If perfection is the standard, then the 303 Firecrest wheelset delivers everything you could ask for, including a heritage forged in the Spring Classics. At the center of the 303 Firecrest Carbon Clincher is the 77/177 hubset, an innovation that results in improved stiffness, durability, simplicity and versatility.
Zipp’s original 303 Tubular made history by becoming the first carbon wheelset to win cycling’s two most famous Cobbled Classics, Paris-Roubaix and the Tour of Flanders. Its wider rim provided extra durability, and improved aerodynamics. That wider rim also led to the development of our revolutionary Firecrest® platform, and now the revolution continues with the inclusion of the 77/177 hubset – best-in-class durability and improved bearing protection with no pre-load adjustment needed.
- Optimized flange geometry and spoke hole attachment pattern with Sapim® CX Sprint spokes to optimize torsional and lateral stiffness and robustness.
- Includes newly designed quick-release skewers with a wider more ergonomic handle to provide more leverage for opening and closing. When closed, lever contours neatly with the frame.
- New robust hub platform with distinctive graphics.
- For those looking for a wider gear range, or tackling especially extreme terrain, a XD driver body for 177 is sold separately and easily installed to allow for more cassette options including a 10-42. The hubset is designed to swap driver bodies without re-dishing wheel.
Zipp’s Carbon Clincher technology preserves the aerodynamic advantages of the 303 Firecrest’s tubular brother, while adding the convenience of a clincher tire. And at just 1,645g, it’s light enough to climb up the steepest gradients with ease as a go-to all-around wheelset.
The Firecrest shaping optimizes the aerodynamic profile of both the front half and the back half of the wheel. In addition, Firecrest moves the center of pressure of the wheel backwards, giving the 45 mm-deep rim the crosswind stability a box-section rim. At the same time, the 26.4 mm-wide brake track (at center) allows the clincher tire to take on a wider, more stable shape without compromising rolling resistance. It’s faster, simpler, and more stable.
The new wheels retain all the small details that make Zipp wheels what they are. Exposed spoke nipples sit in the aerodynamic shadow of the rims, keeping serviceability simple without compromising speed. And our signature ABLC™ rim dimples squeeze every last second of performance possible.
Available in two decal options, the stealthy Matte Black or the distinctive Matte White decals. Each 303 Firecrest Carbon Clincher wheel comes with Tangente Platinum Pro Evo brake pads, Zipp Integrated Valve Extender with valve-core wrench, rim tape and quick release.

The wide profile of the 303 Firecrest is crucial to Zipp’s revolutionary Firecrest technology used to create wheels with superior aerodynamics as well as improved stability and handling.
The rear 303 Firecrest, however, may present some fitment issues for a small number of road and triathlon frames. The clearance between the chainstay and the rim may not be adequate to avoid contact between each other when ridden under load.
We urge customers who plan on riding the 303 Firecrest to test the wheel within the frame in which they intend to ride, under normal riding and road conditions, before purchasing. Clearance within individual frames of the same size, from the same manufacturer, may vary. That is why it is imperative that you test the wheel in your frame, or in the frame that you are considering purchasing.

When you open the box and take the wheels in your hands you know something is special with them. The built quality is second to none and the look is classy. The ride: I own a S-WORKS Roubaix SL4 WITH A Sram Red groupset. I mount Vittoria Open Corsa SL 700x24 with latex tube on them from April to September and Open Pave 700x25 from October to February . On good asphalt, it seems that you are floating upon the road. The wheels are stiff and comfortable at the same time. They encourage you to push on the pedals and once you reach a good pace you just have to keep it going. Sometime, you go back home and feel like you could have gone for a few more kilometers. As they are not the lightest, when the grades elevate you feel like you are slow. But if you analyse your climbing segments you will notice they are equal or even better than so called climbing wheels... The only downside is Braking in the wet. You need to pulse your break before getting some biting. Once you know it, it's okay. In the dry, the braking is amazing. Since i ride them, i've never spent so much time hands down in the bar to optimize aerodynamics. The bearings are smooth and if you take the front wheel in hands and make it turn you realize their quality. In strong negative wind (worst yaw angle) the wheels gently absorb gusts and maintaining your bar is easy. As soon as the wind comes from the back and the back sides you benefit of a zero drag seems like you have a motor pushing you forward !!!
