Zipp s go-to triathlon and time trial weapon, the Super-9 Tubeless Disc rim-brake wheel is tubeless ready with a 18mm internal width.New Zipp graphics and cosmetic identity that screams speed applied with our ImPress direct-print technology18mm internal width and tubeless compatibility for optimisation of wider tyres with lower tyre pressure, lower rolling resistance, and increase grip and complianceGreater stopping power and modulation of disc brakesAero, durable, light weightCentre locking rotor interface. Lock ring is includedXDR or SRAM/Shimano driver bodiesCampagnolo driver body sold separatelyThat means you can lower tyre pressure for a host of benefits: better cornering grip, better compliance, and reduced rolling resistance. With tubeless, you get all this without the risk of pinch flats. So, go attack the course. The Super-9 gives you the technology needed to do your best. The Super-9 Carbon Clincher optimizes supreme aerodynamics, power transfer, stiffness, lightweight and durability. Add to that the modulation and stopping power of disc brakes, you re ready to set that PR.
Zipp s 303 Firecrest Tubeless Disc-brake wheel is designed for the real world a world of imperfect conditions, road surfaces, and elements where the bottom line is simple. Efficiency = speed. It s faster, lighter, and more capable over varied terrain, whether the surface is pavement in all its conditions or no pavement at all. New Zipp graphics and cosmetic identity that scream speedVersatile endurance wheel for the modern road bike with tubeless and hookless rim profileLighter Weight 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 roadNew 40mm rim depth makes a light and aero wheel in every situationNew ZR1 DB hub is engineered in Germany with better seal design for improved durability and quicker response with 66 points of engagementShips with 12mm front and rear end capsCentre locking rotor interface. Lock ring is included with the wheelsXDR or SRAM/Shimano driver bodiesCampagnolo driver body sold separatelyDeeply 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, weight. The 303 Firecrest Tubeless Disc-brake was designed using real-world direct measurements (vs. primarily wind tunnel or computer simulation). 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. 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 helps to reduce rider fatigue by smoothing out the ride over imperfect pavement and road conditions 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 new hub, the German-engineered ZR1 DB. This hub features 66 points of engagement for quicker response. The 303 Firecrest Tubeless Disc-brake wheel is for dedicated cyclists who aspire to the latest in technology. Its competitors in races, against peers, or simply conquering personal limits. This is about becoming faster and matching your motivation to the most advanced technology.Orientation (wheels): RearSize (wheels): 700cRim construction: CarbonTire compatibility: Clincher Tubeless ReadyRim depth: 40mmSurface texture: ABLC SawToothBrake compatibility: Disc (Center Lock)Rim - inside width: 25mmRim profile: SymmetricalRim finish: UD fiber, adhesive decalsColor (Decal): StandardNipple material: AluminumNipple anti-rotation: Sapim Secure-LocSpoke type: CX-SprintSpoke count: 24Spoke pattern: 2 CrossHub: ZR1 Disc BrakeDriver body type: SRAM/Shimano Road or SRAM XDRColor (hub): BlackAxle type (Wheels): TA 12x142Axle material: Aluminum front & rearBearings: Cartridge - Stainless SteelDriver Mechanism: 6 Pawls Leaf SpringDriver body material: AluminumMax tire pressure: 73psiMax recommended rider weight: 250lbsPart Weight (g): 739Please Note: The below tyre brands have communicated to us that their tubeless models are compatible with our tubeless hookless straight side wheels.

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.
