Factor OSTRO VAM Ultegra Road Bike

Built to dominate every ride, the OSTRO VAM Ultegra Road Bike was designed with one clear mission: to be the lightest aero-oriented bike in the professional peloton. From powering over cobbles, cresting Belgian bergs, to beating local KOMs, the Ostrom VAM delivers a responsive ride to get you ahead of the chasing pack. And with Shimano's Ultegra Di2 in charge of shifting and braking, this is a bike you'll love to ride fast. 

Engineered for Speed and Versatility

Whether you’re sprinting for the line, tackling cobbled classics, or climbing alpine passes, the OSTRO VAM adapts seamlessly to every challenge. It’s not just competitive—it’s commanding. Each ride becomes a statement of speed, precision, and control, setting a new benchmark for all-around race performance.

Unrivalled Performance Backed by the Numbers

The OSTRO VAM is 250 grams lighter and 7 watts faster than its predecessor, making it a force in both aerodynamics and responsiveness. Factor’s engineers utilised advanced computer modelling to sculpt every millimetre of the frame for optimal airflow. After 40km, the OSTRO VAM leaves its predecessor and competitors far behind. The refined head tube and airfoil frame profile ensure exceptional aerodynamic gains verified through extensive wind tunnel testing. Simply put, no other bike in its class cuts through the air like the OSTRO VAM.

Revolutionary Black Inc 48|58 Wheels

Complementing the frame is the new Black Inc 48|58 wheelset, purpose-built to enhance stability and aerodynamic efficiency. With differentiated rim depths, 48mm at the front and 58mm at the rear, these wheels deliver precise handling in crosswinds while maintaining blistering straight-line speed. The 23mm internal rim width, optimised for 28mm tyres, ensures a smooth and predictable ride, while carbon fibre spokes and high-flange hubs keep weight to an astonishing 1,250g. Every component contributes to faster acceleration, superior control, and effortless climbing.
