“At the Sydney Olympic Games, Brett Aitken and I had the confidence of knowing we had the best bikes on the velodrome,” said McGrory. “After the 2000 Sydney Olympic Games, we were fortunate to have been gifted our gold medal winning BTs that in my mind sit along with the medals themselves as a symbol of our greatest success.”
Reading between the lines, but that quote tells me Aus. thinks that BT hasn't kept up in terms of design/engineering. Not really a surprising thought, given BT hasn't really updated its design in years.
