Road bikes are going where they’ve never gone before, are expected to do more, and are being ridden harder than ever. At the same time disc brakes are rewriting the rules of what’s possible with rim design. For this new era, the Zipp 303 Firecrest Tubeless Disc-brake wheelset sets the new standard. With a disc-specific, tubeless rim, the 303 Firecrest Carbon Clincher is now internally 21mm wide and faster than ever. Designed from the start as a tubeless rim, the 303 Firecrest features a rim bed made with internal ridges to lock the tire’s bead in place, ensuring secure performance, even when ridden at lower tire pressures. A new carbon fiber layup keeps weight low while maintaining the 303’s legendary durability.

Zipp makes the impossible possible with their 303 Firecrest Carbon Disc Brake wheels—they're equally at home on the flats as they are in the mountains. The 45mm-deep rims slice through the wind more efficiently than even many deep-section wheels thanks to their 28.5mm-wide dimpled rims. And, by creating a seamless junction between rim and tire, the increased width further reduces drag. The 303s climb with the best and re-accelerate out of corners like rockets since they barely register on the scale, which makes them a must-have on undulating terrain. The extra wide rim also allows running wider tires at lower pressures with less fear of pinch flatting, which boosts ride quality and comfort and reduces rolling resistance. Plus, Zipp's 77D/177D disc hubs gives you incredible stopping power in wet and dry conditions alike, and they're thru-axle compatible (sold separately) for jaw-dropping steering precision and power transfer. You also get Sapim's oustanding CX-Ray spokes.

Zipp hits high all-around marks with their 303 Firecrest Tubular wheelset, thanks to a wide tire bed and mid-aero profile. The 28.5mm rim width provides confident control in nasty crosswinds and on rough roads, and the 45mm Firecrest rim profile offers wind-shedding aerodynamics while maintaining great acceleration characteristics. Zipp's 77/177 hubset, laced with Sapim CX-Sprint spokes, provides maintenance-free reliability and lateral stiffness, and trusted stopping power comes via Tangente Platinum Pro Evo brake pads. Included with each wheel are a Zipp-integrated Valve Extender with valve-core wrench, rim tape, and quick release.

Zipp optimized its Firecrest technology to build a highly aerodynamic 82mm rim—the 808 Firecrest Tubular Disc Brake. Designed for efficient power transfer and stable control in time trial and triathlon competition, the 808's wide 27.5mm rim shape provides confident tracking in crosswinds and over rough surfaces. Built with Zipp's excellent 77/177 hubset that features optimized flange geometry and Sapim CX-Sprint spokes to increase lateral stiffness, this 1,1885-gram wheelset combines toughness and reliability in a wind-shedding package that has to be ridden to fully appreciate. Each wheel includes specially-designed Tangente Platinum Pro Evo brake pads, Zipp Integrated Valve Extender with valve-core wrench, rim tape, and quick release.

Zipp’s first product almost three decades ago was a disc wheel. It’s at the heart of their heritage. Now, Zipp is pioneering the next generation of disc wheel, the Super-9 Disc-brake Disc. The Super-9 Disc itself, handmade at Zipp's factory in Indianapolis, USA, optimizes supreme aerodynamics, power transfer, stiffness, lightweight and durability.The Super-9 disc has an unassuming profile. It borrows from the perimeter shape that makes the Sub-9 so fast it can actually generate forward lift, but in place of the Sub-9's toroidal bulge, the Super-9 remains flat from its widest point all the way to the hub. This relatively simple-looking shape results in a wheel that's as fast as the Sub-9 but stiffer than any other Zipp disc. Braking on modern time trial and triathlon bikes often has been a challenge. The superior performance of disc brakes changes all that with greater stopping power and more precise speed modulation, all with less hand effort than required by traditional brakes. That means greater confidence in corners, descents, and on technical courses. The disc brake version of the Super-9 disc retains the light weight of its rim-brake counterparts. - Includes: Aero Stainless Steel Black Quick Release, 10-speed hub spacer, Platinum Pro EVO Brake Pads, Valve Extender, Valve Adaptor, Valve Decal

Equip yourself with the wheel that carried Tony Martin to a World Championship and reach the pinnacle of your own potential. Zipp’s Super-9 Carbon Clincher Disc underwent extensive fluid dynamic modeling, wind-tunnel testing, and relentless refinement so you can enjoy no-holds-barred aero domination. With a variance in width of just a single centimeter from rim to hub, the Super-9 is almost invisible to the wind. Plus the wide rim creates a virtually seamless integration with the tire, increasing aerodynamics and allowing wider tires run at a lower pressure. This diminishes rolling resistance, increases rider comfort, and reduces the chance of pinch flatting.
