This isn't a big deal since it doesn't really affect my overall riding experience, but when I do a lot of moving around in the saddle, I notice a popping noise, not always but sometimes, when I move of the narrow tank wrap into the pocket, like it's coming from under the seat where the base hooks. Seat is never loose, or feels like it's trying to come off, but it can be un-nerving. This occurred before the Sargent conversion and continues to do so. Has anyone else experienced this and is there reason for concern that I'm not aware of? Do I need to start thinking about a parachute? Is there a secret eject feature I'm not privvy to?
