The new Shamal Ultra from Campagnolo embodies the incredible quality that has made the Shamal the go to aluminium race wheel for almost two decades. Offering further improvements in terms of versatility and performance, and meeting the C17 standard, the Shamal Ultra is perfect for use with 25/28mm tire sizes. Thanks to the Dynamic Balance technology, every point of the rim is counter-balanced by an equal weight on the opposing side, providing maximum stability even at high speeds. The addition of MoMag technology creates a rim profile that is free of holes, making rim tape unnecessary, and the differentiated rim height keeps the spokes in the position of maximum aerodynamic penetration. The toroidal milling reduces the peripheral weight of the rim, making the wheel extremely reactive, the 2-Way Fit profile enables the use of either classic clincher or tubeless tires whilst the Ultra-Fit design allows for easy tire mounting, maximum safety, minimum friction, less energy dispersion and improved performance. The spokes have been designed with an aerodynamic profile to achieve maximum aerodynamic penetration, reducing sag and saving rider energy, whilst the self-locking system ensures that the spokes maintain the optimum aerodynamic position. The spokes are lightweight aluminium with an aero design, and use the exclusive MEGA G3 spoke pattern which creates the perfect balance of spoke tensions on both sides of the wheel, reducing stress, increasing transversal rigidity and improving the transmission of power to the wheel. The hub features a carbon fibre body for a high degree of lateral stiffness with minimum weight, an aluminium axel for low weight and high stiffness and Usb ceramic ball bearings which reduce friction, provide greater smoothness and maintains performance over time. The hubs have been designed with a differentiated hub diameter front and rear, optimised for structural integrity and aerodynamic efficiency.

Zipp 303 Firecrest Carbon Tubeless Rear WheelZipp's 303 Firecrest Tubeless rim-brake rear wheel is an all-arounder for a new era of road riding. It's rich in heritage yet loaded with innovations. It's as adept in the mountains as it is on rolling hills, windswept farm lanes, or ferocious field sprints.Tubeless Ready Road Bike Rear WheelAt Zipp, they never rest on laurels. This rear wheel features a 19mm internal width and is tubeless ready. That means you can run lower tyre pressure for greater cornering grip and compliance with reduced rolling resistance without the risk of pinch flats.Lightweight Carbon with ABLC Sawtooth TechnologyWhen it comes to pure speed, the 303 Firecrest Tubeless packs a serious punch. It's lightweight with ABLC Sawtooth Technology, a complex dimpling pattern first developed for the brand's top-level NSW wheel lineup. This technology helps to achieve the optimization of low aerodynamic drag and crosswind stability, which they call AeroBalance.Rim Brake CompatibleZipp's ShowStoppertextured braking surface delivers unrivalled rim braking performance in wet or dry conditions. At the center of the 303 Firecrest Tubeless rim brake is a new versatile and durable hub, the German-engineered ZR1.Features: Rim Construction: Carbon with Hooks with UD Fibre finish and adhesive decals Rim Profile: Symmetrical Hub: ZR1 Rim Brake Wheel Size: 700c Tyre Compatibility: Tube-type or tubeless tyres Inner Rim Width: 19mm Rim Depth: 45mm Spoke Length: Drive Side: 254mm, 260mm; Spoke Length Non Drive Side: 254mm, 264mm Tyre Pressure: 125psi Freehub: Multiple options available to select Weight: 1530gKey Features: Zipp graphics and cosmetic identity that scream speed New ZR1 hub is engineered in Germany with better seal design for improved durability and quicker response with 66 points of engagement Built with Sapim CX Sprint J-bend spokes Tubeless ensuring secure performance even when ridden at lower tire pressures Versatile 45mm rim profile that's fast, stable and versatile ABLC Sawtooth dimple design helps manage air flow around the rim, and contributes to create a faster, more stable wheel Showstopper textured brake track delivers superior modulation and shortest stopping distances in wet and dry conditions XDR or SRAM/Shimano driver bodies available to select Ships with QR end caps, quick-release skewers Campagnolo driver body sold separatelyTechnologies: Showstopper: Our industry-leading Showstopper brake track continues to evolve and improve, providing unmatched stopping power and modulation regardless of weather conditions or the length of the descent. ABLC Sawtooth: ABLC Sawtooth dimple design helps manage air flow around the rim, and contributes to create a faster, more stable wheel. AeroBalance: Zipp's sole mission is to help you go faster. That's why our 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, our engineers have learned to look beyond just focusing on simply reducing aero drag. Instead, the goal now is to reduce aero drag while also minimizing 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 work together with our new HexFin ABLC dimples for improved airflow.Manufacturer's Part Number: ZPWH8532001 Black 700c SRAM XD SRAM XDR ZPWH8532000 Black 700c Shimano/SRAMBuy Zipp Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.

At only 1340 grams this is the wheel that performance-obsessed cross-country racers dream of. Developed with input from top pro racers seeking a competitive advantage at World Cups and Olympics it features an ultralight full carbon 29” rim (340g) for fast acceleration and climbing without compromising stiffness and durability.Adaptive layup a specific carbon layup technology enabled us to handcraft these carbon rims with less material between the spokes. The spoke holes are reinforced with strategically positioned carbon layering in a process that minimizes weight without compromising stiffness and strength. A lighter rim means faster acceleration more efficient climbing and a more responsive feel on the trail. The external carbon layer features our new UD² construction for a distinctive look and added durability.Extensive field testing with our pro athletes determined that a 25mm inner width was ideal for a quick precise ride quality and optimized tire grip on fast racetracks. For more technical trails some preferred a 30mm width for added control so we created two options. It’s your choice and you can mix the two if you want. You could choose the Crossmax Ultimate 25 for the rear to boost acceleration and efficiency and the Crossmax Ultimate 30 for the front to add confidence and control on rugged single-track.The carbon rim is laced with 24 straight-pull double butted spokes (same spoke length throughout) two-crossed for maximum power transfer and enhanced vertical compliance. The new lighter Infinity hub design optimizes lateral stiffness and the spoke lacing maximizes power transfer. Our Instant Drive 360 freewheel with a double ratchet system provides fast engagement and high stiffness to help you accelerate out of corners faster. The rear hub is compatible with Shimano HG9 Micro Spline and SRAM XD driver bodies.The Crossmax SL Ultimate 25 is available with 6-bolt or center lock brake rotors in 29” only and is compatible with a 15x110 front axle and 12x148 rear.
