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. The rim’s lightweight design allows the 303 to glide up the steepest climbs while SRAM's robust 77/177D hubset keep the wheels stiff and responsive. Each Wheel Includes: - Zipp Tubeless valve extender and valve-core wrench - Zipp rim tape (factory taped) - Zipp Tangente quick-release skewer - Zipp thru-axle end caps

Zipp's 3ZERO MOTO carbon enduro/trail wheels are inspired by moto to provide riders with the control and durability required for pure speed. Moto remains a powerful source of inspiration for good reason. Based in the racing hotbed of Indy, Zipp for more than three decades has used motorsports as an inspiration to develop pioneering carbon cycling innovations. Our single-wall approach, what we call Moto Technology, allows the rims to "pivot" from either side of the spoke bed while traversing rough terrain. As the wheel encounters obstacles, each edge of the rim is designed for compliance, creating the feel of extra suspension. For the rider, that means durability and control for greater speed. Moto Inspired. Control + Durability = Speed. - Higher impact resistance - Reduced chance of pinch flatting - More traction in rough corners - More traction in rough corners - Smoother ride in rocky terrain - Ability to run lower tire pressure - Reduced rider fatigue - TyreWiz tire-pressure monitoring device - Frustration-free tire installation - Rim is designed for compliance, creating the feel of extra suspension

If you had to choose just one wheel, the 404 Firecrest Carbon Clincher should be your choice. With the depth and shape proven in all conditions, it’s the all-around performer and the standard by which all other wheels are measured. Its 58mm rim depth is a classic that has carried athletes to victory in every kind of event and situation – every triathlon distance, breakaways, field sprints, and hilly finishes. At the center of the 404 Firecrest is Zipp’s 77/177 hubset with best-in-class durability, bearing protection with no pre-load adjustment needed. The result is improved braking (Showstopper), aero performance, stiffness, durability, simplicity, and versatility. - New, faster, more stable rim profile - AeroBalance - ABLC SawTooth dimples pattern - Showstopper brake track - 10- or 11- speed compatible - XDR option - Handcrafted in the USA

There’s nothing middle of the road about the 808 Firecrest. At 82mm deep, it’s all out aero. Thanks to refinements to Zipp’s revolutionary Firecrest rim shape to be tubeless compatible and optimized for wider tires, the 808 Firecrest Carbon Clincher Tubeless Disc brake is ideal for the new era of disc brake road riding and racing. Without the constraints of rim brake caliper compatibility or brake-track requirements, the Firecrest Carbon Clincher Tubeless Disc-brake wheels offer the increased stopping power and modulation of disc brakes and a whole lot more. To maximize the aero performance of the wheels, Zipp’s ABLC dimples extend all the way to the outer edge of the disc-specific rims. The wheels are also optimized for wider tires to meet the performance needs of modern riders in search of low rolling resistance and aero efficiency with high comfort. The deeper Firecrest Tubeless Disc brake has an internal width of 19mm and are aerodynamically optimized for 25mm wide tires. This design improves Firecrest’s ability to yield low aerodynamic drag and high crosswind stability, a combination called AeroBalance. Designed to be tubeless compatible, the wheels feature 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. Zipp’s low rolling resistance and high grip Tangente RT28 and RT25 Road Tubeless tires pair well with the Firecrest disc brake wheels. A new carbon fiber layup for the Indianapolis-made rims keeps weight low while maintaining the Firecrest Carbon Clincher’s proven durability. The robust 77D/177D hubset, paired with 24 Sapim CX-Sprint spokes front and rear, keeps the wheels stiff and responsive. To ensure compatibility with any bike, the versatile 77D/177D hubs come with swappable end caps to work with QR’s and thru-axles, including 12x100mm and 15x100mm front thru-axles as well as 12x142mm rear thru-axles. The 177D rear hub is also XDR driver body compatible for use with SRAM 10-42 cassettes. Each Wheel Includes: - Zipp Tangente Quick Release Skewer - Zipp Tubeless valve – factory installed - Tubeless rim tape – factory installed - Valve core removal tool - Zipp 77D/177D thru-axle caps to fit 12x100, 15x100 dropouts for front wheels, and 12x142 dropouts for rear wheels - Freehub body spacer – 11 to 10 speed - SRAM XDR driver body for 177D available separately

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.

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.
