No need to fret—we haven’t forgotten about all you alloy fans out there. In fact, the new Stumpjumper Comp Alloy 29 with 12-speed SRAM NX Eagle may be the most radically designed alloy bike ever made. For real, though. And with new tube shapes and an asymmetrical design, it's going to exceed all of your expectations of how a trail bike should ride. Our design goal for the new Stumpjumper was simple—build the ultimate trail bike, one that feels telepathic. And it turns out that this feeling all comes down to stiffness. Think of it this way: when the frame's telling your hands one thing and your feet another, your brain gets confused with the imbalance and the bike feels unstable. In order to fix this, we had to get to work on dialing-in the material and shapes. We continued down the suspension path with a custom Rx Trail Tune on both the fork and rear shock. Suspension performance is highly dependent on frame, wheel, and rider size, so we use our Rx Tune to get each bike to land in the middle of the adjustment spectrum, and this gives you the biggest possible range to fine-tune your ride. Another focal point of the tune was matching the suspension characteristics between wheel sizes—we developed a specific Rx Tune for each platform. So, no matter what wheel size you prefer, you’ll get perfectly linear suspension. Steps were also taken to make this bike easy to live with. Threaded bottom brackets make a triumphant return, and we made room for up to a 3.0'' tire. You're also free to run whatever aftermarket rear shock you want because we're using standard metric shocks. And customization is furthered with a Flip Chip that lets you to dial-in your Stumpy to your riding style. Switch it from High to Low and it drops your bottom bracket 6mm and slackens the head tube by half-a-degree. Little details also jump out to surprise you, like a newly designed ribbed chainstay protector that makes chain slap a thing of the past and nearly silences the drivetrain. The build on this Comp model comes with a list of components that deliver undeniable quality, like a 12-speed SRAM NX Eagle drivetrain, SRAM Guide R disc brakes, FOX front and rear suspension, and Roval Traverse 29 wheels. - The completely redesigned alloy Stumpjumper frame features an M5 alloy front- and rear-end, an asymmetrical design, and our 29 Trail Geometry, so it's just the right amount of both capable and comfortable. - The FOX DPS Performance rear shock features our Rx Trail Tune, ensuring that no matter the wheel or frame size, your bike is dialed-in perfectly. - SRAM's 12-speed NX Eagle groupset features a wide gear range that delivers climbing and descending efficiency in spades.

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.

At the pinnacle of Zipp's wheel lineup confidently sits the 808 NSW Carbon Clincher. With a host of technological advancements that all contribute to making the 808 NSW an elite-level triathlon and time trial rim, this may be the missing piece from your podium finish puzzle. With increased gains upon Zipp's standard 808 Firecrest rim, the NSW provides proven energy savings thanks to a new rim dimple design, called SawTooth, that decreases the laminar bubble effect that contributes to drag and crosswind instability. Also, graphics are printed directly on the wheel instead of using stickers that decrease hard-earned aerodynamic development. At the heart of Zipp's 808 NSW is their new Cognition hubset, which reduces freehub drag by disengaging the rear ratchet mechanism when coasting. The front hub features a scalloped-edge design that maintains truer hub bore diameter in high-tension spoke applications for lateral stiffness and faster-rolling bearings with increased service life, giving you the advantage when every second counts. Wrapping the efficient rim design is a silicone carbide "Showstopper" brake track that provides worry-free stopping power and modulation regardless of weather conditions or length of descent, thanks to molded-in texture with silicon carbide particles suspended in the surface resin. Each Zipp 808 NSW wheel comes with a titanium skewer, Silca valve extender, wheel bag, Zipp Platinum Pro Evo brake pads, Zipp tube (700c x 19-25mm), and Zipp rim tape (700c x 20mm).

Built on the foundation laid by Firecrest, offering unrivaled crosswind stability and the most aerodynamically efficient rim design on the market, the 303 NSW takes it all to the next level. Like its siblings, 404 NSW and 808 NSW, Zipp's top engineers in The Nest advanced development lab incorporated improved aerodynamics, industry leading braking performance, and reduced rolling friction to produce the lightest, highest-performance 303 wheelset Zipp has ever made. 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 Forest of Arenberg with the world's fastest riders. Because the toughest roads often experience the toughest weather conditions, they've included Zipp's Showstopper brake track for braking performance that delivers the best modulation and shortest stopping distances in wet and dry conditions. And they've improved aerodynamics with their ABLC Sawtooth technology and Impress graphics to produce a rim that is as fast as it is stealthy. At the center of the 303 NSW wheelset is the Cognition hubset. Built to provide the lowest rolling friction possible without compromising sealing, the hub's Swiss-made bearings work in tandem with Zipp's Axial Clutch technology to dramatically cut rolling friction when compared with conventional freehub systems. Bottom line: Cognition hubs make the 303 NSW fast, even when you aren't pedaling. All of these technologies combine to build a wheelset that only NSW technology can produce, a wheelset with unrivaled performance. Wherever the road may take you, get there faster on Zipp 303 NSW wheels.

Following the success of the 808 NSW, which was ridden to victory at the Pro Men’s Ironman World Championships and the Elite Women’s UCI Team Time Trial World Championships, Zipp is proud to launch their second wheelset in the NSW Series, the Zipp 404 NSW Carbon Clincher. Zipp's advanced development engineers in their top-secret lab, known as The Nest, have delivered a wheelset with improved braking performance, exceptional aerodynamic efficiency, and unparalleled crosswind stability with the most popular and best-selling rim depth. Like the 808 NSW, the 404 NSW also makes use of a Cognition hubset for increased durability and exceptionally low freehub drag. No matter where you ride, the 404 NSW is engineered to make that ride faster. With a rim depth of 58mm, the 404 NSW is designed as a do-everything wheelset that is adept at climbing and maintaining speed on the flats; a wheel strong enough to handle the Spring Classics, but light enough to inspire sprints out of corners. With its advanced aerodynamics, developed using 42 different CFD (Computational Fluid Dynamics) concept studies and months in the wind tunnel, the 404 NSW’s unrivaled crosswind stability saves watts that would have been spent keeping the bike straight, and provides unequivocal confidence for high speed descending. When it comes time to slow for a corner, the NSW-exclusive Showstopper brake track stands ready to deliver the best modulation and shortest stopping distances available, regardless of weather conditions or the length of the descent. Simply put, the 404 NSW represents the cutting-edge of carbon clincher wheel technology delivered straight from The Nest, where Zipp’s advanced development engineers design the world’s fastest wheels.
