Zipp's 353 NSW Tubeless Disc-brake wheel is the pinnacle of our pursuit of versatility and speed. This wheel fuses Zipp's two most advanced approaches, Sawtooth rim profile and TSE, for an all-encompassing approach to performance. With its undulating 45mm-deep rim shape, the 353 NSW provides speed on every terrain with best-in-class aerodynamic efficiency and crosswind stability. The 353 NSW is Zipp's lightest tubeless wheelset yet, making it a fast-puncher ready to fight its way into the breakaway. Zipp's use of a hookless (straight side) rim in the 353 NSW is integral to achieving our mission of Making You Faster. With hookless, the transition between the tire and the rim is more seamless and aero. Zipp's hookless rims have more efficient resin distribution, which means lighter wheels. They also are highly durable. Zipp's 353 NSW's Sawtooth rim shape with Hyperfoils optimizes aerodynamic efficiency and crosswind stability. The Sawtooth design also allows the rim to be structurally strong but light. That will help you snap out of corners and maintain that speed no matter the terrain, especially in the steep, punchy stuff. The 353 NSW utilizes Zipp's Total System Efficiency, or TSE, approach to wheel design: overcoming specific barriers to speed: wind resistance, gravity, rolling resistance, and vibration losses. The wheel's 25mm internal width is ideal for running wider tubeless tires at reduced air pressure for a more efficient ride. At the center of the 353 NSW is the Cognition V2 Hubset, re-engineered with an updated Axial Clutch V2 mechanism for quicker engagement and lower friction, as well as improved durability. - Versatile endurance wheel for the modern road bike with tubeless and hookless rim profile - Our lightest tubeless wheel yet, making it a fast-puncher ready to fight - Optimized tire bed for easy tire installation - TSE for greater efficiency and reduced rolling resistance - Sawtooth rim with Hyperfoil nodes and HexFin ABLC dimple pattern for top aero and crosswind-stable performance with an undulating rim depth - Cognition V2 hubset rolls efficiently whether you are pedaling or coasting.

What It Is The G23 is the definition of a true gravel wheelset. At 330 grams, ENVE's lightest 700c tubeless rim accelerates quickly and ascends with ease. Armed against pinch flats with the patent-pending Wide Hookless Bead, the G23 is tough and relentless on road, path, or trail. The G23 is a 700c tubeless carbon clincher wheelset with a generous 23mm internal width, specifically conceived to meet the performance and ride quality demands of serious mixed-surface cyclists. Who It's For Created for those seeking to discover new experiences, new terrain, and new challenges. Built to reflect the versatility of today's gravel and mixed surface riders, these wheels will excite ambitious, daring, and indomitable riders everywhere. If your path leads to classics like Dirty Kanza, Landrun, Crusher in the Tushar, or a new wave of events like Grinduro or Lost and Found, the G23 is your wheel. Why We Made It There is a place between road and mountain that is open to discovery. Beyond the range of your trail bike or the capabilities of your road bike. Terrain littered with contradicting challenges and demanding requirements are at odds with the bikes and products available today. We built the new G23 to thrive in this new environment, because insights gained through building the world's best road and mountain bike rims told us that the perfect combination did not exist in our stable, or in our opinion, anywhere at all. The higher volume and lower pressures would demand MTB toughness and flat resistance, while big days and long miles would require the lightweight and efficiency of a road machine. Above all, the combination of rough and rigid would require a wheel with the ride quality to make those long miles enjoyable and multi-day treks possible.

What It Is A purpose-built XC wheelset without limitations. Light enough to race, strong enough to ride daily. Reduced fatigue and a more compliant ride through shape, laminate, and spoke-hole optimization. Who It's For Modern XC racers and riders who demand equal uphill and downhill performance, light weight, durability, and vertical compliance for long hours in the saddle. Why We Made It Carbon fiber is responsible for unlocking the potential of bigger and wider tires on mountain bikes. Today, riders can improve comfort, efficiency, and control by adapting their mountain bikes perfectly for the terrain and trails. Undoubtedly, this means they can go further and faster with more confidence. Complement increased tire volumes and rim widths with a modern XC tread, and you've got an effective system, maximized for the variable-pitch trail. The result is a purpose-built full-carbon fiber XC wheelset that is lighter, wider, and more vertically compliant without sacrificing strength or reliability. Additionally, the M525 features ENVE's patent pending, wide hookless beads that improve pinch flat resistance and allow riders to run modern lightweight XC tires with a reduced risk of pinch flatting or impact damage.

Versatile, aero, light, and fast. The SES 3.4 has been a staple in the SES wheel family, and the newest iteration takes the best features of the previous generation SES 3.4 and 3.4 AR to make the ultimate modern road wheelset. There’s simply nothing more versatile than the SES 3.4. - Carbon fiber consctruction using continuously running fibers throughout the rim, tapering laminates, and removing excess material - 38mm front and 42mm rear rim depths maximize aerodynamic efficiencies, reduces weight and manage crosswind riding conditions with ease - Hookless bead tubeless technology reduces weight, improves comfort, maintains strength, and ensures an exacting rim bead seat - Premium Road Hubs bring efficiency, longevity, and simplicity: Cold-forged and machined 6061 alloy for durable lightweight performance - Tubeless and disc brake only

What It Is The ultimate disc brake-specific, aerodynamic, lightweight road race wheelset. Who It's For The SES 5.6 Disc is optimized aerodynamically and structurally for disc use. Road cyclists and triathletes on disc brake bikes will benefit from the SES 5.6 Disc's reduced drag, lightweight design, and rim shape optimized for larger-volume road tires. Why We Made It Most "disc brake" wheelsets are simply repurposed rim brake wheels with disc hubs. The elimination of a braking surface opens up the realm of aerodynamic and structural possibilities. When you don't have to engineer a flat braking surface and manage high temperatures from braking, you can reduce the rim's weight, adjust shape for improved aerodynamics and provide better tubeless performance. Full Details Disc brake technology offers improved braking performance for amateur and professional road cyclists alike. Carbon fiber braking surfaces are a major design constraint that limits weight savings and rim design. By removing the constraints of a braking surface, we can completely rethink the shape of the rim. The SES 5.6 Disc features patented SES rim curvature, but has been further optimized for disc brakes. Additionally, the SES 5.6 Disc carbon fiber clinchers and tubulars are very lightweight, because the material used for rim brake heat management has been eliminated. This allows for a more structurally efficient and impact-resistant rim. Finally, the SES 5.6 Disc carbon clincher is road tubeless-compatible and can still be run with standard inner tubes and tires. Like the current generation SES carbon clinchers and tubulars, the 5.6 Disc has been aerodynamically optimized around 25mm tires.

Zipp's 303 Firecrest Tubeless wheels are designed for the real world—a world of imperfect conditions, varying road surfaces, and elements where the bottom line is simple: efficiency = speed. They're faster, lighter, and more capable over varied terrain—whether the surface is pavement in all its conditions or no pavement at all. Deeply rooted in Zipp's drive to conquer the Spring Classics, the new 303 Firecrest is remade with a purpose-made approach for the demands of modern road bikes. When it comes to going fast on a bicycle, efficiency means reduced wind resistance, rolling resistance, rider fatigue, and weight.
