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.

The Podium SRD earned major wins at the B.C. Bike Race and U.S. Marathon National Championships while it was still only in development and stands out as Stan's fastest and lightest racing wheel. Stan's patented BST rim shape has been taken even further by decreasing sidewall height and updating Stan's carbon layup process to shave even more weight where it matters most. Though the 300g Podium SRD rim is Stan's lightest carbon rim, it's every bit as strong as Stan's acclaimed Valor and 15% stiffer laterally, thanks in big part to the evolution of Stan's impact absorbing technology. The new RiACT rim shape and lay up is able to deflect 11% more than the Valor, which translates into fewer pinch flats, added durability, and less rolling resistance. The Podium SRD is laced with Sapim Laser triple-butted spokes and mechanically locking alloy nipples. Combined with Stan's Neo Ultimate hub with updated Speedsync bearing and axle design and near instantaneous engagement, the Podium SRD is purpose built for racing, and ready to live up to its name.

Campagnolo's Bullet wheels bring together the aerodynamic benefit of a deep carbon rim and the consistent braking power and modulation of an aluminum brake track for a best-of-both-worlds scenario that'll propel you one step closer to the podium. Aerodynamic spokes further reduce wind resistance and Campy's impressive G3 rear-wheel lacing pattern drops weight and increases responsiveness for instant-on power transfer. Of course, they're super light and the aluminum hubs are fitted with Campagnolo's legendarily smooth bearings for a practically frictionless ride.

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.

With the T 1800 CLASSIC track style is taken to the streets. From the wide, medium profile alloy rim to the extra flat bladed spokes it oozes muscles. And that muscle is needed when zipping around cars and corners at full pace.

Stan’s S1 wheelset line brings patented tubeless technology to an even wider range of riders. Built for long life, low maintenance, and outstanding value, the S1 series wheels feature 6061 series alloy rims and are available in six different widths suited to a wide range of tire sizes and riding styles. With an emphasis on value and durability, the S1 alloy wheelsets join a mountain wheel line-up that currently includes Stan’s successful MK3 premium alloy wheels and innovative Valor and Bravo carbon series wheelsets. While MK3 wheelsets are built to balance strength, light weight, and stiffness, S1 wheelsets focus on maximum strength and durability. The deeper profile and thicker walls of the S1 rims result in a 50-70g weight increase over MK3 rims, but offer greater impact strength for an even wider range of use. “The new S1 series wheels were developed from rims ridden in Redbull Rampage and raced on the World Cup DH circuit for years,” said Creative Director, Chris Currie. “The goal was to take everything we’ve done for tubeless technology, and put it into a truly bombproof and affordable wheel.” Designed according to Stan’s WideRight rim and tire fit system, S1 series wheelsets are available in six different rim models, with internal widths ranging from 23mm to 38mm. Combined with Stan’s low-profile, high-volume Bead Socket Technology rim design, these widths let the new S1 range accommodate tires from 2-inch to 3.5-inch. All S1 wheelsets are built with 32 spokes front and rear, Sapim’s proven Race spokes, Secure Lock brass nipples, and Stan’s faster-engaging Neo hubs. Hubs are available to fit most axle systems, including Boost. The S1 series includes reinforced versions of the classic Crest, Arch, and Flow--names already familiar to fans of Stan’s tubeless rims. In addition to the Crest S1, Arch S1, and Flow S1, three entirely new wider wheelsets will be available. The Sentry S1, Baron S1, and Major S1 bring Stan’s patented Bead Socket Technology to Plus bikes.
