Factor Ostro Vam Force E1 170 ARC 1400 Road Bike

The Factor OSTRO VAM is a premium all-around aero road bike engineered for riders who demand uncompromising speed, efficiency, and lightweight performance. Designed using advanced aerodynamic principles and race-proven technology, the OSTRO VAM delivers exceptional responsiveness on climbs, sprints, and flat-out efforts alike. Combining a lightweight carbon frame with aerodynamic tube shaping, it offers the perfect balance of stiffness, comfort, and handling for competitive racing and high-performance road riding. This build features the latest SRAM Force AXS E1 wireless electronic groupset paired with DT Swiss ARC 1400 carbon wheels, providing precise shifting, outstanding power transfer, and aerodynamic efficiency.

Engineered For Speed
The goal was to create the lightest aero-oriented bike in the pro peloton. The OSTRO VAM is a bike that can be competitive on any terrain. It is ready to win sprints, conquer cobbled classics, and summit the climbs with the best.

Super-Thin Aero Seatpost
The seatpost is a slender 15mm in width, capitalising on the latest UCI rules. Its profile is the result of an intensive study of its interaction with the chaotic airflow from the rider’s legs and a tireless R&D process. First, incremental iterations were simulated, then rapid prototypes of the best shapes were wind tunnel tested to arrive at the best performing. The thin new seatpost is made possible by relocating the Shimano Di2 battery housing inside the seat tube and mounting it from behind the bottom bracket. 

Aero Integrated Bottle Cages
The OSTRO VAM comes with innovative bottle cages which are location-specific and integrated into the frame’s aerodynamics. The downtube cage acts to direct airflow from the downtube over a bottle, neutralising the drag of adding a bottle to the bike. The seat-tube cage works to reattach airflow to the seat-tube, and it’s so effective that the bike is faster with the cage mounted and no bottle than with no cage at all.

Ultralight Seatpost Clamp
The new pusher-type seatpost clamp is repositioned at the rear of the seat-tube, where it distributes force over a large area to give a very secure fixation with a low torque, allowing a very lightweight clamp and a dramatic reduction in seat-tube width.

Ceramicspeed T47A BB
The T47 standard for threaded bottom brackets ensures a secure fit, easy maintenance, and contributes to exceptional power transfer. Fast-spinning Ceramicspeed bearings ensure ultimate efficiency.

Revised Rider Positioning
In response to the analysis of customer and pro athlete position data, two key changes have been made. First, a 45cm frame has been added to the range. Second, the seat-tube angle is 0.5º steeper.

Black Inc Integrated Aero Barstem
The barstem is the benchmark aero cockpit, combining leading aerodynamics with refined ergonomics and a feathery weight. Its highly developed shape, with drops flared by 30mm, boosts control and significantly reduces the drag of the combined bike and ride.

MASTERS OF CARBON
The new OSTRO VAM is a sub-7kg aero weapon, so your crit bike is also your mountainous gran fondo bike, and they’re both awesome. This lightness also means that the pros can use their most aero option more of the time (and for big mountain stages with summit finishes, we make the feathery and fast O2 VAM).

CONFIDENCE BUILT IN
We can measure and test many things, but not the level of confidence that a bike gives you. It’s a feeling. Building it into a bike is where art meets science, and where our design team’s decades of engineering combine with their decades of riding. The perfectly balanced handling geometry of the new OSTRO VAM – combining cat-like agility with unflappable high-speed stability and on-rails cornering – is carried over from its predecessor, which was loved by pros, customers, and reviewers alike. Greater compliance adds to both the feeling of confidence and comfort over long rides.
