You want the best of the best, no compromises, aerodynamic, light and fast. The RAW is the wheel set for you! Striving to produce the best wheels on the market, we completely designed the RAW rim from scratch and combined it with the highest quality components to achieve the optimum result. In an evolving world of wider tires for multi-surface racing and riding wheel aerodynamics have adapted. With this concept the RAW and RYOT44 feature a newly developed LAW Tech aerodynamic profile. LAW is short for ‘Laminar Airflow Wing’ and has been specifically developed to deliver better aerodynamics when using wider tire widths up to 42mm by creating a smooth airflow over the rim and tire interface. The RAW is a 700c tubeless ready carbon clincher rim with a 21mm internal width, 44mm depth and 30mm external width. Testing multiple layups and setups have led to the optimum combination of stiffness, aerodynamics and weight.
Zipp s 454 NSW Carbon Tubeless Disc Brake is the ultimate road racing wheelset. This wheel delivers everything the performance cyclist demands. It s aerodynamically efficient and stable in all wind conditions. What s more, a wider rim is designed for tubeless tyres at lower pressure for reduced rolling resistance and vibration damping, so you ll lose as little energy as possible out on the road. This wheel is optimized for 25mm tubeless tyres for all out speed.Technology: Total System Efficiency, ImPress, Sawtooth & Axial Clutch V2Cognition hub set rolls efficiently whether you are pedalling or coasting with Axial Clutch V2 technology The 454 NSW Tubeless Disc Brake is roughly a pound (more than 400 grams) lighter than its predecessorTSE for greater efficiency and reduced rolling resistanceSawtooth rim with Hyperfoil nodes and Hex Fin ABLC dimple pattern for top aero and cross wind stability performance with an undulating 53/58mm rim depth Zipp graphics applied using Zipp s ImPress direct-print technologyXDR SRAM/Shimano driver bodies Ships with 12mm front and rear end capsCentre locking rotor interface.Lockring is included with the wheels Campagnolo driver body sold separatelyFront 631g / Rear 727gLifetime WarrantyThe 454 NSW features Zipp s most advanced technologies. Its undulating 58mm Sawtooth rim shape with Hyperfoils is Zipp s most aerodynamic and stable wheel in the 404 family. 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.

Famous for their craftmanship on road and track wheels, Campagnolo have applied their expertise to the gravel market. The Levante wheelset is reactive, versatile and durable they are made for Point and Shoot handling. Stiff for climbing, light for handling and compliant for descending, Levante benefits from Campagnolo’s Handmade Ultra-Light Carbon (H.U.L.C) which is used in the rim construction and is the result of extensive development over decades of in-house carbon fibre moulding. This enables Campagnolo’s engineers to optimise the usage of both fibre and bonding resin for the perfect blend of strength, stiffness and light weight. All of this combines to create an awe-inspiring ride feel without undue harshness and a wheelset that weighs in at just 1485g. The Levante rim sports the beautiful mirror-like finish aptly named Campagnolo Luxury (C-LUX). This finish is so pristinely smooth that it doesn’t require any additional lacquer, saving valuable grams across the wheelset. The Levante pairs this stunning finish with durable laser-etched rim graphics capable of withstanding even the most demanding of gravel rides. Campagnolo’s consideration for durability is deeply rooted in the Levante Wheelset, and the premium H.U.L.C construction combined with an asymmetric offset on the rim provides a strong and balanced wheel that can take the rough with the smooth. A simple cup and cone hub system meanwhile ensures ease of servicing and external nipples allow for tool-free on-the-go spoke tensioning if needed. Not only is the Levante wheelset durable but it’s versatile too. Campagnolo’s two-way fit rim profile ensures tubeless and clincher compatibility while the 25mm internal rim width can accommodate 38mm to 78mm tyres (1.5-3.0”). The wheelset’s Mini-Hook has been designed specifically for the Levante rim and matches the E.T.R.T.O Clincher and Tubeless requirements using the most minimal dimension possible. As a result, the slight hook provides a perfect match between the tyre and rim. This means a large contact area with the terrain, increasing grip and comfort at lower pressures. Campagnolo’s Next 3 Ways (N3W) is compatible with Campagnolo 11, 12 and 13-speed cassettes. The wheelset is also available with freehub bodies for Shimano HG and SRAM XDR.

First launched in 2011, Zipp’s 404 Firecrest wheelsets are not only firmly established as one of the fastest wheels on the market, but also they have arguably helped shape the entire category of modern aerodynamic wheels. This iteration, to use the company’s term, is no less than a ‘Speed Weapon’; a ‘weapon’ that boasts a 58mm-deep rim and weighs less than ever at 1470g. It is now cheaper than before, making this a product that’s virtually a no brainer. Whether you’re looking for a wheelset fit for a Spring Classic, time trial, triathlon, or simply to compete against your mates on the weekend club run, this is an option which is hard to look past. Single Purpose: Speed Whereas the 303 Firecrest is Zipp’s premium all-rounder, which’ll happily serve its rider on or off road, the 404 is all about going fast. Somewhat unusually, the company aren’t claiming to have made a more aerodynamic rim, quite the opposite. As the rim is wider, the shape is actually less aerodynamic than the previous version. However, a multitude of other enhancements — what has been termed Total System Efficiency (TSE) — has enabled the developers to produce a faster-overall wheelset. In addition to examining how wind resistance affects the wheels, the effect of gravity, rolling resistance, and vibration losses have also been tested. Notably, the internal width of the rim is now wider at 23mm, and has been optimised for a tyre of 25–28mm — depending on rider size. This allows the tyre to be ran at a lower pressure and in turn means it can roll more smoothly over imperfect road surfaces, increasing efficiency and making for a faster wheel overall. The weight of the wheelset has also been reduced, increasing its speed and lessening the impact of gravity when going up-hill. All this adds up to a wheel that is faster on varied terrain and ever-changing riding conditions. Going Hookless Hookless rims are slowly becoming the de-facto choice for wheel makers, at least in the high-end wheel space. What this means is, instead of the traditional ‘hook’ on the inside of the rim, the wall is straight. This comes with a number of manufacturer-claimed benefits. For one, with a hookless rim, the transition between the tyre and rim is less abrupt, which helps to cut a cleaner shape through the air. As well as the performance benefits, hookless rims are also cheaper, easier, and more environmentally friendly to produce, all of which amounts to cost savings for the buyer. The Hub Spinning the wheelset is an all-new, German-engineered, versatile and durable hubset. Using a six-pawl freehub, with 66-point engagement, the hub has a pick-up angle of 5.45 degrees so that when you put the power down, it’s translated to forward motion almost instantly. Overall, if you are looking for just one wheelset for road riding, be that for racing or simply for fun, then the 404 Firecrest is a difficult option to look past.
