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.
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.
Customers who run into this fitment issue may select any other spoked wheel within the Zipp lineup as an alternative, including the 404 Firecrest with its narrower aero-width profile.
Below is a list of known frames that may present this issue. This list will be updated if this fitment issue is discovered elsewhere.

Quote from Velo — September 2014 Issue
Remarkable Speed Feelings February 2014
Ciclismo a Fundo (Portugal) tested the Zipp 303 Firecrest Carbon Clincher in its February 2014 issue.
In Portugal, the total amount for a set of Zipp 303 Firecrest Carbon Clincher is 2,525 euros, 1,138 euros for the front and 1,387 euros for the rear wheel. In addition to the brake pads, the Zipp 303 are sold with valves extenders and tools, rim tapes and quick releases. But for that price, the brand doesn't offer carry bags.

Ciclismo a Fondo – Sergio Palomar (Jan 2012)
With the new proprietary Firecrest rim shape in our 202, 303, 404 and 808 Firecrest wheels, Zipp wheels make a bigger difference in more ways than ever. Not only is Firecrest more aerodynamic than any other rim design, it improves handling in crosswinds and overall ride quality.
Our superior Carbon Clincher technology is the culmination of two years of intensive prototyping and testing. We worked with our composites supplier to develop an exclusive heat-resistant resin based on the materials used in motorsports brake systems. This proprietary technology improves heat management so substantially that all Zipp Carbon Clinchers pass stringent CEN safety standards.
ABLC™ (Aerodynamic Boundary Layer Control)
Advanced Boundary Layer Control (ABLC) refers to the patented and instantly recognizable dimpled pattern found on all of our carbon rims. ABLC smoothes airflow across the rim's surface and is tailored to every model from the 202 to the Super-9 Disc. The third-generation of ABLC has up to four times more dimples than before.
VCLC™ (Visco-Elastic Constrained Layer Control)
Visco-Elastic Constrained Layer Control (VCLC) uses a vibration-absorbing material sandwiched between layers of rigid carbon laminate in the rim. When the wheel receives an impact from the road, much of the shock is absorbed by the VCLC system, delivering a 10% reduction in vibration.
Electron Discharge Machining allows us to cut the materials for our rear hub drive internals after they’ve been hardened through heat treating, negating the warping and imprecision caused by the heat-treating process.
Zipp is the only company specifying Swiss made highly specialized ball bearing cartridges. Working with a family owned Swiss bearing manufacturer, Zipp is able to attain a superior level of bearing smoothness and long life. Zipp ball bearings are specified to 10 millionths of an inch tolerance, guaranteeing that they are at least 2.5 times rounder and better matched than most company’s “high precision” balls, and more than five times tighter than most “precision” balls.
