Road Competition

Road racing bicycles have eighteen switchable gears.
Since road racing bicycles are ridden over long distances between 200 and 300 km, their brake and gear installation is sanctioned, and they use quick release hubs that can be removed in a single operation, making it easy to replace wheels while out on the road.

Velodrome

The track surface is made of asphalt and the course itself consists of corners and straight sections. There are 333 m, 400 m, and 500 m tracks, but the world standard is 250 m.

  • Anti-slip pavement
    The surfaces of the uptrack and warmup track are treated to prevent slipping.
  • Asphalt track
    Multiple layer construction designed with hardness, durability, and water absorbtivity in mind. First a layer of earth, crushed rocks, or soil cement is laid down, and then this is covered with a number of asphalt layers. Finally, after some trial runs, the surface is finished with a special asphalt.
  • Banks
    The major feature of the track is its banks that slope up and down. Both center sections of the track have the highest slope among all other sections.
  • Lines and guides
    The lines and guides on the track surface are made of non-slip materials.
  • Sprinter's line
    A continuous red line painted 90 cm from the inside edge of the track.
  • Blue band
    Blue band around entire inner edge of the track for mounting bicycles to make it easier to start.
  • Safety zone
    The surface 3.5 m in the direction of the center of the velodrome from the blue line is covered in soft material such a grass turf so that racers do not injure themselves if they fall off their bicycles.
  • Infield
    The area enclosed by the velodrome where racers can change and warmup.
  • Center portions of track (2)
    500 m track: 17° to 29°
    400 m track: 27° to 34°
    333 m track: 30° to 35°
