Taking its name from one of the world’s most iconic racing circuits, the MONZA is built on the industry-leading engineering of the OSTRO VAM to deliver raw performance and relentless speed to the everyday racer. The MONZA is a true high-performance race bike that balances speed, efficiency, and real-world usability while retaining Factor’s racing DNA.

Drawing on the developmental DNA of the OSTRO VAM - independently tested as the world’s fastest road bike and proven in World Tour victories with Israel Premier Tech - the MONZA carries this racing pedigree forward in a refined and streamlined package.

The MONZA retains an aero-optimised frame, tuned for efficiency in real-world
racing conditions while refining certain features and materials to reduce
manufacturing complexity and costs. Similar to the OSTRO VAM, the MONZA utilises an integrated and aero-optimised front end that has been meticulously designed to promote flow attachment and reduce drag.

However, unlike Factor’s flagship all-round road machine, the MONZA features a planar break between the fork and frame. This approach enables Factor to deliver refined elite-level performance to a wider cycling audience.

The MONZA’s design leverages the OSTRO VAM’s proven technology with a more streamlined approach. The head tube and fork feature converging contours, while the top tube, seat stays, and chain stays have smaller-profiled tube sections with tighter, more refined lines—enhancing both aerodynamics and manufacturing efficiency.

A strategic carbon layup reduces cost while maintaining Factor’s signature ride feel. The MONZA’s balanced stiffness-to-weight ratio ensures explosive power transfer and efficiency at high speeds.

With an ambition to deliver handling identical to Factor’s WorldTour race bikes, the slightly democratised fit features an increased stack height by 10 mm. This allows for a broader range of rider flexibility and comfort without sacrificing performance. Retaining the responsive ride feel Factor racers demand, the head-tube angle and fork offset are identical to the OSTRO VAM. The short chain stay lengths and wheelbase are also the same, tuned for both fast-moving pelotons and solo rides.

An all-new HB04 integrated, semi-aero barstem features optimised hand positioning and moulded cable entry ports. This reduces machining complexities and facilitates easy cable routing while offering a clean, simplified front end.

Retaining an aero-first design, the MONZA's head-tube assembly prioritises a pragmatic approach with a simpler round steerer than the OSTRO VAM’s, paired with a larger 1.5" bearing. This allows for more straightforward internal cable routing for cyclists to set up and adjust their position.

Integrated in-frame storage, inspired by the SLiCK, features a convenient latch
mechanism for easy access to ride essentials—without compromising aerodynamics. This design saves up to six watts of drag while lowering the centre of gravity. With 34 mm tire clearance, the MONZA hits the sweet spot between aerodynamics and versatility, ensuring optimal performance in real-world conditions.

MONZA is not a compromise; it is Factor’s vision of performance, redefined for the modern racer, tuned for efficiency.
