As far as I know I put on the first DH races anywhere in the world. We just celebrated the 40th anniversary of the first race, conducted on modified 40-year old Schwinns.
Later, my friend Gary Fisher and I rented a garage to build bikes in. We called our company MountainBikes, but we didn’t protect that name very well with a trademark
Now the sport has come so far that even on my modern full suspension bike, my skill set is not sufficient just to ride top to bottom on a downhill course.
