Cinelli Vigorelli Shark Track Frameset
From the manufacturer:
The legacy of Vigorelli returns where it all began, without compromise: the Velodrome. The most used fixed gear frame inflates the muscles with a hyper-aggressive track geometry, sharpened like a Laser. The 1/8 "track steering tube, the short rear triangle, the super-rigid rear wheels. In the Red Alert color with holographic details, the Vigorelli Shark is ready to devour any track.
