KEY FEATURES
AERODYNAMICS MEETS LIGHTWEIGHT PERFORMANCE
Optimized Aero Tube Shapes – Mid-chord aero profiles inspired by NACA airfoil designs, carefully truncated to enhance stiffness, weight reduction, and crosswind stability.
Wide Stance Fork with Reversing Flow Energising Channel – Addresses airflow interaction between the wheel, tire, and fork, reducing turbulence and improving aerodynamics.
Fully Integrated Aero Cockpit – The Black Inc Barstem ensures clean airflow and reduced drag, while maintaining a 1⅛” top headset bearing for optimized frontal area.
Super Lightweight Frame – Weighing just 780g (size 54, painted), the OSTRO VAM is one of the lightest aero disc frames on the market, easily building to the UCI weight limit of 6.8kg with a power meter and aero wheels.
DESIGNED FOR SPEED & COMFORT
32mm Tire Clearance – An aero race bike with unmatched versatility, handling cobbles, rough roads, and long-distance endurance rides with ease.
ViSTA-Style Seat Stays – Ultra-thin pencil seat stays absorb road vibrations and bumps, offering superior comfort without sacrificing aerodynamics.
Advanced Carbon Layup – Proprietary carbon fiber construction ensures a high level of compliance, balancing smooth ride quality with world-class power transfer.
PRECISION GEOMETRY & FIT
Optimized Handling Geometry – Virtually identical to Factor’s O2 and O2 VAM, with linear stack & reach progression for a perfectly balanced ride.
Adjustable Seatpost Options – New mid-depth profile, lightweight seatpost, available in 0mm and 25mm offset.
Modular Cockpit Compatibility – The OSTRO VAM supports both the Black Inc Barstem (fully internal cables) and separate bar/stem combinations.
SYSTEM DETAILS & CUTTING-EDGE DESIGN
Electronic Shifting Only – Built exclusively for electronic groupsets, reducing weight and drag.
T47 Threaded Bottom Bracket – Ensures secure fitment and easy maintenance, a first for Factor.
Three Different Fork Offsets – Provides optimized handling for every frame size, ensuring the perfect ride experience for all riders.
THE NAME BEHIND THE PERFORMANCE
The OSTRO is named after one of the eight principal Mediterranean winds, a southerly force that sweeps through the Côte d’Azur. This wind mirrors the essence of the OSTRO VAM—a bike built for the fast coastal roads and high-altitude climbs of the Tour de France, offering both aerodynamic supremacy and super-lightweight agility.
