As an integral design feature of the Factor ONE, the ONE Seatpost maintains a steeper seat tube angle that brings the rider’s saddle mounting point forward. The ONE has an extremely progressive fitting geometry, reflecting the increasing trend of riders looking for more forward positions and less setback relative to the bottom bracket.

The ONE offers two seatposts, providing the equivalent of zero and 30 mm setbacks with a seat tube angle range of 73.5° or 76°. The positions of the two seat posts were chosen not only to accommodate all riders on our professional teams, but to enable riders to achieve the UCI minimum setback of 0 mm from the nose of the saddle to the centerline of the bottom bracket, while keeping the saddle rails properly supported.

Though designed specifically with aerodynamics and an aggressive position in mind, the Factor ONE Seatpost also uses intelligent features to improve the overall usability of the product. For instance, it employs the same OSTRO VAM-style two bolt seat clamp for ease of adjustment and a secure hold.
