The reason I ask about crash bars, is because I had a spill last week. was only doing 5 to 10 mph, coming up too a junction on a bend went over a drain cover, covered with loose chipping and lost the front wheel. I managed to break 2 ribs but my better half snapped her left leg below the knee and the knee itself is in about 12 pieces, required a 5 1/2 hour operation and a lot of metal work inserted.
