Enquire about this bike Start with a stock frameCan’t come to California?We can bring the build to you. Wherever you ride, we’ll work with you to create and finally crate up your new dream bike and deliver it to your door.
We do not often put a complete bike on the floor that is ready to ride, but this Ostro VAM was too good not to build exactly the way we wanted. After spending serious time on Ostro VAM ourselves, what we appreciate most is how naturally it handles everything asked of it, climbing with urgency, descending with confidence, and settling into long rides without drawing attention to itself. It is a production bike that rides with the coherence and intent we usually associate with custom builds.
This size 58cm build takes an already exceptional platform and pushes it further with thoughtful upgrades we value on the road. Titanium hardware trims weight and adds longevity, Hope brakes and rotors deliver consistent stopping power on fast descents, and CeramicSpeed OSPW RS Alpha Disc brings a tangible sense of drivetrain efficiency under load. Finished with Fizik Antares R7, this is a ready to ride Ostro VAM that reflects how we would build one for ourselves, for a rider who wants something special without waiting for a full custom project.

But today is the first day we get to show FACTOR’s new colors and share our first impressions of how it bui...

Factor Ostro VAM: A 1,000 Mile Review
After putting a thousand miles on a new Factor Ostro VAM, I have surprisingly few thoughts to share, and that is not a bad thing. Acquiring a stock or off-the-shelf bicycle takes fewer steps than getting a new custom-made bike: you choose a brand and model, and you're off. To do that, you can take friends' advice, buy the marketing spiel, read forums, and...

BOTW: A Factor OSTRO VAM TDF Edition
This customer came in a few weeks before our AC Invitational where we met to talk about a potential replacement for his road bike. After going over all of the options he settled on the new Factor OSTRO VAM in the limited TDF edition colorway. We took his existing fit, and put together a bike-cad to validate his position and so we could order the right siz...
