Integrated Aero Barstem – The New Reference for Aerodynamics on Road and Gravel
The Integrated Aero Barstem is the ultimate cockpit for road and gravel cycling, designed to offer maximum aerodynamics, advanced ergonomics, and ultra-lightweight. Thanks to its innovative shape with 30mm flare in the drops, it improves control and significantly reduces air resistance, while simultaneously increasing comfort and wrist freedom of movement.
This component is designed to elevate the performance of the OSTRO VAM to the levels of the fastest bikes in the world, with the direct contribution of seven-time Grand Tour winner, Chris Froome.
Competition Aerodynamics
The Integrated Aero Barstem optimizes speed in two ways:
-
More aerodynamic position – The reduction in lever width allows for a more compact and faster position, minimizing the frontal area.
-
Optimal air penetration – The 40mm profile design has been tested with CFD (Computational Fluid Dynamics) and wind tunnel to ensure superior performance compared to the competition.
- The advanced shape of the upper limbs allows for maintaining a stable and comfortable position, both on the road and on rough terrain.
Ergonomics and Comfort at the Highest Level
The Integrated Aero Barstem is designed to provide maximum safety and comfort:
-
3° sweepback on the upper parts for a more natural wrist angle.
-
7° drop with flare (29mm wider than the levers) for better control, both on road and off-road.
-
Upper radius of the narrower drop to bring the brake lever closer by 5mm, making it easier to use with the new Shimano and SRAM groups.
-
Compact shape and mid-depth profile for optimal grip even on climbs.
Perfect Compatibility for Road and Gravel
Thanks to the 7° angle in the drops, the barstem is ideal for both road bikes and gravel:
-
On the road: choose the width based on the drops to achieve a more aerodynamic position on the levers.
-
On gravel: choose the width based on the levers for greater stability on the most challenging descents.
