Description
Factor MONZA Ultegra Road Bike
Every part of the MONZA Road Bike reflects Factor’s deep understanding of riders’ needs. Smart integration for lights, radar, and storage keeps your setup streamlined and aerodynamic, while the HB04 Black Inc Barstem delivers comfort and precision handling with a clean, adaptable cockpit. Factor has made maintenance effortless, with practical design touches such as a round steerer tube, T47 bottom bracket, and seatpost battery space for modern electronic drivetrains. It’s thoughtful engineering that empowers riders to focus on performance – not on upkeep.
Pure Race Pedigree, Real-World Practicality
The Factor MONZA isn’t a compromise – it’s a refined evolution of Factor’s legendary race engineering. Drawing inspiration from the OSTRO VAM, the MONZA delivers elite-level aerodynamics, stiffness, and handling, but in a more accessible and versatile package. This is a true high-performance race bike for real riders: those who train hard, race harder, and expect their bike to keep up with both. Every detail serves a purpose, striking the perfect balance between speed, simplicity, and reliability.
Utility-Driven Design, Performance at Its Core
Built for those who ride in all conditions and for every reason, the MONZA seamlessly integrates practical features without compromising performance. With WorldTour-level stiffness and aerodynamics, the bike remains razor-sharp in a sprint or on a climb, yet adds convenience through integrated lighting options and in-frame storage for tools and essentials. Its geometry has been fine-tuned to support longer days in the saddle, offering a slightly higher stack height for improved comfort and open hip angles – ideal for both training and racing.
Future-Proofed for Every Ride Ahead
The MONZA is designed not just for today’s challenges, but for the future of performance cycling. Featuring clean cable integration, UDH compatibility, and clearance for up to 34mm tyres, it’s built to handle rough roads, race circuits, and everything in between. Wider tubeless tyres ensure a smoother, faster ride across mixed surfaces, while the UDH (Universal Derailleur Hanger) ensures long-term adaptability with emerging drivetrain technologies. The result? A bike that’s as ready for tomorrow as it is for your next race.
