Summary
The Factor Ostro is an aero-focused gravel race bike designed for speed and performance on smooth terrain. It excels in stiffness, aerodynamics, and handling, making it a top choice for racing and fast rides. However, it sacrifices comfort and versatility, with a firm ride that can be harsh on rough surfaces and limited utility for diverse conditions.
Incredible aerodynamics
High stiffness for efficient power transfer
Superior handling on smooth terrain
Lightweight construction
Premium componentry and build quality
Firm and uncomfortable ride, especially on rough terrain

Quick steering can be unstable on technical descents
High price point for a specialized machine
Limited utility features like mudguard mounts
developed to dominate its category with incredible aero, superior handling, high stiffness and low weight
On smooth, well-graded gravel it is like being shot out of a cannon.
It’s a gravel bike for race day, designed with winning in mind through and through.

The collab tells the story of how cycling saved the career of pro skateboarder Chico Brenes – but what has that to do with the turquoise-browed motmot, the national bird of Nicaragua? All will be revealed…

The bike that encompasses Factor and its presence worldwide is the OSTRO. It's the most recognizable of its offerings and just got an update.
