Feel your bike come alive on the open road with the new Alpinist CLX II—the lightest, best-handling clincher wheels we have ever made. Hyper-responsive acceleration, magic in the corners, sublime over rough roads, all elevated with the performance of a tubeless system. There’s no room for a single excess gram whether you’re chasing summits or ride quality because perfection is only achieved when there is nothing left to take away.It takes more than a lightweight rim to deliver the incredible reactivity and handling of the tubeless Alpinist CLX II. The wheelset is designed as a system with our engineers controlling and testing every part of that system—hubs, rims, spokes, lacing—and developing it hand-in-hand with Specialized Tubeless tires. The result is a 1250-gram tubeless wheelset with otherworldly ride quality.The Alpinist CLX II utilizes a hooked rim (allowing for real-world riding pressures up to 110psi, if that’s your thing) for secure tire bead retention and an easier set up and mounting experience than ever before. All in a wheel that almost doubles current industry impact standards while managing to achieve the lightest weight possible.Our all-new LightAF hubs are the spinning heart of the Alpinist CLX II. We carved 50 grams out of the previous Alpinist CLX hub with new low-profile hub bodies and machined rotor mounts. Inside, DT Swiss EXP internals and SINC ceramic bearings deliver silky-smooth efficiency and outstanding durability.Rim: Alpinist CLX Cabon Clincher, 700c, Disc Brake, Tubeless,Rim Details: 33mm Depth, 27mm External Width, 21mm Internal Width,Hub: Roval Light Hub (LFD13/LF14R) Center Lock, DT Swiss 180 Ratchet EXP 36t internals (10 degs), 100x12mm & 142x12mm, Shim.

Zipp’s 808 Firecrest® Tubeless Disc-wheelset is pure engineering science. It has to be. To achieve speed with an 82mm rim depth is one thing but to be fast while offering high crosswind stability well that requires serious attention to detail. Yet that’s just what the 808 Firecrest Disc brake accomplishes – speed with stability and tubeless compatibility. That means you get all the aero benefits with having the ability to run lower tire pressure for increased cornering grip and compliance and reduced rolling resistance without the risk of pinch flats. You also get the greater stopping power of disc brakes. This wheelset is infused with technologies developed in Zipp’s Indianapolis advanced development lab. Zipp’s ABLC™ Sawtooth™ Technology uses a complex dimpling pattern to improve aero efficiency. At the center of the 808 Firecrest Tubeless Disc-brake is a versatile and durable new hubset the German-engineered ZR1 DB. Zipp’s new wheel cosmetics make this wheelset a perfect pairing of speed and style. FEATURES Zipp graphics and cosmetic identity that scream speed ZR1 DB 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 An all-out aero 82mm rim profile that’s tubeless ready for increased speed and better cornering control and comfort ABLC Sawtooth™ dimple design helps manage air flow around the rim and contributes to create a faster more stable wheel Center locking rotor interface.

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.

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.
