Zipp s 353 NSW Tubeless Disc-brake wheelset is the pinnacle of our pursuit of versatility and speed. This wheelset fuses Zipp s two most advanced approaches, Sawtooth rim profile and Total System Efficiency for an all-encompassing approach to performance. Zipp's lightest tubeless ready wheelset yet at just 1255g per pairSawtooth rim with Hyperfoil nodes and HexFin ABLC dimple pattern for top aero and crosswind-stability performance with an undulating rim depth25mm internal width and tubeless compatibility for optimization of wider tyres with lower tyre pressureCognition DB hub set with Axial Clutch freehub rolls efficientlySuitable for 100x12mm (front) and 142x12mm (rear) axles - sold individually as front or rear wheelsWith its undulating 45-mm 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. With Zipp s hookless rims, 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 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 wheelset s 25mm internal width is ideal for running wider tubeless tires at reduced air pressure for a more efficient ride. At the centre 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.

Wider Carbon Fibre Rim for Better Aerodynamics The 303 Firecrest Tubeless Disc brake wheels were designed using real-world direct measurements (vs. primarily wind tunnel or computer simulation). This included Zipp’s RollingRoad™ Testing Protocol. The results were huge. Its rim is slightly more bulbous in design than its predecessor, with a 30mm outside width, a 25mm internal width and a 40mm rim depth. The profile provides low drag and an improved transition between rim and tyre, boosting aero efficiency on the road. Faster Performance These wheels are faster, lighter and more capable over varied terrain, whether the surface is tarmac in all its conditions or no tarmac at all. Deeply rooted in Zipp’s drive to conquer the Spring Classics, the revised 303 Firecrest is redesigned with a purpose-made approach for the demands of modern road bikes. This is the first Zipp wheelset to feature TSE™ Technology (Total System Efficiency). The 303 Firecrest’s precise rim layup results in greater all-around efficiency for greater speed through reduced wind resistance, rolling resistance, a lower weight, increased durability and vibration losses. More Comfortable Ride on Mixed Terrain The wide rim stance also features less tyre deflection for reduced rolling resistance. The combination of the wider tyre, increased tyre volume and lower tyre pressure reduces rider fatigue. This is because the ride is smoother over imperfect surface conditions as the tyre and wheel system absorbs the shaking, not the rider. At the centre of the 303 Firecrest Tubeless Disc brake is a versatile and durable hubset, the German-engineered ZR1 DB. This hubset features 66 points of engagement for quicker pedalling response. The 303 Firecrest Tubeless Disc-brake wheelset is for those after greater efficiency for greater speed. The payoff is a smoother, faster ride. Additional Features: Updated Zipp graphics and cosmetic identity that scream speed Versatile endurance wheelset for the modern road bike with tubeless and hookless rim profile Lower in weight - a 300g weight reduction than its predecessor, making it nimble and fast Tubeless Made Easy, optimised tyre bed sign allows for simple tool-free installation and removal with no need for an air compressor to seat the tyre Ultra-wide 25mm rim profile creates a better tyre interface to be fast on or off the road 40mm rim depth makes a light and aero wheel in every situation ZR1 DB hub is engineered in Germany with better seal design for improved durability and quicker response with 66 points of engagement Ships with 12mm front and rear end caps Centre locking rotor interface Lockring is included with the wheels Lifetime Warranty

The 454 NSW Tubeless Disc brake wheelset is roughly a pound (more than 400 grams) lighter than its predecessor! Zipp s use of hookless (straight side) rims in the 454 NSW is integral to making you faster. With hookless, the transition between the tyre and the rim is more seamless and aero. Zipp s hookless rims have more efficient resin distribution, which means lighter, stronger wheels. Outdoor testing commissioned by Zipp revealed the real-world gains of Zipp Total System Efficiency (TSE). A bike-and-rider system weighing 85kg (187lbs) on the new 454 NSW with 25mm tyres required 278 watts to maintain a speed of 40kph. That s a 10-watt savings compared with the previous model 454 NSW. At the centre of the 454 NSW is the Cognition V2 hub set re-engineered with an updated Axial Clutch V2 mechanism for quicker engagement, lower friction, and improved durability.
This all-new carbon wheelset is a great choice for road riders aiming to be fast and efficient in all types of riding and racing situations. Not only does the 45mm airfoil rim slice through the wind with minimal drag but it’s also amongst the lightest in its category. This season the external carbon layer features our new UD² construction for a distinctive look and an even lighter rim laminate saving another 15g per rims.A new rim laminate coupled with our exclusive Fore Carbon technology leaves the upper rim bridge intact and reinforces the rim only where needed saving 40g per rim. The spokes attach to the rim without any need to drill the upper rim bed so no rim tape is required. That means more weight savings (30g) and less hassle when it comes to set up or repair tubeless tyres. The new shape of the rim bed makes it easier than ever to mount and remove tires. UST Tubeless setup means no tube so no friction and more air volume means a smoother ride. The result is a faster ride with super low rolling resistance.
