Zipp 303 Firecrest Tubeless Disc CL 700x 12x142mm Rear Wheel

Zipp 303 Firecrest Tubeless Disc CL 700x 12x142mm Rear Wheel

The Zipp 303 Firecrest® Tubeless Disc Brake Wheelset is designed for the real world... a world of imperfect conditions, road surfaces and elements where the end result is simple. Efficiency = speed. It's faster, lighter and more capable on varied terrain, whether the surface is full pavement or no pavement. Deeply rooted in Zipp's drive to conquer the Spring Classics, the new 303 Firecrest is remade with a specific approach to the demands of modern road bikes. When it comes to going fast on a bike, efficiency means reducing: wind resistance, rolling resistance, rider fatigue, weight. The 303 Firecrest tubeless disc brake was designed using direct real-world measurements (vs. primarily wind tunnel or computer simulation). The results were enormous. Its rim has a slightly more bulbous design than its predecessor, with an external width of 30 mm, an internal width of 25 mm and a rim depth of 40 mm. The profile provides low drag and an improved transition between rim and tire, increasing aerodynamic efficiency on the road. The wide rim stance also features less tire deflection to reduce rolling resistance. The combination of the wider tire, increased tire volume, and lower tire pressure helps reduce rider fatigue by smoothing the ride over imperfect pavement and road conditions - the tire and wheel system absorbs shocks , not the cyclist. At the heart of the 303 Firecrest Tubeless Disc Brake is a versatile and durable new hub set, the German-engineered ZR1 DB. This hubset features 66 engagement points for faster response. The 303 Firecrest Tubeless Disc-brake wheelset is for dedicated riders who aim for the latest in technology. Your competitors in races, against peers, or simply conquering personal limits. It's about getting faster and matching your motivation with the latest technology.
