Zipp’s 303 Firecrest® Tubeless Disc-brake wheelset is designed for the real world… a world of imperfect conditions, road surfaces, and elements where the bottom line is simple. Efficiency = speed. It’s faster, lighter, and more capable over varied terrain—whether the surface is pavement in all its conditions or no pavement at all. Deeply rooted in Zipp’s drive to conquer the Spring Classics, the new 303 Firecrest is remade with a purpose-made approach for the demands of modern road bikes. When it comes to going fast on a bicycle, efficiency means reduced: Wind resistance, rolling resistance, rider fatigue, weight. The 303 Firecrest Tubeless Disc-brake was designed using real-world direct measurements (vs. primarily wind tunnel or computer simulation). The results were huge.
Its rim is slightly more bulbous in design than its predecessor, with a 32mm outside width, a 25mm internal width, and a 40mm rim depth. The profile provides low drag and an improved transition between rim and tire, boosting aero efficiency on the road. The wide rim stance also features less tire deflection for reduced rolling resistance. The combination of the wider tire, increased tire volume, and lower tire pressure helps to reduce rider fatigue by smoothing out the ride over imperfect pavement and road conditions—the tire and wheel system absorbs the shaking, not the rider. At the center of the 303 Firecrest Tubeless Disc brake is a versatile and durable new hubset, the German-engineered ZR1 DB. This hubset features 66 points of engagement for quicker response.
The 303 Firecrest Tubeless Disc-brake wheelset is for dedicated cyclists who aspire to the latest in technology. Its competitors… in races, against peers, or simply conquering personal limits. This is about becoming faster and matching your motivation to the most advanced technology.

Zipp 303 Firecrest wheelset
Bought these Zipps to replace my Hunt 35 Aero disc wheels on my gravel bike as at 83 kg they they didn't feel stiff enough. Fitted black 28mm Veloflex EVO TLR tubeless tyres that did require tyre levers to coax them on. Once inflated, very little sealant came through as they sealed. Tyre width came up as 29.8mm. Wheels fitted, they look classy and very understated. First ride impressions - beautifully responsive and hold speed very well for a 40mm deep wheel. Ride comfort with tubeless set up was also excellent. These wheels have turned my gravel ride into a fast road bike.
Zipp 303 Firecrest Carbon Clincher Disc Break
Purchased both front and back from ProBikeKit and was excited to try a tubeless set up. The Wheels showed up quickly and undamaged as they were packed very securely. I couldn't get the tires on the rims and had to get them professionally mounted, and it was a bit tricky to get them properly seated, and sealant added... Now they are set and holding air. These wheels are the biggest update I have done and they were well worth the $$. They are super light and responsive and a lot faster... Sill getting used to running at 55 psi. I would highly recommend these wheels.
