I recently installed a Terry Fly saddle, and I noticed it making a cracking, rubbing sound, after 30 miles of my 50 mile loop, yesterday. I was able to duplicate the sound by pressing firmly down, in the center of the saddle. Upon doing so, the underside of the saddle rubbed against the top of the seat post clamp, therefore making the annoying sound. The edges of the saddle cutout, underneath, rub on the squared sides of the post clamp. Anyone else experience this? If so, what did you do to fix it? I was thinking of using wax, to lube the seat post clamp, to prevent the friction. At the same time, I'm afraid that the squared shape of the seat post clamp will eventually wear into the bottom of the saddle. I was thinking of grinding the square edges of the post clamp, to hopefully prevent this. BTW, I weigh 175 lbs, so weight shouldn't be an issue. Any ideas or suggestions?

Thanks, Mike
