FACTOR O2 VAM

World's Fastest Climbing Bike

The new O2 VAM is an aero climbing bike – nothing else this light is as fast, nothing this fast is as light. It’s the ultimate choice for riders seeking performance on big days in the mountains, whether you’re riding the Étape du Tour or the Tour de France.

OVERVIEW

The new O2 VAM is for everyone looking for an enhanced, faster ride experience on mountainous and hilly terrain, with quicker climbing, more confident descending, higher speed on the flats and greater comfort.

It’s for gran fondo riders, racers, and those for whom a week in the mountains is the highlight of the year. If speed isn’t your priority, the increased efficiency will save you energy to ride further.

DESIGN

THE FASTEST LIGHT BIKE

The O2 VAM was born to climb, so it’s seriously light, from just 6.4kg out-of-the-box for a 54 with Shimano Dura-Ace Di2. Few disc brake bikes can compete and none of them are aero.

How aero is it? In the wind tunnel, at effective wind angles of 0-5 degrees (ie a calm day, or headwind to moderate crosswind) the new O2 VAM is only 5W behind the OSTRO VAM, which itself is the fastest aero bike on the market. Across a full sweep of angles, it slashes the gap by 50% versus the previous version. For such a light bike, that’s outrageous. On the road, it means that your climbing bike will be faster than many brands’ much heavier dedicated aero offerings.

The new O2 VAM is as stiff as the mighty OSTRO VAM and feels inspirational when you stamp on the pedals. You’ll be attacking just to feel it.

New Factor O2 VAM Design

DEVELOPED WITH THE PROS

The new O2 VAM is especially for the professionals to use on the toughest Grand Tour stages and Classics

The bike was developed, tested and validated with significant input from riders from the Factor-sponsored team, Israel Premier-Tech. Chris Froome helped give input into what the new bike should be and riders including Dylan Teuns test rode the new prototype at a high-altitude training camp in Andorra.

Black Inc 28/33

Built for the O2 VAM

The new 28//33 wheelset was designed to complement the new O2 VAM and represents an equally remarkable breakthrough in lightness and aerodynamics. The 28//33 weighs a feathery 1,146g as tubeless clinchers optimized for 28mm tires. They feature differentiated front and rear depths of 28 and 33mm, measure 23mm internally and 28mm externally, and use exceptionally light and strong carbon fiber spokes. As well as a substantial weight saving, they also reduce drag by 10g from the previous THIRTY wheelset and greatly boost stiffness, and therefore responsiveness and acceleration.

Key Features

To achieve ambitious goals for weight and stiffness, Factor invented a new manufacturing method, built an advanced new factory and use superior materials, including boron in the external seatpost to achieve an extreme strength-to-weight ratio.

The stack height of the new O2 VAM is 10mm higher. Factor studied the position data of thousands of our customers and athletes to find the dimensions that would enable the most riders to achieve their optimal fit.

The T47 standard for threaded bottom brackets ensures a secure fit, easy maintenance, and contributes to exceptional power transfer.

Generous tire clearance of 32mm allows you to choose the perfect tyre for the roads you’ll be riding.

The most visually apparent features of the O2 VAM relate to ride comfort as well as weight saving. The external seatpost, ultra-thin toptube and dropped seatstays all work together to promote controlled deflection at the saddle.

The sheer speed of the new O2 VAM is unprecedented for its category. It's made possible by Factor's engineers’ ground-breaking work to create all-new, aggressively truncated airfoil shapes for key frame sections.
