High Quality Content by WIKIPEDIA articles! A velodrome is an arena for track cycling. Modern velodromes feature steeply banked oval tracks, consisting of two 180-degree circular bends connected by two straights. The straights transition to the circular turn through a moderate easement curve.Banking in the turns, called superelevation, allows riders to keep their bikes relatively perpendicular to the surface while riding at speed. When traveling through the turns at racing speed, which may exceed 85 km/h (about 52 mph), the banking attempts to match the natural lean of a bicycle moving through that curve. Therefore, the centripetal acceleration of the combined inertia of bicycle and rider moving in the curved path balances the tangential acceleration pulling them outwards. There is no centrifugal effect 'trying' to tilt the bicycle outward: the net normal force is acting on the tires through the riding surface.
