I’ve been using the ISM Saddle for 2 years now and have a Typhoon on my Specialized Roubaix and my Trek hybrid. The saddle is awesome! After trying 3 other brands of high end road saddles, I took a chance on the ISM, and wow!! No numbness of any kind, can sit for a century with ease. I rode last week in the CASA River Century and asked my riding buddy whom I have encouraged to try the ISM after 30 minutes, I asked him if he was numb… his response was yes… I told him, that I was not… and so this continued for the entire ride… no pain! It did take a while to get used to… and to get adjusted properly… and now it kinda’ feels like I’m sitting on a marshmallow… well, maybe not… but it sure don’t hurt!!!
