Factor Bikes Monza Ultegra DI2 (Order to your Spec)

Race Sunday, Train Monday

Not all racers are pros. Across the world, passionate competitors balance family, careers, and life’s responsibilities while still pushing themselves to their limits on the bike. Their "World Championships" happen at local crits, club races, fast group rides, and solo breakaways at dawn. They commute to work, train in the dark, race on weekends, and push for personal bests whenever they ride. The MONZA is built for those who want to win on Sunday and train on Monday. It’s a true high-performance race bike that balances speed, efficiency, and real-world usability, without unnecessary complexity. The Factor MONZA is not a step down—it’s a step in the right direction. Choose  bars and stem sizing to order. 

In-frame storage

With the ability to fit two tubes, two CO2 cartridges, and a patch kit, the MONZA’s in-frame storage eliminates the need for a saddle bag which will save up to six watts of drag. On-the-bike self-sufficiency no longer needs to come at the expense of aerodynamics or sleek appearance.
