After riding 25 miles or so, I still get the numbing sensation going on and am concerned about damage. Two years ago, I did a metric century on a WTB seat and had some numbness for a few months afterwards...not good. I ran across this company...http://www.ismseat.com/adamo_saddle.htm and would like to get some feedback from users. I currently have a Specialized Avatar that seems to work well for shorter distances, but after a few hours riding, the numbness thing starts again. Opinions on this item or another model called the Spiderflex would be great. Thanks to all!
