i hate these when they are in the mound shape.... i was coming down a hill at 39kmph according to my computer.... turn and suddenly wham there it is 1 metre high.... now i know how a rat feels when you kick it through the air....
my bike just flew over it for about 5 metres.... carrying me with it... my one feet detached itself from the clip(really need to tighten it)
then it continued down the hill with me hopping alongside it on the left and my right foot still clipped in..... ran through a couple of thorn bushes..... man my legs were sore.... and also i was standing when my bike hit the ramp and slammed into me propelling me upwards from an uncomfortable point
