I went to the San Diego River today to ride my MOUNTAIN bike… (NOT Bmx) and I had a certain event. At the end of it near a library there was a staircase. I hadn't gone, not jumped, down a staircase with my bike for years... So I decided to. Although.. I forgot how to do it, and just sat down, and rode slowly.GUESS WUT HAPPENED.Being a mountain bike, the seat has almost no padding. (because when mountain biking you don't sit down)Anyway, I started going down. Then the rest happened. It crunched "something special" about 7 times. I haven't checked the brakes in forever so I couldn't stop. The bike has dual suspension so it added more pop. Anyway, it hurt an I decided to not sit down on my bike the rest of the day. lolThere was a grass hill/ramp right next to it so I went down that afterward finding it to be less crunchy... (awesome)Anyway discuss about stuff you did on your bike like crashes or "crunchies".
