Factor O2 Custom Bike Build
However, limiting its capabilities to only climbing would be a crime. It can sail around corners, go for long distances, and has made appearances on the podium of the Tour de France and Paris Roubaix
Every tube and section of the O2 has been engineered and developed for a ProTour level quality ride: maximum power transfer under load, but also vibration dampening to feel fresh after a 6 hour ride.
The O2 does all that in style, with a slender profile that will subtly stand out in any group ride. Elegance, all-day comfort and high performance coming together.
Build your dream bike with us and choose from a broad selection of group set options, wheels and components. We’ll build your dream bike at Factor Bikes UK and invite you for a complimentary bike fit and bike test. Contact us to get started.
