Factor OSTRO VAM L39ION Edition – Aerodynamics, style, and identity for high-speed criteriums
The Factor OSTRO VAM L39ION Edition is more than a racing bike: it is a manifesto of speed, urban culture, and competitive spirit. Born from the collaboration between Factor Bikes, Justin Williams, and his team L39ION of Los Angeles, this special edition of the OSTRO VAM celebrates the essence of the American crit scene, with a design inspired by the urban transit lines of Los Angeles and geometry designed to dominate high-intensity criteriums.
A tribute to Los Angeles and L39ION culture
Raised in South Central LA, Justin and Cory Williams turned their passion for cycling into an inclusive and innovative movement. The OSTRO VAM L39ION design recalls the city bus lines, a symbol of connection between neighborhoods and a metaphor for the role the L39ION team plays in uniting cyclists, communities, and cultures.
