Thanks to Factor’s engineers’ expert carbon fibre lay-up techniques, commitment to premium materials, and the unique control their own factory offers, the new Ostro VAM performs in all areas – aerodynamics, lightness, responsiveness and comfort. This isn’t just innovation; it’s a reimagining of performance on two wheels, all designed to deliver an unmatched cycling experience.

 

The new OSTRO VAM is a sub-7kg aero weapon, so your crit bike is also your mountainous grand fondo bike and they’re both awesome. This lightness also means that the pros can use their most aero option more of the time (and for big mountain stages with summit finishes, there’s the feathery and fast O2 VAM). What’s more, the uprated stiffness level is mighty, unflinching in the face of even WorldTour watt bombs.

  • New Black Inc 48|58 Wheelset with Carbon Spokes and 48mm front and 58mm rear depth
  • Bike comes with innovative aero bottle cages which are location-specific and integrated into the frame’s aerodynamics
  • Super-thin aero seatpost – slender 15mm wide seatpost, capitalising on the latest UCI rules
  • Ultralight seatpost clamp
  • Black Inc Integrated Aero Barstem
  • CeramicSpeed T47a Bottom Bracked
