Factor 2026 Ostro Vam Sram Red British Racing Green 56

Thanks to our engineers' expert carbon fibre lay-up techniques, our commitment to premium materials, and the unique control our own factory offers, the new OSTRO VAM performs in all areas. This isn't just innovation; it's a reimagining of performance on two wheels, all designed to deliver an unmatched cycling experience.

NUMBERS DON'T LIE

Experience the new OSTRO VAM: lighter, faster, unbeatable. Now 250 grams lighter and 7 watts quicker with optimized Black Inc 48|58 wheels, it redefines responsive riding with unparalleled aerodynamic efficiency. Journey through our OSTRO VAM Launchbook as we guide you using the latest computer modelling tools to unlock aero performance gains that had been unthinkable.

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.

The seatpost is a slender 15mm in width, capitalizing 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 sim tested, 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 mounted from behind the bottom bracket. This has the added benefit of avoiding seatpost removal for battery access, which reduces the risk mis-adjustment leading to incorrect height, slippage or damage from over-tightening.

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, making it perfect for the finale of pro races when the second bottle has been discarded.
