    Built for riders chasing podiums—from local crits to solo breakaways.

    Purposeful Design

    The MONZA takes the essence of the OSTRO VAM and refines it for broader accessibility. It’s made for competitors who want performance without the fuss, at any level of the sport.

    All-Road Ready

    MONZA accommodates tyres up to 34mm, offering better comfort and fewer punctures across varied terrain. It’s built for racers, commuters, and year-round riders tackling every road and every weather condition.

    Integrated Storage

    MONZA’s in-frame storage fits two tubes, two CO₂ cartridges, and a patch kit—no saddle bag needed. It cuts up to six watts of drag, delivering self-sufficiency without compromising aerodynamics or clean aesthetics.
