	OVAL Concepts Jet Stream Aero Fork A900 700C Carbon 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. 495g		Price:	QTY:

	OVAL Concepts Jet Stream Road Fork R900 700C 1-1/8 Carbon Our revolutionary A900 time trial fork created a splash in the triathlon world when it debuted last year, and this year we’re taking that technology on the road with the R900 road fork. It’s a fact—your bike’s wheels generate more aerodynamic drag than any other piece of equipment. And aerodynamically speaking, a road racing wheel is a mess. The exposed spokes and low-profile rims are terrible enough by themselves, but when you set the whole works in motion it becomes a giant turbulence generator. And turbulence, as any aerodynamics student will tell you, equals drag.445g The drag is greatest at the top of the wheel, where the spokes’ forward motion means they rip through the air at twice the bike’s speed in still air. The R900 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. Because road racing wheels aren’t as aerodynamically optimized as time trial wheels, the R900 can have an even greater drag-reducing effect than the A900, which is good for a 55-second advantage in a one-hour time trial at 50 km/h (31 mph). That’s just too much of an advantage to ignore.		Price:	QTY:
