he ZIPP 303 Firecrest Carbon Clincher disc-brake wheelset is now able to be Tubeless. At the center of the wheelset is Zipp's 77/177D hubset, an innovation that results in improved stiffness, durability, simplicity and usability.
When it is time to scrub off speed or stop, you won't have to tense up and 'grab a handful'. You have the consistency and power of disc brakes - precision modulation and stopping power is at your fingertips. You also get the unmatched stability and aerodynamic efficiency of the pro-proven 45mm deep 303 Firecrest rim and the added convenience of clincher wheels.
The 303 Firecrest Disc-brake wheel set combines that innovative disc-brake-compatible technology with the credibility and heritage of one of Zipp's most acclaimed wheels, the 303.

Firecrest Technology
In developing the original 303 wheels, Zipp discovered that a wider rim increases lateral stiffness for sprinting and cornering while also providing greater vertical compliance for greater control, comfort and durability. That wider rim profile led ZIPP to develop our Firecrest technology, which revolutionized aerodynamic efficiency and stability for carbon wheels. The proprietary Firecrest rim shape optimizes the aerodynamic profile of the front half and - here's the revolutionary part - the back half of the wheel. Firecrest moves the wheel's center of pressure to be more in line with the steering axis for stability in even the stiffest crosswinds. All of that innovation along with the precision control of disc braking gives you a wheel that's as smooth as it is tough.

ABLC and VCLC
You'll also see the rim skin is embossed with lot's of dimples of different diameters in a pattern which forces the airflow to form thinner, turbulent boundary layers. This significantly reduces the interference drag. The turbulent layer also adheres to the wheel skin throughout an increased airflow angle of attack, resulting in significantly lower drag in cross-wind situations, which means you have even more control with the ABLC (Aerodynamic Boundary Layer Control) rim. ABLC increases handling performance by minimizing the low-pressure wake left behind the wheel, allowing for greater tire choice with fewer aerodynamic side effects than seen with other designs. Zipp's exclusive VCLC (Visco-Elastic Constrained Layer Control) technology dramatically reduces rider fatigue, particularly in the hands, arms, neck, and posterior - while greater control of the tire contact patch simultaneously improves cornering grip and minimizes rolling resistance.

About the 77/177D hubset

bearing preload precision set - that means no pre-load adjustment is needed
improved bearing protection and sealant
includes newly designed quick-release skewers with a wider more ergonomic handle to provide more leverage for opening and closing
Thru-axle compatible - comes with FW: 12x100mm, 15x100mm / RW: 12x142mm (X-12), 12x135mm thru-axle end caps that can be swapped by hand
proprietary flange geometry and spoke hole attachment pattern with Sapim® CX-Ray® spokes to optimize torsional and lateral stiffness without sacrificing weight or robustness
17mm internal axle


The ZIPP 303 firecrest disc clincher rear wheel features an 11-speed freehub for SRAM/Shimano.
Optionally for those looking for a wider gear range, or tackling especially extreme terrain, a SRAM XD 11-speed driver body for 177D can be easily installed to allow for more cassette options.
