Luck for me I never experianced any problems like this so can't coment on that.
But just wanted to X2 the Terry saddle. We just started riding the rail trail this spring. I picked up a used cypress with the stock saddle. I was experianceing numbness in the private area and a sore butt no matter how I adjusted it. Put a Terry Liberator Y Pro Gel on and that is all gone. It does everything they claim on thier website. It's very firm with just a thin gel layer for the sit bones. I feel I could go all day on it and the cypress is a very upright position.
