The Specialized Phenom Comp is a mountain bike saddle you can rely on during long days of shredding trail.  It's designed with both comfort and strength in mind. Just like the Pro and Expert Phenom versions, it has the Adaptive Edge base construction which allows flexibility in the carbon reinforced shell, to give an almost custom fit feel and reduce chafing as you pedal. The rounded anti snag tail, and low friction panels fore and aft, help you migrate on and off the saddle with ease. The Level 2 padding is lightweight and supportive, for that just right feel without being bulky. Patented Body Geometry Design allows blood flow to sensitive arteries. The Phenom Comp however, unlike its counterparts, has super durable hollow chromoly rails for peace of mind. It will take a beating on the trail, but not on your wallet. SWAT compatible mounts molded into the saddle base allow for sleek and integrated storage solutions. 


  • Patented Body Geometry Design is lab tested to assure blood flow to sensitive arteries.
  • Lightweight and supportive PU foam for comfort and support on longer rides.
  • Low friction panels on the nose and tail improve pedaling efficiency and mobility while moving ‘on and off’ the saddle.
  • Carbon-reinforced shell with Adaptive Edge technology adapts to your body for a near-custom fit and all-day comfort.
  • Light and super-durable, hollow chromoly rails.
  • SWAT compatible mounts molded into the saddle base.
  • Level 2 padding: Medium density foam for bike feel with additional cushioning.

Specialized Phenom Comp Saddle (Black) (Chromoly Rails) (143mm)
This saddle is well-made, and I liked the narrow nose, which avoided chafing on my inner thighs. However, I found the padding insufficient for a 68 mile road ride that left my sitz bones feeling bruised and chafed. I plan to exchange it for a Bridge Comp w/ MIMIC, which I hope will suit me better.

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.
