FAQ

What kind of rider is the Ostro VAM built for?

The Ostro VAM is Factor's aero road race platform, designed for riders who want one high-performance bike that can sprint, climb, and hold speed on the flats. It is the bike Israel Premier Tech races at WorldTour level, and the sub-7kg complete weight means it punches above its weight in the mountains while still cutting through wind like a dedicated aero bike.

Is this bike compatible with mechanical drivetrains?

No. The Ostro VAM is designed exclusively for electronic groupsets. Fully internal cable routing and integrated cockpit design do not accommodate mechanical shift cables. This build uses SRAM Force AXS E1 wireless electronic shifting.

What is the maximum tire clearance?

Factor rates the frame for up to 32mm tires.

What makes the Watercolour finish special?

The Watercolour is one of Factor's signature paint schemes, a hand-blended pastel gradient that flows across the frame in a way no two bikes look identical. It is one of the most visually distinctive finishes in road cycling and a common reason riders choose Factor over competitors with more conservative paint programs.

Can I customize this build?

Yes. This bike is in stock as built, and the whole build is fully customizable. Stem length, bar width, crank length, cassette ratios, saddle, and wheel choice can all be swapped to dial in your fit and preferences. Reach out to the shop to discuss options.
