From the Specialized site:
If your sit bones are between 100 & 130mm, you should ride a 143mm, unless you ride in a very upright, comfort position. Then you should ride a 155
I too had my sits bones measured at a Specialized dealer and according to the number off the ass-o-meter, the Salesman said I needed a 143, so I purchased an Avatar Expert in 143 @ $110. At 55 years of age, I'm not that flexible and ride a little upright on a drop bar road bike. After a number of rides of 50+ miles and hard intervals, I never felt totally comfortable on the saddle. I believe most of my problem is this saddles contour with the slope towards the middle and off the sides, I was always moving or slipping one way or another, like falling off the edge.
That's when I read about wider and flatter saddles on another forum with several people recommending the Specialized Toupe or Romin saddles in size 155. In my eyes, the Romin has the same slope as an Avatar with less padding. The Toupe is flatter in the sit bone area with limited padding. So when the dealer had an store wide anniversary sale at 45% percent off, I purchased a Toupe in 155. First impressions were really good with the extra width and the flatness of the saddle. I really enjoy the fit of this saddle. But.....I also missed the extra padding of the Avatar for rides over 50 miles. Perhaps if I wasn't so cheap and paid more then $30 for bibs with better quality chamois the Toupe would be perfect.
Bottom line, consider what's posted in the quote above from Specialized.
