Someone in here recommended a Cloud 9 seat. I bought one. It squeaks and creaks with every pedal stroke. Loudly, like something is broken. Plus, there is no way to adjust it so it is comfortable. I could just as well burned the $30 and rolled down a flight of wooden steps. i am going to remove it and examine it, but I will probably be reinstalling the old supposedly harder seat that gives more comfort, and doesn't make a lot of noise. Coud 9 is a pain in the butt!
