This is an excellent Koobi Classic gel SI bike seat saddle. I tried for a short time. No crashes, rubs, etc but does have a small hole down in the groove. Hardly used this seat so something must have dropped on it. Easily repaired with black silicone or touch up with a Sharpie since it is in a non-contact area. I will leave as-is.  FECAlloy rails.
