Fixie / Track bike

TSUNAMI track bicycle or track bike is a bicycle optimized for racing at a velodrome or outdoor track.
TSUNAMI track frame is specific to its intended use, with emphasis on rigidity and lightness.
TSUNAMI frames for sprinting seek to maximize rigidity, while those for general racing seek to reduce aerodynamic drag.
The dropouts or track ends face rearwards to facilitate chain tension adjustment. A true track fork, unless aerodynamics are the primary consideration, has round-section blades for greater lateral stiffness when sprinting.
