Overview
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.

FAQ
Good questions
Get to know Factor
There's more to Factor than this one product. Our Factor page has the full Factor lineup we carry and more about the brand.
Visit the Factor page →Will this seatpost work with other Factor frames?
No. This is a frame-specific component designed exclusively for the Factor Ostro VAM. It will not fit other Factor models due to proprietary seat tube geometry and clamp interface.
What does 0mm setback mean for my fit?
0mm setback positions the saddle directly above the clamp axis. This typically suits riders with a forward riding position, shorter torsos, or those whose bike fit places them over or ahead of the bottom bracket.
Is the Ostro VAM seatpost UCI legal?
Yes. Factor engineered the Ostro VAM seatpost to comply with current UCI aero regulations, so it can be raced at any UCI-sanctioned event without modification.
