The OSTRO is an ‘everything’ bike, a master of all trades. Fast, incredibly light and comfortable, it is ready to win sprints, mountain stages and cobbled Classics. If you’re the sort of rider who races with ‘the knife between your teeth’ no matter the parcours, this is the bike you’ve been waiting for. When we say you can have it all, we mean it.
The OSTRO is an aero race bike that’s ready for Paris-Roubaix. It’s a ground-breaker on the cobbles, whereas usually it’s the cobbles that break riders.
The OSTRO achieves its remarkably smooth ride in three key ways: tyre clearance, ultra-thin seat stays, and carbon fibre layup.
780g for a painted frame in size 54 Flicker design, achieved through Factor’s industry-leading carbon fibre expertise and mass-optimised aero profiles.
Optimises aerodynamics by widening the gap between the fork legs and the spokes, reducing the turbulence caused by the forward rotating spokes meeting incoming airflow, and gives clearance for a 32mm tire
Identical geometry to the O2 and O2 VAM. Consistent geometry makes it easy for our pro riders to switch bikes and for our customers to choose based on their riding.
Drawing on technology from the new O2 VAM, the OSTRO routes all of its cables 100% internally.
The OSTRO achieves exceptionally high frame stiffness for the category by using truncated airfoil profiles, resulting in stiffness levels at or above that of the O2.
Used for the first time in a Factor, the T47 standard ensures a secure fit and easy maintenance.
Mid-depth profile seatpost balances weight and aero, available in 0 and 25mm offset options.
