Factor OSTRO VAM Seatpost

Factor OSTRO VAM Seatpost

The Factor OSTRO VAM Seatpost is built for efficiency, pairing a lightweight carbon fiber construction with an aero-optimized profile refined in the wind tunnel. Its slender shape cuts through the air, while a one-bolt clamp makes saddle tilt adjustments quick and precise. Compatible with 7×9 mm saddle rails, it’s available in a 350 mm length with 0 mm or 20 mm setback options. This post is a direct replacement for the latest-generation OSTRO VAM, but it is not compatible with the earlier OSTRO VAM V1.
