Improving one of the most proven wheels on the market is no small task, but with the new 303 Firecrest Tubeless Disc wheel, Zipp did just that. And then some. Each details has has been reworked to create a wheelset that is faster and better performing in every way.

For one, they're lighter. A lot lighter. 300g lighter. At 1,355g, they're one of the lightest aero, disc brake wheels out there. They're also smoother. Purposefully engineered for maximum vibration damping and compliance, resulting in reduced energy loss, and less fatigue when the terrain gets rough. Smooth is speed. All the way down to the center, the new 303 is outfitted with a newly redesigned hub, featuring an improved 66 points of engagement, and better seals so you can journey further into the unknown.
