It's the result of Zipp's quest to dominate the springtime classics. That's why the new Zipp 303 Firecrest Carbon Disc has been redesigned using a concept specifically tailored to the needs of modern bikes. When it comes to riding a bike quickly or To drive even faster, the following parameters must be reduced: wind resistance, rolling resistance, driver fatigue and weight. 

Zipp 303 Firecrest Carbon Disc wheels are tested in real world conditions (as opposed to wind tunnel or computer simulations) using direct measurements. The results were overwhelming. With an outer width of 30 mm and an inner width of 25 mm, the rim is also well equipped for the roughest terrain. The profile provides low drag and an improved transition between rim and tire, increasing aerodynamic efficiency on the road. The wider rim design also features less tire deflection for lower rolling resistance.

The combination of wider tyres, increased tire volume and lower tire pressures help reduce driver fatigue by smoothing the ride over imperfect road and surface conditions to a certain extent: tires and wheels absorb the shock, not the driver. At the heart of the Zipp 303 Firecrest Tubeless Disc Brake wheelset is a versatile and durable new hubset, the Zipp 77 and Zipp 177. 

Conclusion: The Zipp 303 Firecrest Tubeless Disc-Brake wheelset is for dedicated cyclists who demand state-of-the-art technology. With what goals in mind? Win races against competitors, push your limits and set personal records. So this wheelset is all about going faster and balancing your ambitions with the most advanced technology.
