Making up about 50% of your total race time the bike portion of a triathlon is where equipment choices can make the difference between first and fifth and no other equipment choice will save you more time than a disc wheel. While traditionally-shaped disc wheels are faster than their spoked counterparts the Roval 321 Disc for disc brakes turns conventional design on its head creating the fastest wheel on the planet. Disc wheels often fall into two categories—a completely flat shape with structure coming from carbon fibre and a honeycomb-foam filling or a spoked wheel that's been faired with a carbon fibre cover. In our quest to break traditions the 321 uses a single layer of 1k carbon fibre on each side of the wheel and it all comes together at the brake track bridge. This kind of carbon fibre is rarely used in bicycle components due to its high manufacturing cost but it offers a bevy of performance benefits. This coveted carbon is much lighter than other layups like 3k and 12k and it can only be laid by the most skilled of carbon fibre craftsmen. It's complicated but the pay-out is worth it as it delivers a supple ride and one of the lightest disc wheels available. And in the real world this means that it'll spin-up quickly and reduce fatigue over the length of the course. Stiffness is often the “hot-topic” in the disc wheel world but we think it’s an interesting conversation. It's long been thought that efficient power transfer and high stiffness are directly correlated but through extensive field-testing we've determined that this isn't the case at all. In fact our initial disc was so stiff that under power it wouldn't flex with the frame and this caused brake rub. This wrongly creates the perception of a flexy wheel when really the wheel is actually too stiff. In order to solve the brake rub problem we first designed our optimal aero shape and then worked on our internal stiffness targets to fit within what we consider to be a desirable frame stiffness. And while light overall weight was a development priority our focus was aerodynamics. Through hours of Computational Fluid Dynamics (CFD) and testing in the Win Tunnel we developed a never-before-seen shape that's optimized to work with a tire for on-bike airflow. What this translates to is an all-carbon disc wheel that on the non-drive-side has a shape that's as aerodynamic as our current understanding allows and a drive-side shape that's as aerodynamic as the wheel-dish and derailleur clearance will allow for. To save every possible watt we've also added CeramicSpeed bearings and DT Swiss 240 hub internals into our hub. Each 321 Disc wheel is also 2Bliss Ready right out of the box and comes with a padded wheel bag quick-release and tubeless valve stem. Designed for the most uncompromising athletes in the world with engineering to match the 321 Disc is the world's most advanced disc wheel for your race against the clock.

Zipp’s 454 NSW 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 tires 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 tires for all out speed. The 454 NSW features Zipp’s most advanced technologies. Its undulating 58mm Sawtooth rim shape with Hyperfoils is our 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 tire 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 tires required 278 watts to maintain a speed of 40kph. That’s a 10-watt savings compared with the previous model 454 NSW.

Managing this is crucial to stability. Sawtooth: SawTooth is the name given to Zipp NSW's patented variable depth 53/58mm rims. Developed utilising the principles of the emerging science of biomimicry, Zipp engineers began the rigorous aero development process of SawTooth utilising the wind tunnel, CFD, and real-world testing. The result is a rim shape that takes nature's most elegant design solutions and combines engineering precision to deliver a wheel that performs unlike any made before. This patented rim shape achieves something conventional aero wheels cannot; it simultaneously reduces both aerodynamic drag and side force for the ultimate in AeroBalance. Sawtooth accomplishes this with a series of patented fin-shaped Hyperfoil nodes along the inner diameter of the rim that work together with HexFin ABLC dimples for improved airflow. The result is Zipp's highest performing wheel ever released with both aero-drag reduction and reduced side force at all wind yaw angles. This is important because higher wind yaw angles are where bike handling is most affected by the wind. Hyperfoil: Hyperfoil is the name given to the individual nodes on Zipp NSW variable depth Sawtooth rims. Each of these patented structures features Zipp's HexFin ABLC dimples that help to stabilize handling in gusting wind by increasing wind vortex shedding frequency. The higher frequency vortex shedding produced by Sawtooth creates a greater number of smaller, less powerful, yet more predictable vortices leading to greater wheel stability. This added stability translates into greater rider control, thereby saving energy that is typically expended trying to hold a line in gusting wind. The result is a faster, more confident riding experience whether you are laying down power or descending sinuous mountain roads.Hexfin ABLC: HexFin ABLC dimples are the hexagonally shaped depressions found at each Hyperfoil of our Sawtooth shaped NSW rims. The angular shape of each dimple increases boundary layer mixing to help keep airflow attached to the rim for reduced aerodynamic drag and improved stability in crosswinds. To further improve the effectiveness of the hexagonal dimples, they are arranged in fin-shaped clusters made up of variable sized dimples that work in concert with each Hyperfoil of a Sawtooth rim.Axial Clutch: With Cognition's Axial Clutch technology, Zipp reduced drag by disengaging the ratchet mechanism when coasting. With less internal hub drag a rider can pedal less when drafting in a headwind, achieve higher speeds when coasting in an aero tuck, or opt to stop pedalling a moment sooner before entering a corner and bank that wattage for use exiting the corner. Axial Clutch technology also allows riders to maintain speed through corners that don't require braking input, thereby increasing corner exit speeds. Inside the Axial Clutch mechanism Zipp use magnets, rather than steel springs, to move and engage the lightweight Metal Injection Molded (MIM) ratchet rings for unmatched reliability and consistent operation. With 36 points of engagement that all interlock simultaneously, there isn't a more secure freehub mechanism on the market. TSE Technology: Zipp's TSE Technology (Total System Efficiency) was developed by its engineers in the Nest Advanced Development Lab in Indy. This approach to carbon-wheel manufacturing means the wheel's precise rim layup results in greater all-around efficiency for greater speed through reduced: Wind resistance, rolling resistance and gravity (weight + durability) vibration losses.Manufacturer's Part Numbers: Shimano HG 10/11 speed: ZPWH8613000 SRAM XD 10/11/12 speed: ZPWH8613001Buy Zipp Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.
