Factor Bikes has been pushing the limits of performance for years. With their own factory in Taiwan and a lofty engineering team that gets direction from none other than the legend, Chris Froome, their racy Ostro VAM is getting a full makeover for 2024. With wins already this season on the new bike, team Israel — Premier Tech aims to use the Ostro VAM as their primary bike for just about every race on the calendar.
From 2017 to 2020, I rode and loved the lightweight Factor O2 Disc. Now, four years later, the Ostro VAM has dropped more weight (almost rivaling the O2’s weight), added more aerodynamics and applied lessons learned throughout the years to deliver more comfort and control. The shapes look similar, but every tube shape has changed on the new Ostro VAM. And, every key metric has also been improved over the V1 model.
With all these new tube shapes, the purpose of the Ostro VAM remains the same — crush the competition. The geometry remains aggressive and full integration is on display, but it’s hard to ignore the beauty of the Ostro VAM’s sleek lines. It’s a beauty and represents the brands desire to find that optimal balance between weight, stiffness and aerodynamics. That winning formula is one that the Pinarello Dogma has enjoyed for years as the winningest do-it-all bike on the World Tour and one that Factor certainly has its sights set on.
“With the launch of the new OSTRO VAM, we are pushing the boundaries of carbon bicycle design and production to improve on what was already a proven winner. Overall victory in the 2024 Santos Tour Down Under was a dream debut for the OSTRO VAM, and we look forward to seeing pro riders and consumers alike reach new heights with this bike.” – Rob Gitelis, founder of Factor Bikes

Looks like an aero beast! I love all the configuration options at FACTOR. Stongly considering them for my next steed.
Such a beautiful bike, right? I would gladly ride this over the bikes from the usual suspects.
