Roadies all drool over carbon wheels, but the price tag often puts them out of reach. The new C 38 Disc wheels break down this barrier while bringing reliable, high performance carbon road wheels to the masses. With the C 38, we developed an all-new, lightweight, and durable carbon rim with the modern features that savvy riders demand, and then we paired it with trusty DT Swiss components, like DT 350 rear hub internals and Competition spokes, for a build that ticks all the boxes on your wish list. The new C 38s are the perfect depth (38mm), too, so they'll feel at home on everything from gravel bikes, to aero bikes, and everything in between. - Assembly Method: Hand-built - Braking Surface: Disc brake only - Extras: Roval tubeless tape and tubeless valves - Front Hub: DT Swiss 350 Disc for Roval, 100x12mm, Center Lock - Front Spoke Pattern: Two-cross/Radial - Nipple Type: DT Swiss Pro Lock Brass hexagonal - Rear Hub: DT Swiss 350 Disc for Roval, 142x12mm, Center Lock, 11-speed - Rear Spoke Pattern: Two-cross/Two-cross - Rim Depth: 38mm - Rim Material: Carbon - Rim Type: Carbon clincher, 2Bliss Ready - Rim Width: 21mm internal, 26.6mm external - Spoke Count: 24 front, 24 rear - Spoke Type: DT Swiss Competition Race J-bend - Total Wheelset Weight: 1,560g

Performance Upgrade Made Easy The C38 brings carbon fiber high performance to the real world. It's a versatile all-rounder equally at home crushing gravel washboards and summiting alpine passes. Optimized for use with modern wide tires, providing the right amount of sidewall support to facilitate surefooted handling in all conditions, the C38 wheelset is a great handling, lively climbing, robust all-road performer that also aerodynamically outperforms many deeper, aero-specific rims that cost twice as much. Carbon wheels are a true performance upgrade to any bike, but too often the price tag puts them out of reach. The Rapide C38 shatters that barrier and brings a class-leading Roval carbon rim and DT Swiss reliability together to provide riders with the best performance carbon wheel per dollar.

Since 2020, Rapide CLX wheels have won more races on the world tour than any other wheels, and we just made them faster. Meet the new Rapide CLX II. Combining the aerodynamics of a deep-section TT wheel with the light weight of a shallower climbing wheel and mixing in the superior efficiency and sublime handling of a tubeless system-the Rapide CLX II delivers maximum speed for real-world riding. We developed distinctly different shapes for the Rapide CLX II front and rear rims. The result is a wheelset that catches less drag than most 65mm wheelsets and brings a dramatic 25% improvement in stability over 50mm rims in wind gusts. The Rapide CLX II utilizes a hooked rim (allowing for real-world riding pressures up to 110psi, if that's your thing) for secure tire bead retention and an easier set up and mounting experience than ever before. All in a wheel that almost doubles current industry impact standards while managing to achieve the lightest weight possible. Our aeroflange hubs are aerodynamically optimized, with wide bracing angles for increased strength and reduced spoke weight. They also benefit from the reduced weight and increased strength of ceramic sinc bearings and the legendary durability of DT Swiss exp freehub internals. - Rim: Rapide CLX Carbon Clincher, 700c, Disc Brake, Tubeless Rim Details: 51mm Depth, 35mm External Width, 21mm Internal Width - Hub: Roval Aero Hub (AFD01/AFD02R) Center Lock, DT Swiss 180 Ratchet EXP 36t internals (10 degs), 100x12mm & 142x12mm, Shim.

Zipp's 303 S Tubeless Disc Brake wheelset provides today's cyclists the versatility they demand with the speed they crave. Expanding greatly on its heritage of conquering the Spring Classics, this 303 wheelset maintains its ideal-for-every-terrain 45mm rim depth but adds a significantly wider internal width to provide greater performance and ride quality in almost every measurable way. This wheelset is tubeless for disc-brake bikes, allowing the ability to run wide tires at lower pressures for race-ready speed on or off the pavement. The 303 S is among our lightest wheelsets, optimized for top aero performance with a 28mm tire but capable of handling gravel tires up to 50mm wide. - Wide rims optimize tire profile to allow lower tire pressure, especially with tubeless. The result is a larger contact patch for increased grip and confident cornering, descending, and handling in wet conditions. - Lower tire pressures and larger volume provides a compliant ride with fewer vibrations. - Significant watt savings when running larger tires at lower pressure. - Wide, hookless rims create a seamless transition to the tire, reducing drag. - Fastest with 28mm, but fits wide gravel tires as well - New Zipp graphics and cosmetic identity that scream speed

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. Its Axial ClutchV2 technology reduces drag and lowers friction - Ships with 12mm end caps - Center Lock rotor interface. Lockring is included - Zipp graphics applied using Zipp's ImPress direct-print technology - Lifetime warranty
