Zipp’s first product almost three decades ago was a disc wheel. It’s at the heart of their heritage. Now, Zipp is pioneering the next generation of disc wheel, the Super-9 Disc-brake Carbon Clincher Disc. Road cycling’s latest advancement in performance – disc brakes for road bikes – is coming to triathlons and time trials, and Zipp is ensuring its fastest wheel ever is ready for this soon-to-arrive future. Braking on modern time trial and triathlon bikes often has been a challenge. The superior performance of disc brakes changes all that with greater stopping power and more precise speed modulation, all with less hand effort than required by traditional brakes. That means greater confidence in corners, descents, and on technical courses. The disc brake version of the Super-9 disc, 1175 grams for the Carbon Clincher, retains the light weight of its rim-brake counterparts. Efficient speed adjustments on technical sections of road are crucial to conserving energy and maintaining speed. Disc-brakes, standard in motorsports, gained prominence in mountain biking, then cyclocross, and now are being embraced on the road. The reason is simple: How you slow down influences how fast you go. The Super-9 Disc itself, handmade at Zipp's factory in Indianapolis, USA, optimizes supreme aerodynamics, power transfer, stiffness, lightweight and durability. Disc brakes for road also open a wider range of tire selections for improved comfort, handling and rolling resistance. The Super-9, with its aero efficiency and stiffness, quickly became a go-to disc wheel for the world’s best time trialists and triathletes and has been ridden to numerous Ironman events, world championships, Grand Tour stages, and gold medals. The new Super-9 Disc-brake Disc wheel is designed around the 177DD (for Disc) hub that features: - Improved bearing protection and sealant - Thru-axle compatible. Comes with thru-axle end caps that can be swapped by hand: 12x142mm The 177DD uses a center-locking disc-mount standard. The Super-9 Disc-brake Disc wheel comes with a standard 10/11 speed driver body for SRAM/Shimano or for Campagnolo, allowing you to run a wide range of cassettes. For those looking for a wider gear range, a SRAM XDR driver body for 177DD (sold separately) is easily installed to allow for more cassette options. A 1.85mm spacer is included with the XDR driver body and is required for use on the 177DD hub. XDR driver body compatible with 11-speed cassettes only. Each Wheel Includes: - Silca disc valve adapter - Zipp Tangente quick-release skewer - Zipp Tangente tube 700c x 20-28mm - Zipp rim tape 700c x 20mm - Zipp valve hole sticker - Zipp thru-axle end caps

Zipp’s Super-9 Disc Carbon Track Wheel underwent extensive fluid dynamic modeling, wind-tunnel testing, and relentless refinement so you can enjoy no-holds-barred aero domination. With a variance in width of just a single centimeter from rim to hub, the Super-9 is almost invisible to the wind. Plus the wide rim creates a virtually seamless integration with the tire, optimizing aerodynamics and allowing wider tires and less rolling resistance.

Light enough to fly up climbs, tough enough to excel in the cobbled classics, and with the industry’s best available braking performance for the most technical descents, the 45mm deep 303 NSW is built for a singular purpose: To be fast, everywhere. But the 303 NSW is no ‘race day only’ wheelset to be tucked away in a wheel bag until a race number is pinned to the rider’s jersey. It’s built to take the abuse of everyday training rides. Zipp has achieved this reliability at a lighter weight with a revised carbon fiber layup developed through testing on the famed cobbles of the Arenberg Forest with the world’s fastest riders. - Tubeless - COGNITION hubset - Axial Clutch technology - ABLC SawTooth - Showstopper - Faster, more stable AeroBalance rim profile - Handcrafted in the USA

When Zipp gave their top engineers in The Nest advanced development lab the task of shedding more weight from their lightest carbon clincher wheelset, the 202 Firecrest, while also improving rolling friction, aerodynamics, and braking, it was a very tall order. When they asked them to do all of this without sacrificing durability, it looked like an impossibility. But the NSW advanced development team delivered on every request and built the ultimate climbing wheelset, a climbing wheelset strong enough to use on every ride. Engineered to be the fastest accelerating carbon clincher Zipp has ever made, 202 NSW flies up the toughest climbs, and then shaves even more time off of the descents to follow. And because extracting greater speed on the mountain is only half the battle, they built the 202 NSW to deliver the lowest aerodynamic drag available for a rim of this depth for speed everywhere else. In order for a climbing wheelset to be world beating it has to do more than simply deliver low weight; it has to deliver uncompromising performance on every level. This is why Zipp engineers in The Nest chose to enhance the world’s fastest climbing carbon clincher, the 202 Firecrest. With a new lighter carbon fiber layup for the 32mm deep 202 NSW, they’ve dropped weight where it matters most, at the outer edge of the wheel, while maintaining the durability and lateral stiffness that Firecrest is famous for. Then they reduced aerodynamic drag with ABLC Sawtooth technology and used ImPress graphics to ensure that nothing stood between the air flowing over the rim and the dimples made to smooth that flow. Knowing that there is no benefit to a wheelset that climbs fast and descends slow, NSW engineers incorporated their Showstopper brake track for the most confidence inspiring rim braking performance available, whether the road is wet or dry. To further improve the wheelset’s rolling efficiency, the 202 NSW rim is laced to their groundbreaking Cognition hubset. Built around their Axial Clutch freehub technology, the Cognition rear hub is engineered to maintain speed when coasting by disengaging the ratchet mechanism. This technology enables the Cognition rear hub to deliver far less rolling friction than wheels using conventional freehubs—a real advantage when fighting through rolling foothills or when spun out on long descents. Engineered for speed when approaching, ascending, traversing, and descending the world’s toughest mountain roads, the Zipp 202 NSW is a wheelset that can only come from one place, The Nest, where the world’s fastest wheels are made.

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 fiber and a honeycomb-foam filling, or a spoked wheel that's been faired with a carbon fiber cover. In our quest to break traditions, the 321 uses a single layer of 1k carbon fiber on each side of the wheel, and it all comes together at the brake track bridge. This kind of carbon fiber 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 fiber craftsmen. It's complicated, but the payout 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. - Rim Type: Full carbon clincher, 2Bliss Ready - Rim Material: Carbon - Braking Surface: Disc brake only - Rim Depth: Solid Disc - Rim Width: 19mm internal, 27.3mm external (at brake track) - Rear Hub: Roval Disc 142x12mm, CeramicSpeed bearings, DT Swiss 240 internals, 11-speed - Assembly Method: Handmade - Extras: Roval padded wheel bag, Roval tubeless valve, Roval valve pocket covers - Weight: 1015g
