Koobi SI Classic Gel...OUCH!
I purchased the Koobi SI after reading some very good reviews here, but unfortunately this wasn't the saddle for me. It felt o.k. the first few rides, but gradually began to give me such pain in my sitbones that my butt hurt when I sneezed! And this wasn't sneezing on the bike. This was lying on my side, on the couch, trying to give my butt a rest, and sneezing, and still feeling it in my sore butt! I was in agony after my last ride and am sending it back. I just purchased a Terry Butterfly Ti and Liberator Ti Race and am hoping one of these will be better. I just attached the Butterfly yesterday and feels good upon first sit. Time will tell.
I'm a new rider and now I really see what an individual thing saddle comfort is.
