Factor Bikes OSTRO VAM


The OSTRO VAM is a versatile aero road bike that combines aerodynamics, low weight, and comfort. It's engineered to excel in varied conditions, from sprints to mountain stages, making it a favorite among professional riders who need a bike that can perform well in any situation. The OSTRO is Factor's fastest road bike to date, designed to beat the fastest bikes out there. 

According to Factor, this new iteration of the OSTRO VAM is lighter, faster, and unbeatable (that last part might be down to you). The updated OSTRO enters the race 250 grams lighter than its already ludicrously light predecessor.

Factor’s goal when making the OSTRO VAM  was to create the lightest aero-oriented bike in the pro peloton. But it’s no one-trick speed pony. The OSTRO VAM is a bike that can be competitive on any terrain, ready to win sprints, conquer cobbled classics, and summit the climbs with the best.
