  • 303 Firecrest Tubular Disc-brake
    Zipp’s 303 Firecrest Tubular offers game-changing innovations for performance-minded cyclists. This wheelset was developed to meet the needs of our sponsored professional racers – road and cyclocross – as well as any cyclist who prefer the time-proven ride qualities of riding tubulars.

    The 303 Firecrest Tubular Disc-brake features key technologies first developed for Zipp’s halo-level NSW wheelsets. Our ABLC Sawtooth dimple design that extends all the way to the edge of the rim. The rim features construction upgrades that deliver improved impact resistance. The Firecrest rim shape found 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 closer to the steering axis, giving the 45mm-deep 303 Firecrest rim the crosswind stability a box-section rim. And because the 303 Firecrest has been optimized for wider tires, ride quality and tire stability are better than ever. All of this provides excellence AeroBalance, which is how we define the optimization of aerodynamic efficiency and crosswind stability.

    When it’s 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.

    The cycle of innovation continues with the inclusion of the 77/177D hubset – proven durability and improved bearing protection with no pre-load adjustment needed.

    • Optimized flange geometry and spoke hole attachment pattern with Sapim CX Ray spokes to optimize torsional and lateral stiffness and robustness.
    • Includes quick-release skewers with a wider more ergonomic handle to provide more leverage for opening and closing. When closed, the lever contours neatly with the frame.
    • For those looking for a wider gear range, or tackling especially extreme terrain, an XDR 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 the wheel.
    • Included tool-free replaceable axle end caps for both QR and thru-axle configurations
    • 6-bolt rotor interface


    Technologies

    Firecrest - Not only is Firecrest more aerodynamic than any other rim design, it improves handling in crosswinds and overall ride quality.

    ABLC (Aerodynamic Boundary Layer Control) - Smooths airflow across the rim's surface and is tailored to every model from the 202 to the Super-9 Disc.

    VCLC (Visco-Elastic Constrained Layer Control) - Uses a vibration-absorbing material sandwiched between layers of rigid carbon laminate in the rim, 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. Reduces the vulnerability of the rim's tire bed, the area most susceptible to damage from impact.
