Factor Ostro

The Ostro is built with a race-focused geometry, meaning it prioritizes speed, stiffness, and aggressive handling. While it is certainly capable of casual rides, it excels in competitive gravel events where efficiency and aerodynamics are critical.

Yes, the frame is compatible with both 700c and 650b wheelsets. This flexibility allows you to tailor your setup based on the terrain, whether you prefer the rollover efficiency of 700c or the added agility and volume of 650b.

The frame offers generous clearance for tires up to 45mm wide. This provides enough volume to handle rougher, technical surfaces comfortably without sacrificing the bike's aerodynamic performance.

The Ostro utilizes the Universal Derailleur Hanger (UDH) standard. This is a significant advantage for long-term maintenance, as it makes finding replacement parts much easier compared to proprietary hanger systems.

The frame uses a zoned strategy that optimizes the front end for clean airflow while focusing on weight reduction in the rear. This creates a bike that cuts through the wind efficiently while remaining light enough to handle steep climbs and technical accelerations.

CeramicSpeed bearings are known for their high efficiency and durability, but they do require periodic cleaning and re-greasing to maintain their performance. They are a premium component choice that rewards regular, proper upkeep with exceptionally smooth operation.
