Inspired particularly by the scarab beetle’s iridescent shell, the Factor OSTRO VAM Scarab uses iridescent paint pigmentation to accentuate the hyper-performance you’ll enjoy on every ride.

Using an anti-absorbent pigment that reflects the light results in a prism effect. As you move around the frame, you see the light hit the frame and reflect at different angles as you move, creating a different color tone.

The effect makes the frame beautiful enough to hang on a gallery wall, but that would be a waste considering the OSTRO VAM is the lightest aero bike on the planet. It’ll inspire you to get out there and ride!

A pure racing machine

The OSTRO VAM is engineered for peak performance, combining lightweight construction with exceptional aerodynamic efficiency. Utilising our premium carbon frame, this bike excels in both climbing and flat terrains, ensuring the ultimate performance in all road situations. The integration of the Black Inc. Barstem enhances its aero profile, while the CeramicSpeed SLT Bearings ensure smooth and effortless maintenance. Every aspect of the bike is designed to optimise speed and agility, making it ideal for competitive racing.
