Following another couple of bad injuries (Stead and Holder) I think something must now be done about the speed of the bikes. I know that it's called SPEEDway but I think that bikes are becoming to fast for the riders reaction time.Tracks haven't improved to match the bikes, O.K. we now have air fences but in my opinion riders have a false sense of security. Following spectacular crashes we hear "If we didn't have an air fence that would have been a serious injury" Well if we didn't have an air fence maybe riders wouldn't ride on the edge of what is safe and what is madness.
