Ostro VAM v1

An all-round quiver killer. Searingly fast, incredibly light, supremely comfortable.

Refuse To Compromise

The OSTRO VAM is an ‘everything’ bike, a master of all trades. Searingly fast, incredibly light, and supremely comfortable, it’s ready to win sprints, mountain stages and cobbled Classics. It’s the ultimate all-rounder because it refuses to compromise. 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.

Lightweight And Aero

The OSTRO VAM is an aero disc-brake frame which weighs just 830g (painted, size 54, Chrome design). We have used the very best materials to reach such a low weight, laying up the ultimate carbon materials perfectly to ensure low weight, responsive ride, and durability. It can easily be built up to below the UCI 6.8kg weight limit, which is unique among aero frames. That means that the aero advantages come without the usual weight penalty. Few rides or race routes are exclusively mountainous or flat roads so, naturally, you want it all: speed and lightweight. The OSTRO is the everything bike, making you fast whatever the terrain.

Exceptional Comfort

As an aero racing bike that has proved itself on the cobbles of Paris-Roubaix, the OSTRO VAM will also be ideal for your roughest, longest roads. Its remarkably smooth ride is thanks to several factors. First the carbon fibre choice and layup combine to achieve a high level of frame compliance without sacrificing any of the power transfer efficiency. At the rear, the pencil thin seat stays are designed to absorb road noise and cushion bumps. And the ability to fit up to 32mm wide tires only enhances the OSTRO’s comfort-oriented design features.

Geometry And Fit

You can make a bike as light and aero as you like, but if you get the fit wrong, you’re not going to be enjoying your rides. To feel comfortable and have confidence in your handling, it’s essential to match your style to the right geometry. The OSTRO VAM is a pure racing bike intended to get the rider into an aggressive stance, and consequently they all share very similar geometries throughout the sizes. Geometry standardization makes it easier for our pros to switch between bikes during races, and it will help you stick to your comfort zone for your most important events.

Engineered For Speed

The goal was to create the lightest aero-oriented bike in the pro peloton. The OSTRO VAM is a bike that can be competitive on any terrain. It is ready to win sprints, conquer cobbled classics, and summit the climbs with the best.

Get Your SLT Bearings

Working closely with CeramicSpeed when developing products allows Factor to help find the best technical solutions for the ultimate racing bikes. Early in the concept design phase, our R&D team was testing CeramicSpeed’s SLT (Solid Lubrication Technology) Bearings for headsets, giving our feedback in the development of the indestructible headset bearings that we have been using with our road bikes since March 2021. The SLT bearings have proved they are guaranteed to last. Requiring no maintenance, they are particularly useful when combined with an integrated cockpit. The SLT bearings solve the problem of headset maintenance for integrated cockpits by removing the need!

Detailed Aerodynamics

Though aerodynamics and lightweight frequently are playing tug-of-war, the OSTRO VAM design makes sure these two essential considerations are both pulling in the same direction. In designing the OSTRO, Factor considered every aspect of the frame and applied the optimum aero profile, with particular regard to the transitions between frame sections and to performance across a full range of effective wind angles. The tube profiles are derived from NACA (National Advisory Committee on Aeronautics) shapes, oriented along the waterline (horizontal) in line with airflow and optimised for ride quality and aero-to-weight balance by truncating the aero section aggressively.

Full Integration

The one-piece, aerodynamic Black Inc Barstem reduces drag by meeting clean incoming airflow with a clean shape. Fully internal cabling brings further gains and Factor has achieved this while maintaining a 1⅛” top headset bearing for optimised frontal area, whereas many other brands increase the head tube size to accommodate internal cabling, cancelling out the benefits. And the introduction of CeramicSpeed SLT Bearings removes any worry of headset maintenance.

In line with customer demand and facilitating a reduction in aero drag and weight, the OSTRO VAM is built exclusively for electronic shifting groupsets.

Basing our fork offset on the size of the frame ensures optimum handling characteristics across all frame sizes so that every customer has the best ride experience.

The T47 standard for threaded bottom brackets ensures a secure fit and easy maintenance. It allows for the use of a wide range of crank spindle diameters and helps keep the bottom bracket shell robust for exceptional power transfer.

Enhancing comfort and making the most of the aerodynamic benefits offered by Black Inc’s wide rims, the OSTRO VAM can accommodate up to 32mm tires.
