Factor Ostro VAM Seatpost - 0mm Setback | Chrome

What Makes the Ostro VAM Seatpost So Aerodynamic?

The Factor Ostro VAM Seatpost is engineered exclusively for the OSTRO VAM frame, featuring an ultra-slim aero carbon profile that slices through the turbulent airflow generated by the rider's legs. Factor designed this post to capitalize on the latest UCI aero regulations, allowing the seat tube and seatpost junction to be fully optimized without sacrificing structural integrity or ride compliance. The 0mm setback variant positions the saddle directly over the clamp axis, ideal for riders with a forward position or those with longer femur-to-torso ratios.

Built from high-modulus carbon fiber and finished in a chrome colorway that pairs with Ostro VAM frame options, this is a frame-specific component designed to complete the bike's integrated aerodynamic system from headtube to seat cluster. The proprietary clamping system ensures proper load transfer and frame protection, maintaining the OSTRO VAM's UCI-approved aero profile from every angle. This is not a universal seatpost; it exists to make the Ostro VAM faster.
