I have had this on rides over 25 miles since the beginning. I have tried every kind/shape of saddle and bike short to no avail. My chafing is just under the butt cheek in a fairly small area, so I finally just resorted to using either Nu-skin (liquid bandaid) or a heavy duty band aid to cover that spot. Not ideal, but it does the trick. Hope you have better luck in finding a saddle that doesn't chafe.
