Versatile Endurance Wheelset for the Modern Road Cyclist — 303 Firecrest

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.

Built With Purpose.

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 30mm outside width, a 25mm internal width, and a 40mm rim depth.

Aero Efficiency & Reduced Rider Fatigue.

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.

    Slightly less QC during pandemic

    I had my eye on these wheels since they came out.

    My order - BTD had a "20% off entire cart day" AND these were actually just backordered, so I took the plunge. The backorder took less time than estimated, so that was a nice surprise.

    The product -

    There seems to a slight quality control issue with some extra material (bonding plastics or machining flash or even masking material) remaining around each of the spoke holes. I spent an evening carefully plucking the extra material from the spoke holes with tiny needle nose pliers. My guess is that our pandemic has the manufacturer scrambling to operate with the highest quality control possible. Not such a big deal to me.

    Other than that:

    The wheels are great to ride on, on mixed surfaces.

    The branding stickers are not durable at all. I have already got a nice scratch through one of them from lite contact with a plastic tire level. At first, I really wanted to remove the stickers, but I read that that would void the warranty...

    Overall, I'm very happy with these and will treat them as bombproof on and off road.

    Wider and lighter

    Bought this to replace Roval CL 50 wheelset on my BMC Roadmachine. The Firecrests are lighter, have a hub that engages faster, are less buffeted in the wind and the wider width allows me to run lower tire pressures. I like a stealth look so I peeled off the decals. I set them up with Schwalbe Pro One TLE 2020 tires and Orange sealant. Tires were easy to mount, air up and sealed with no issues. Great wheelset.

    Everything I hoped for

    Pick a superlative and it applies to this wheelset. Fast. Light. Amazing price. Easy set-up. Great warranty. Good looking. What else do you need?
