Ostro Gravel
The Factor Ostro Gravel is an aero-focused gravel race bike derived from the Ostro VAM road platform, with a claimed 900g frame (56cm) and clearance for 45mm tyres. Reviewers praise its stiffness, aerodynamics and fast handling, though its aggressive, road-derived geometry and firm ride limit comfort on rough terrain. It is built around a T47 threaded bottom bracket and electronic shifting only.
