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.

  • 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.
