I saw this over on the Team Bonney Lake Bicycle site.
London welcomed the Red Bull Mini Drome to York Hall, where over 1000 spectators gathered to get a taster of the world's smallest velodrome in action.
Fixed gear riders from across the UK tried to hold on to the red line as they rode around the track aiming for the fastest time.
The purpose built track has been engineered in Germany by Velotrack, the team that built the velodromes for the Atlanta Olympics and the Delhi Commonwealth Games. The Red Bull Mini Drome track will maintain race-worthy dimensions in the smallest possible size to enable a single pursuit.
