bike feel with additional cushioning
  • SWAT™-compatible mounts molded into the saddle base allow for integrated storage solutions

Specialized Power Arc Expert Saddle (Black) (Titanium Rails) (143mm)
So far so good. Been for several rides now and no more problems with numbness. As hard as and smaller than my previous saddle, but pressure better distributed. Also lighter than previous saddle.

Finally found the saddle that works for me! Other short nose saddles were ok. Other cutout saddles were ok. The curve of this one just fits.

Specialized Power Arc Expert Saddle (Black) (Titanium Rails) (143mm)
I decided to upgrade to this saddle when my Power Expert broke. I think I finally found the perfect seat for my narrow ass. Super comfortable, with absolutely no rubbing on my inner thighs and no pressure on my manly area even in the drops. The YouTube review I found comparing the two described it accurately: the Power Expert was like sitting on a flat plank and this is like sitting on a round log. Super happy with this saddle. It's perfect.

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.
