A COOL THING ABOUT CYCLING is that you can buy speed. Get a lighter frame, a lighter wheelset, lighter tires... You will be faster. If you're reading about this wheel you probably already know that your wheels are the best place to add speed, and on a time trial bike you've got to have an aero wheelset.

The Zipp Sub-9 Tubular Disc Wheel is known for it's positive drag wind tunnel tests, which basically means this wheel turns itself! Many Zipp innovations are at work in this wheel, such as Aerodynamic Boundary Layer Control bulged rims to maximize aerodynamics by keeping airflow on the disc surface; Visco-Elastic Constrained Layer Control technology, which delivers a 10% reduction in vibration and muscular road fatigue no matter how fast or how long you're riding; Inversion Composite Technology, which results in a lighter, stronger, stiffer, and faster wheel. If you are serious about improving your time trials or bike splits, aerodynamic wheels are a must, and the Zipp Sub-9 carbon disc sets the standard.
