Ridea Aero chainring is aerodynamically designed to minimize drag. When used with the Ridea Track 3D Track crank: the aero spider design and chainring creates a sealed surface to reinforce stiffness and improve aerodynamics. Otherwise its a damn stiff and solid chainring for use with any 144mm BCD.
