Zipp 303 S Carbon Disc Rear Road WheelTaking its design from the higher-spec Firecrest 303 model, this rear wheel is ideal for modern "go anywhere" road bikes. Zipp has also updated this model with a wider rim to improve rider comfort, handling and aerodynamics. Expanding greatly on its heritage of conquering the Spring Classics, this 303 wheel maintains its ideal-for-every-terrain 45mm rim depth. However, this model adds a significantly wider internal width to provide greater performance and ride quality in almost every measurable way. Road bikes are more versatile than ever no matter the road surface, but just as fast as before. The 303 S offers an entirely new rim profile and design to optimise rider performance on this new breed of bike. This wheelset is tubeless compatible and designed for disc-brake bikes, allowing the ability to run wide tires at lower pressures for race-ready speed on or off the tarmac.45mm Deep Rear WheelThe 303 S is among Zipp's lightest wheels, optimised for top aero performance with a 28mm tyre but capable of handling gravel tyres up to 50mm wide. The key innovation is in the 303 S's rim design. Its 45mm rim depth is the same as its predecessor, the 302 Disc brake. But its external rim width is 2mm wider, at 27mm, and its tyre bed is a full 7mm wider, at 23mm internal width. That rim platform is designed to be the fastest with a 28mm tyre. The wide rim optimises tyre profile to allow lower tyre pressure. That helps to reduce rolling resistance and provides a more compliant ride. The result of all this is a 10 watt savings vs. a top peer wheel in total power required to ride 40kph on a flat road with a 28mm tyre, according to internal Zipp testing.This ground-breaking wheel also features all-new cosmetics, setting the rider apart from the pack, and comes at a very attractive price.Please Note: Shimano/SRAM freehub option is for 11 speed Shimano/SRAM XD cassettes. The SRAM XDR freehub option is for 12 speed SRAM XD road cassettes.Features: Rim Material: Carbon Fibre with updated Zipp graphics Brake Compatibility: Disc (centre lock) Rim Inside Width: 23mm Rim Profile: Symmetrical Rim Type: Clincher Rim Finish: UB Fibre / Bake-on Labels / Matte Clear Coat Spoke Type: CX-Sprint Spoke Count: 24 Spoke Pattern: 2-cross Nipple Material: Brass Axle Type: TA 12x142mm Bearing Type: Cartridge - Stainless Steel Driver Mechanism: 3 pawls leaf spring Tubeless Ready: Yes Hub: 176 DB hub with centre locking interface Single or Pair: Single Brake Compatibility: Disc brake Weight: 819gBuy Zipp Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.

Zipp 404 Firecrest Carbon Tubeless Rear WheelZipp's legendary speed weapon, the 404 Firecrest, is better than ever. This go-to rim-brake rear wheel is, for the first time, tubeless ready. That means you can run reduced tyre pressure for reduced rolling resistance and increased cornering grip and compliance without the risk of pinch flats. This rear wheel's 58mm rim depth is a classic that has carried athletes to victory in every kind of event and situation - every triathlon distance, breakaways, field sprints and hilly finishes. Zipp's ABLC Sawtooth Technology uses a complex dimpling pattern to improve aero efficiency. Zipp's ShowStopper textured braking surface delivers unrivalled rim braking performance in wet or dry conditions. At the centre of the 404 Firecrest Tubeless rim-brake is a versatile and durable hub, the German-engineered ZR1. If you had to choose just one wheel for road riding and racing, the 404 Firecrest Tubeless is a savvy and speedy choice.ABLC SawtoothThe Sawtooth dimple design consists of 12 nodes that are specifically clocked to start aerodynamic shearing at a rate of 50hz at a rider speed of 20mph. Sawtooth accomplishes this by inducing small sheet vortices that shed at a low magnitude, but at a higher natural frequency, thus decreasing the laminar bubble effect on the aerodynamically shielded side of the rim's profile to further reduce high yaw drag and improve crosswind stability. ABLC Sawtooth dimple design helps manage air flow around the rim and contributes to creating a faster, more stable wheel.Features: Rim Material: Carbon with UD Fibre finish and adhesive decals Use: Road Axle Type: QR 135mm (quick release) Internal Rim Width: 19mm Rim Depth: 58mm Rim Profile: Symmetrical Brake Compatibility: Rim Brake Size: 700c Tyre Compatibility: Clincher, Tubeless Ready Surface Texture: ABLC SawTooth Nipple Material: Aluminium Nipple Anti-rotation: Sapim Secure-loc Spoke Type: CX-Ray - Black Spoke Count: 24 Spoke Pattern: 2 Cross Driver Body Type: SRAM XDR Axle Material: Aluminium Bearings: Cartridge - Steel Driver Mechanism: 6 Pawls Leaf Spring Driver Body Material: Aluminium Max Tyre Pressure: 125psi Max Recommended Rider Weight: 250lbs Single or Pair: Single rear wheelTechnologies: New Zipp graphics and cosmetic identity that scream speed.

Zipp 404 NSW Carbon Tubeless Rear WheelThe 404 NSW is the ultimate all-rounder and provides fantastic climbing efficiency and comfort while being more than capable of maintaining speed on the flat and stability during high-speed descents. Its stiffness and strength have been proven on the Spring Classic race events across cobbled streets and rough, uneven terrain but are still light enough to inspire rider confidence when sprinting out of corners.CognitionThe ultimate in Zipp hub technology. Every time a conventional hub set starts to coast, friction within the freehub ratchet mechanism works like a drum brake to slow the rider down. The drag between hub shell and driver body during coasting is considered an efficiency loss, especially for road wheels. High drag also can significantly contribute to chain-dropping issues. The drag torque drives the cassette clockwise so the chain gets loose on the load side. The solution? The rear Cognition hub with AxialClutch technology reduces drag by disengaging the ratchet mechanism when coasting. It then uses magnets to re-engage once the rider starts pedalling.ShowstopperShowstopper is a complimenting pairing of a directional, moulded-in, texture with silicon carbide particles suspended in the surface resin. The current media blast process applied to all Zipp rims increases the surface roughness of the brake track providing the rider with consistent and responsive braking. In order to improve this for the wettest of rides, Zipp have introduced a moulded-in groove specifically tuned for the Zipp Tangente Platinum Pro EVO Brake Pad. The grooves have been optimized to interact with leading edge (relative to the rotation of the wheel) of the brake pad and the four cooling channels. The leading edge of the pad and first two channels efficiently wipe water and debris outward, cleaning and drying the braking surface, while the second two cooling channels have maximum interference with the grooves allowing greater braking force than a smooth rim. The cleaning effects of the groove and pad interaction improve brake feel and consistency even in dry conditions.Hexfin Aerodynamic Boundary Layer Control (ABLC)The Sawtooth dimple design consists of 12 nodes that are specifically clocked to start aerodynamic shearing at a rate of 50hz at a rider speed of 20mph.

That's why the brand's wheels are race-ready before they're camera-ready. For years, Zipp has used a combination of testing methods - wind tunnel, CFD computer simulations, pro athlete evaluations, on-road testing, and the RollingRoad ride simulator - to refine aero performance to new levels of excellence. Over the decades of innovation, its engineers have learned to look beyond just focusing on simply reducing aero drag. Instead, the goal now is to reduce aero drag while also minimising the effects of crosswinds on handling. This optimising of aero efficiency and crosswind stability became known internally at Zipp as AeroBalance. The approach began with Firecrest technology and has been advanced with the introduction of the NSW lineup, especially with the Sawtooth technology found in the 454 and 858 NSW. Sawtooth accomplishes this with a series of patented fin-shaped Hyperfoil nodes along the inner diameter of the rim that works together with Zipp's new HexFin ABLC dimples for improved airflow.Features: Rim Material: Carbon with UD Fibre finish and adhesive decals Use: Road Axle Type: QR 130mm (quick release) Internal Rim Width: 18mm Rim Depth: 82mm Rim Profile: Symmetrical Brake Compatibility: Rim Brake Size: 700c Tyre Compatibility: Clincher, Tubeless Ready Surface Texture: ABLC SawTooth Nipple Material: Aluminium Nipple Anti-rotation: Sapim Secure-loc Spoke Type: CX-Ray - Black Spoke Count: 24 Spoke Pattern: 2 Cross Hub: ZR1 Rim Brake Axle Material: Aluminium Bearings: Cartridge - Stainless Steel Driver Mechanism: 6 Pawls Leaf Spring Driver Body Material: Aluminium Max Tyre Pressure: 125psi Max Recommended Rider Weight: 250lbs Single or Pair: Single rear wheel Weight: 1003g (approx)Technologies: New Zipp graphics and cosmetic identity that scream speed.

Wide Carbon Fibre Road Bike Wheel Expanding greatly on its heritage of conquering the Spring Classics, this 303 wheel maintains its ideal-for-every-terrain 45mm rim depth. However, this model adds a significantly wider internal width to provide greater performance and ride quality in almost every measurable way. Road bikes are more versatile than ever no matter the road surface, but just as fast as before. The 303 S offers an entirely new rim profile and design to optimise rider performance on this new breed of bike. This wheelset is tubeless compatible and designed for disc-brake bikes, allowing the ability to run wide tires at lower pressures for race-ready speed on or off the tarmac. 45mm Deep Front Wheel The 303 S is among Zipp's lightest wheelsets, optimised for top aero performance with a 28mm tyre but capable of handling gravel tyres up to 50mm wide. The key innovation is in the 303 S’s rim design. Its 45mm rim depth is the same as its predecessor, the 302 Disc brake. But its external rim width is 2mm wider, at 27mm, and its tyre bed is a full 7mm wider, at 23mm internal width. That rim platform is designed to be the fastest with a 28mm tyre. The wide rim optimises tyre profile to allow lower tyre pressure. That helps to reduce rolling resistance and provides a more compliant ride. The result of all this is a 10 watt savings vs. a top peer wheel in total power required to ride 40kph on a flat road with a 28mm tire, according to internal Zipp testing. This groundbreaking wheelset also features all-new cosmetics, setting the rider apart from the pack, and comes at a very attractive price. Additional Features: Provides today’s cyclists the versatility they demand with the speed they crave Updated Zipp graphics and cosmetic identity Fastest with 28mm, fits wide gravel tyres Wide rims optimise tyre profile to allow lower tyre pressure, especially with tubeless. This results in a larger contact patch for increased grip Lower tyre pressures and larger volume provides a compliant ride with fewer vibrations Significant watt savings when running larger tyres at lower pressure Wide hookless rims create a seamless transition to the tyre, reducing drag 76 DB hub with centre locking interface Lifetime Warranty
