Zipp 303 Firecrest Tubeless wheelset: all-terrain for the new era of road cyclingZipp 303 wheelset has a great tradition, but it is full of new features. This wheelset has an internal width of 19mm and is tubeless ready. That means you can ride at lower pressure, for more cornering grip and responsiveness, and less rolling resistance, without the risk of punctures.

It's lightweight, and features ABLC™ Sawtooth™ technology, a complex dimple pattern that was first developed for our top-of-the-line NSW line of wheels. This technology allows us to achieve aerodynamic optimization and stability against side winds, which we call AeroBalance™. Zipp's ShowStopper™ textured braking surface delivers unrivaled braking performance in wet or dry conditions. At the heart of the 303 Firecrest Tubeless Rim Brake is a versatile and durable hub, the ZR1 DB, designed in Germany. Characteristics:

• The new ZR1 hub has been designed in Germany and offers a better seal, so it lasts longer and has a faster response, thanks to its 66 anchor points.
• J-spoke Sapim CX Sprint
• Tubeless, which ensures performance even at lower pressures.
• Versatile 45mm profile that's also fast and stable
• ABLC Sawtooth™ dimple design improves airflow management around the rim and helps create a faster, more stable wheel.
• Showstopper™ textured braking pad that offers greater modulation and stopping in less distance, in dry and wet conditions.
