Factor OSTRO VAM Seatpost
The Factor OSTRO VAM Seatpost is made to be lightweight and is shaped to improve aerodynamics. This seatpost was designed in a wind tunnel and uses a slender shape to cut through the air. Made from carbon fiber, this seatpost is lightweight and uses clamps for 7×9 mm saddle rails. Additionally, it uses a one-bolt saddle clamp that makes it exceptionally easy to adjust your saddle tilt. This post is available in a 350 mm length and 0 mm or 20 mm setback options. It is a direct replacement for the latest generation OSTRO VAM, but is not compatible with the previous generation OSTRO VAM V1.
