Following the success of the 808 NSW, which was ridden to victory at the Pro Men’s Ironman World Championships and the Elite Women’s UCI Team Time Trial World Championships, Zipp is proud to launch their second wheelset in the NSW Series, the Zipp 404 NSW Carbon Clincher. Zipp's advanced development engineers in their top-secret lab, known as The Nest, have delivered a wheelset with improved braking performance, exceptional aerodynamic efficiency, and unparalleled crosswind stability with the most popular and best-selling rim depth. Like the 808 NSW, the 404 NSW also makes use of a Cognition hubset for increased durability and exceptionally low freehub drag. No matter where you ride, the 404 NSW is engineered to make that ride faster. With a rim depth of 58mm, the 404 NSW is designed as a do-everything wheelset that is adept at climbing and maintaining speed on the flats; a wheel strong enough to handle the Spring Classics, but light enough to inspire sprints out of corners. With its advanced aerodynamics, developed using 42 different CFD (Computational Fluid Dynamics) concept studies and months in the wind tunnel, the 404 NSW’s unrivaled crosswind stability saves watts that would have been spent keeping the bike straight, and provides unequivocal confidence for high speed descending. When it comes time to slow for a corner, the NSW-exclusive Showstopper brake track stands ready to deliver the best modulation and shortest stopping distances available, regardless of weather conditions or the length of the descent. Simply put, the 404 NSW represents the cutting-edge of carbon clincher wheel technology delivered straight from The Nest, where Zipp’s advanced development engineers design the world’s fastest wheels.

Feel your bike come alive on the open road with the new Alpinist CL II, featuring the lightest, best-handling clincher rims we have ever made, elevated with the performance of a tubeless system. The brand new Alpinist CL II now brings mountain-taming performance slightly closer to earth with a carefully selected build designed to let riders take full advantage of the low rim and spoke mass. The Alpinist CL II utilizes the same rim as the alpinist clx ii. They react to even the slightest increase in power with immediate acceleration and carve the purest lines in the corners, yet they can also handle almost double the impact standards of every certifying body. The result is a 1375-gram tubeless wheelset with an otherworldly ride quality designed for real-world road pressures. The Alpinist CL II utilizes components curated to keep you rolling and rolling fast. The DT Swiss 350 hubs, featuring their star ratchet drive system, are reliable and easy to service, while 24 DT Swiss comprace straight-pull spokes front and rear, laced to the rims with their alloy pro lock nipples, are synonymous with reliability and can be obtained at any bike shop. The reduced rolling resistance of a tubeless setup is undeniable, as are the benefits of improved handling and incredible puncture protection. It took the most extensive and demanding engineering and testing program we've ever undertaken. As a result of this extensive development, the Alpinist CL II features a hooked rim that can handle a huge range of pressures up to 110psi and offers an easier set up and mounting experience than ever. - Rim: Alpinist CLX Carbon Clincher, 700c, Disc Brake, Tubeless - Rim Details: 33mm Depth, 27mm External Width, 21mm Internal Width - Hub: DT Swiss 350 Straightpull Center Lock, Star Ratchet 36t internals (10 degs), 100x12mm & 142x12mm, Shim.

Following directly in the tire tracks of the Terra CLX, the new Terra CL utilizes the same super-light, incredibly tough rim as our flagship wheel. It's a hook-bead, 33mm deep carbon fiber rim with a 25mm inner width that plays well with tubeless setup and allows you to mount tires anywhere from 28mm to 47mm wide at whatever pressure you feel like running. In a nod to accessibility, durability and real-world serviceability, we opted to use ultra-dependable DT Swiss 350 hubs and lace them to the rims with DT Swiss Competition Straightpull spokes. The net effect of these changes is a wheelset that is almost as light as our incredibly light Terra CLX, offering close to the same benchmark performance but with more easily sourced spokes in the event of some back-of-beyond carnage, all with a price tag that is about half that of our flagship product. - Rim: Terra CLX Carbon Clincher, 700c, Disc Brake, Tubeless Compatible - Rim Details: 32mm Depth, 30mm External Width, 25mm Internal Width; ERD 577mm - Hub: DT Swiss 350 Straight-pull Center Lock, Star Ratchet 36t internals (10 degs), 100x12mm & 142x12mm, Shim.

At the helm of taking traction, stability, speed, and stiffness to new heights stands the Roval Traverse Fattie 38 650b wheels with 110mm front and 148mm rear hub spacing. And while their Boost-spacing axle widths give the frame and fork clearance and stiffness that results in a stiffer, stronger, and more durable system at a minor weight penalty, what turns them into descending machines is the 38mm internal rim width. The reason behind this is relatively simple: aside from the lightweight, ultra-rugged E5 alloy construction, the combination of the revolutionary width with wider hub flanges equates to an increase in plus-sized tire volume for more suppleness in the ride quality. Not only this, but the ample width also better supports the tire, meaning that you'll experience less "burping" when riding tubeless, as well as a drastic increase in traction. These aren't just a one-trick pony, however. At the front hub, you'll get a 15x110mm thru-axle (end cap options included), and at the rear, the 148mm hub features DT Swiss internals for lightning-fast engagement and acceleration. And to top everything off, these wheels are hand-built to ensure the perfect tension and a long lifespan. Whether you have just picked up a new plus-sized 650b bike, or you're curious to try out three-inch tires on your Boost- spaced 29er, the Traverse 38 Fattie 650b wheels will leave you impressed after the first spin. - Rim Type: Alloy clincher, Zero Bead Hook design, 2Bliss Ready - Rim Material: E5 high-strength alloy - Rim Width: 38mm internal - Front Spoke Pattern: Radial/Three-cross (2:1) - Rear Spoke Pattern: Three-cross (1:1) - Spoke Count: 24-hole Front, 28-hole Rear - Spoke Type: DT Swiss Revolution - Nipple Type: DT Swiss Pro Lock hexagonal - Front Hub: alloy body, 15x110mm thru-axle only—15mm end caps included - Rear Hub: CNC-machined alloy body, high-quality DT 360 internals, includes SRAM XX1 11-speed freehub and 148 end caps - Compatible with Shimano 10- and 11-speed freehub bodies—sold separately. - Bearing Type: Sealed cartridge - Assembly Method: Hand-built - Total Wheelset Weight: 1870g - No rider weight limit.

CZR i23 gravel wheels are designed to minimize weight while blending stiffness and compliance to maximize power transfer and increase comfort. CZR i23 rims feature a 24mm section depth to maximize energy transfer, reduce weight, improve vertical compliance, and reduce rider fatigue while a hooked bead also improves tire retention with high-pressure adventure road and gravel tires. CZR I23 CARBON RIMS Reinforced spoke beds improve overall wheel strength and durability while also minimizing weight in areas where less strength, and therefore material, is needed. CZR i23 rims feature 3mm of asymmetrical spoke offset and a 24mm section depth to improve radial stiffness and maximize energy transfer without being affected by crosswinds like other wheels with deeper profiles. SOLID STRIP & TCS TAPE Durable nylon strip that lies between the rim and tubeless tape to prevent tubeless tape from pushing into the spoke holes and ensures a smooth interface between the tire and rim. The smooth surface makes it easier to mount a tire by preventing air from escaping around the bead at each indent during inflation. Solid Strip also protects the airtight system from puncture in the case of a broken spoke. 2-CROSS OR 3-CROSS LACING CZR i23 gravel wheels with 24 spokes feature a 2-cross lacing pattern to increase radial stiffness and decrease weight. CZR i23 wheels with 28 spokes feature a 3-cross pattern to increase durability while still providing ample radial stiffness due to the additional spokes. FREQUENCY HUBS The world's best carbon rims deserved to be paired with high-quality hubs that further improve the performance of a lightweight, dependable carbon wheelset. Frequency hubs feature a low-drag, 6-pawl design that alternates contact between two sets of 3-pawl groupings to provide a responsive 5 degrees of freehub engagement. Frequency hubs laced to CZR i23 wheels feature lightweight pawl springs that minimize drag and therefore improve efficiency for drop-bar usage. AERODYNAMIC WING SPOKES Pillar racing spokes that are cold-forged into an aerodynamic wing shape that reduces drag at the trailing end of each spoke. As a result, wing spokes improve overall efficiency while still retaining the gram-conscious weights of traditional bladed spokes. SAPIM ALLOY NIPPLES All CZR i23 wheels feature time-tested Sapim alloy nipples to further reduce overall wheel weight while still exceeding the durability requirements of gravel. Countless Configurations CZR i23 wheels are available in a 24-spoke option for riders looking to minimize weight and increase compliance, while the 28-spoke versions are best for heavier or more aggressive riders who prioritize stiffness and durability. All CZR i23 wheels are available with Centerlock or 6-bolt rotor mounts. CZR i23 front wheels use a 12x100mm Frequency hub, but 15mm end caps are also available separately. Why Choose CZR i23?
