The new 15mm seatpost pushes the limits of UCI rules, shaped by relentless R&D and aerodynamic testing. After hundreds of sim and wind tunnel trials, the result is a design that slices through turbulent airflow from the rider’s legs. By moving the Di2 battery into the seat-tube, there's no need to remove the post—protecting fit, preventing slippage, and keeping you dialled.

The OSTRO VAM’s bottle cages are aero weapons. Frame-specific and wind-cheating, the downtube cage channels air over the bottle, while the seat-tube cage actually makes the bike faster—even with no bottle. Perfect for high-speed race finales. Up front, the barstem sets the aero standard. Featherlight, perfectly shaped, and flared 30mm at the drops, it slices through wind and delivers unbeatable control.

The new OSTRO VAM is a sub-7kg aero missile—light enough for big climbs, stiff enough for crit attacks. It’s the one bike that does it all, and does it fast. More aero, more stiffness, more lightness—once thought impossible, now brought together through relentless carbon lay-up tuning, elite materials, and full control of our own factory. The result? A ride that’s nothing short of revolutionary.
