I was going to edit my post to say that im not trying to be a jerk just cant picture it happening. My point I guess is how can a seat pop with enough force to strike you and you be quick enough to catch it behind you when riding. Dont get mad, just read what you said. You cant teach me anything about riding, but maybe you can teach me some of those ninja skills.
Joke. Calm down. Take a deep breath. Ok, now reply.
