The Zipp 202 NSW is crafted with the climbing specialist in mind - bringing weightless speed to the steepest of grades, empowering riders to reach the summit faster on our lightest wheelset ever. However, the 202 NSW does more than climb fast; it provides aero advantage for the race to the climb and is designed for confidence on the getaway descent. Building on the carbon layup found in the state-of-the-art 353 NSW, the 202 NSW features our Biomimetic Laminate which utilizes mixed-modulus carbon types to maximize stiffness at the spoke bed and toughness at the tire bed, mimicking the function of a muscle tendon. The carbon fibers selected for the outer diameter of the rim prioritize strength and durability to withstand impacts from the road, while the inner diameter of the rim uses higher modulus fibers to maintain consistent spoke tension under dynamic riding loads. The result is a rim design that allows for a sub-1100-gram wheelset that reacts to your every input without sacrificing durability and the aerodynamic advantage of its 35mm rim depth on the descent.
Features
- German-engineered ZR1 SL hubset with lightweight Alpina Hyperlite spokes in a 20-hole 2-cross configuration
- Ultra-corrosion resistant ceramic bearings and 66 points of efficient engagement, ensuring every watt is transferred smoothly to the road as you rise to the challenges ahead
- 35mm rim depth
- Weighs in at just 1090 grams
- 23mm inner rim width
- Lifetime Warranty

Overview The Zipp 303 XPLR S is big upgrade for gravel riders without a big price tag. This wheelset borrows key innovations from our premium wide gravel wheelset, it is affordable and robust for discerning gravel riders. This wheelset is the fastest on gravel, thanks to its mega-wide rim that integrates seamlessly with approved gravel racing tires.* In gravel, resistance and vibrations from bumpy surfaces create a barrier that slows riders down. To combat this, Zipp applied Total System Efficiency specifically to the challenges of gravel. The wide profile increases air volume, allowing for lower tire pressures without squirm. That means you mitigate surface vibrations while maintaining grip when cornering or traction while climbing. The rim profile also creates a seamless transition with gravel tires for unsurpassed aero efficiency on gravel. And while the 303 XPLR S is built big, it’s light to keep you fast and fresh for those long, fulfilling days in the saddle. The Zipp 303 XPLR S is compatible only with approved tires. Features - Fast and robust gravel wheel, features tubeless and hookless rim profile - Ultra-wide internal profile for decreased rolling resistance, ability to run pressures under 30psi (2.1 bars) - Wide and deep profile integrates seamlessly with gravel tires to increase aerodynamic efficiency - Applies Zipp’s Total System Efficiency to high-performance gravel - Ships with 12mm front and rear end caps - Max tire pressure 50 psi/3.45 bar - Lifetime Warranty * 303 XPLR S IS ONLY COMPATIBLE WITH APPROVED TIRES.

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 wheel yet, making it a fast-puncher ready to fight its way into the breakaway. Zipp's use of hookless (straight side) rims 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.
