Just come back from riding with a friend. Unfortuanately he took a rather heavy fall (nothing broken). I was sat at the end of a long straight on the track watching him come towards me. The track conditionds were good. He was travelling straight at high speed when the front wheel just washed out from under him. This resulted in him and the bike tumbling down the remainder of the straight. He weigh approx 90 kilo's. Is this a problem with the bike and suspension set. What can he do to avoid a similar incident.
