45mm Deep
The 45mm deep 303 Firecrest delivers unmatched aero performance when used with the wide tires that today’s riding demands. Zipp has achieved this with a wide disc-specific rim design featuring ABLC dimples extending all the way to the outer edge of the rim. In addition to achieving AeroBalance™, the industry-leading crosswind stability and low aerodynamic drag that defines all Firecrest wheels, the new 303 Firecrest delivers lower drag than the outgoing version when used with 25c or wider tyres. The aerodynamic performance gap between a narrower rim and the new 303 grows even larger with 28c and wider tyres thanks to a smoother transition between the tyre’s profile and Zipp's new rim shape.
Tubeless Rim
Designed from the start as a tubeless rim, the 303 Firecrest features a rim bed made with internal ridges to lock the tyre’s bead in place, ensuring secure performance, even when ridden at lower tyre pressures. Setup tubeless and emblazoned with your choice of three colour decal options (optional extra), 303 Firecrest wheels are as alluring as they are easy to use. And should you choose to run tubed tyres, the new 303 is fully compatible.
Durable Carbon Layup
A new carbon fibre layup keeps weight low while maintaining the 303’s legendary durability. The rim’s lightweight design allows the 303 to glide up the steepest climbs while their robust 77D front hub, paired with 24 Sapim® CX-Ray spokes, keep the wheel stiff and responsive. To ensure compatibility with any bike, Zipp's versatile 77D hub comes with swappable end caps to work with QR’s and thru-axles, including 12x100mm and 15x100mm front thru-axles. And like all Zipp carbon wheels, the new 303 Firecrest is laid up, moulded, drilled and assembled in Indianapolis, USA.
Built to take you to places you’ve never been, the 303 Firecrest® Tubeless Carbon Cincher will go the distance. It’ll just take less time.
