If perfection is the standard, then the 303 Firecrest wheelset delivers everything you could ask for, including a heritage forged – and still thriving – in the world’s toughest races. At the center of the 303 Firecrest Tubular is the 77/177 hubset, an innovation that results in improved stiffness, durability, simplicity and versatility.
Zipp’s original 303 made history by becoming the first carbon wheelset to win cycling’s two most famous Cobbled Classics, Paris-Roubaix and the Tour of Flanders. The 303’s wider rim provided extra durability, and improved aerodynamics. That wider rim also led to the development of our revolutionary Firecrest® platform platform that further reduces aerodynamic drag while increasing crosswind stability. The 303 Firecrest is a go-to wheelset for the pros of Boels-Dolmans, AG2R LA MONDIALE, Axeon Cycling and others.
Now the cycle of innovation continues with the inclusion of the 77/177 hubset – best-in-class durability and improved bearing protection with no pre-load adjustment needed.
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 45mm-deep rim the crosswind stability a box-section rim. And because the 303 Firecrest’s 26.45mm-wide brake track (at center) has been optimized for wider tires, the ride quality is better than ever.
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.
Available in two decal options, the stealthy Matte Black or the distinctive Matte White decals. Each 303 Firecrest Tubular wheel comes with Tangente Platinum Pro Evo brake pads, Zipp Integrated Valve Extender with valve-core wrench, 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.

New Zipp 303 "Classics" Road Wheelset May 2009
BIKERUMOR.com 2009 SEA OTTER CLASSIC COVERAGE: Zipp’s new 303 wheelset is “Ready for Anything” and was designed with the cobbles of classics like Paris-Roubaix in mind.
Despite being wider and taller, their weight is the same as the ‘08 303 wheelset, and Zipp claims they’re more aerodynamic! Built on their ultralight 88 and 188 front and rear hubs (named for their weights), the entire wheelset weighs in at a svelte 1182g (529g F / 653g R). The new hubs have 17mm axles with taller flanges, which improves the wheel’s stiffness.
TECH FEATURES: FIRST RIDE: 2010 SRAM FORCE AND ZIPP 303 WHEELS April 2009
Philip Booth of Road Bike Action gave the completely redesigned 303s a proper shakedown at SeaOtter.
Even though the Zipp 303s are designed for the cobbles of the Northern Classics, our first impression is that they should not be overlooked as all around aero wheels. The 303s would be ideally suited to a fast century or high mileage rider looking for an aero wheel that is easy to control and smoothes out the road.

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.
Carbon Bridge uses a Kevlar® thread in a co-axial helix stitch to bind sheets of carbon to each other in our tubular rims. Because Kevlar is 350% more impact resistant than carbon, it can disperse shock more evenly throughout the carbon laminate, making for a rim that is practically bulletproof. In particular, Carbon Bridge reduces the vulnerability of the rim's tire bed, the area most susceptible to damage from impact.
88/188 Hub Technology
Every aspect of our 88 and 188 hubs sets a new benchmark. The standard steel bearings are the roundest in the industry. The 17mm axle is the stiffest of any road hub we've tested. The wire EDM-cut hub internals are the most precise. When it comes to precision and performance, there's really no comparison.
