Welcome to TE web site. First of all, please get yourself put back together. Injuries are no fun.

Now that you mention about questions?? sure I have a question I see lots of kids on BMX bikes and their seat is literally pointing straight up. What's up with that??

I'm a strict roadie no cyclocross nor mtn bike so I'm really ignorant about lots of things. the seat pointing straight up is one thing I'm totally confused. Why not just wrap some foam around the top of the seat tube with duct tape??
