Brand new uncut Oval Concepts A900 aero full carbon fork. 650c(700c available as well) New and uncut with special aluminum top cap insert. This is the deep aero fork with the channel on each of the fork blades. Full carbon and i think it’s meant for an integrated headset, sure looks like it from the crown. Never mounted. Carbon steerer, crown, and blades, aluminum dropouts.

from the Oval site:
When it comes to equipment, the wheels generate the most aerodynamic drag, and the front wheel is the worst offender.
The drag is greatest at the top of the wheel, where the wheel’s forward motion means it rips through the air at twice the bike’s speed in still air. This creates a tremendous amount of turbulence, which any first-year aerodynamics student will tell you equals increased drag. The A900 helps manage airflow in this critical area by directing this turbulent airflow through its slotted venturis, compressing this turbulent flow back into a smooth, laminar stream. What’s more, the airstream exits the fork in an outward direction, which helps strip the turbulent, drag-producing layer of air away from the spokes as they approach the fork blade and provide a further drag reduction.
Our Jet Stream carbon aero fork was inspired by nearly 20 years of experience gleaned from experimental wind tunnel testing, by one of cycling’s most influential aerodynamic gurus. Its unique design channels airflow through its slotted blades to strip the turbulent, drag-producing layer of air from the front wheel, helping to preserve smooth, laminar flow around the wheel. Translated into terms every racer can understand, this means a 55-second time savings over a 1-hour time trial at 50 km/h. That’s more than a winning margin. That’s a crushing victory.
