Specialized S-Works Power Saddle (Charcoal) (Carbon Rails) (143mm)
Saddle is extremely light and very comfortable. Would definitely recommend!

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.
