Wheels

Don't worry, S-Works doesn't get to have all of the fun—the new Stumpjumper Comp Carbon 27.5 features the same frame with a full 11m carbon chassis and rear-end as its older brother, but with a solid list of no-fuss components, including a SRAM NX Eagle 12-speed groupset, for an everyman's budget. 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 materials, shapes, and the layout. We started by creating our own mountain-specific stiffness test, and then we looked at the layout with Finite Element Analysis (FEA) to see where we could get the biggest stiffness improvements. This led to a big discovery: The Large and X-Large frames needed more front-end stiffness while the Smalls and Mediums were just fine. We were able to create a frame design that was 20% more efficient. And in the end, this proved to be one of the lightest trail frames on the market today. When designing the frame with the stiffness targets being a main goal, we developed a radical new sidearm design. The front-end and rear-end are connected at three points, and the sidearm helps keep all these points super stiff and connected, all while taking about 100 grams out of the rear-end. More explicitly, this minimizes frame flex when the rear suspension is active. 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 since we're using standard metric shocks. We revamped the SWAT box, too, making it sleeker, lighter, and with more volume. 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. Lastly, we seriously couldn't make cable routing any easier on carbon models. Full tubes can be found throughout the carbon frame, so all you have to do is push the cable and it'll come out the other end. No more lazy loop, hidden stashes of magnets, pokey spokes, or pillows to cry in. 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 27.5 wheels. - The Stumpjumper's asymmetrical, FACT 11m carbon fiber construction is lightweight, stiff, and ready to take on the trail. It's built off our 27.5 Trail Geometry, so it's just the right amount of both capable and comfortable. And with SWAT integration in the down tube, a threaded BB, easy cable routing, and an all-new chain silencer, it's ready for anything the trail, or you, throw at it. - 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.

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.

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

While the CLX 32 rim is the lightest and most aero in its category, there's much more to it than that. It’s a durable, 2Bliss Ready, and wide-profiled carbon rim that’s ready to take on any adventure. Because of this, we developed the CLX 32 650b Disc wheelset. We wanted to create a lightweight wheel that works well with plus-sized tires—one that could also be used on anything from tarmac to gravel. And yes, while many opt to use mountain bike wheels for this application, there are various advantages to choosing the CLX 32 650b Disc. First off, while most mountain wheels have hubs that are convertible to various axle standards, not many are convertible to the 12mm road thru-axle standard. Secondly, mountain wheels often come with either a SRAM XD driver, a Shimano 11-speed mountain, or 10-speed road freehub, making them incompatible with contemporary 11-speed road cassettes. And lastly, most mountain wheels use standard six-bolt disc brake hubs, rather than the Center Lock hubs found on most road applications. With a 21mm internal width, however, the CLX 32 650b Disc features an inner width that’s consistent with many XC-oriented mountain bike wheels, so it pairs well with 650+ road and gravel tires. And with the 42-47mm tires associated with 650+, the tire and rim interaction is equally as important as the tire itself—too narrow of a rim and you’re left with an overly-rounded profile; too wide and the tread is too squared off. In either situation, you're going to get poor handling characteristics. Each CLX 32 650b Disc set also uses the legendary CeramicSpeed bearings and comes with our padded wheelbag, quick-release, tubeless plugs, and tubeless valves. - Rim Type: Carbon clincher, 2Bliss-Ready - Rim Material: Carbon - Braking Surface: Disc brake only - Rim Depth: 32mm - Rim Width: 20.7mm internal - Spoke Pattern: One-cross/Two-cross (2:1) - Spoke Count: 24 - Spoke Type: DT Swiss Aerocomp (L)/Aerolite (R) T-head - Nipple Type: DT Swiss Pro Lock hexagonal - Rear Hub: Roval AFD2, Centerlock, CeramicSpeed bearings, DT Swiss 240 internals, 11-speed, quick-release or 142x12mm thru-axle end cap - Assembly Method: Hand-built - Extras: Roval padded wheelbag, Roval steel quick-release, Roval tubeless plugs and tubeless valve,142x12mm thru-axle & quick-release end caps - Wheelset weight: 1290g

The CLX 64 Track Tubular was brought to life under the Allez Allez team at the 2016 Red Hook Crit. Along these lines, you get all of the unrivaled aero performance of the CLX 64, albeit with DT Swiss track hubs and Aerolite spokes, for a stiff, smooth, and most importantly, fast ride on the boards. One of the first questions we get about the CLX 64 is, “Why 64mm instead of 65mm?” To put it simply, it's because 64mm tested faster than 65mm. One millimeter—that's how deep our testing goes. Having an in-house wind tunnel allows us to run every possible variation, and after two-years of development, 80 variations in rim design, and nearly 300 hours of Win Tunnel testing time studying tire and frame interactions, we found 64mm to be the fastest iteration for normal riding conditions. In fact, it's even faster than the 80-plus-millimeter-deep wheels they were tested against. Being able to use a shape that’s nearly 20mm shallower than the competition, yet just as low in drag, makes for a wheel that has drastically less side force and steering torque. This translates to less buffeting and more confidence in even the gustiest winds. Another positive of a shallower rim depth is the reduction in weight that follows using less material. Many deep carbon wheels feel “slow” due to their high inertia value. What's that? Inertia is the amount of force it takes to accelerate or decelerate, and wheels that are built around heavier rims lack the liveliness that many riders crave. Being over a half-a-pound lighter than the other wheels in its aero category, the CLX 64 accelerates, decelerates, and changes direction with less effort.

What you're looking at here is gravity's nemesis: Roval's Control SL 29 Wheelset 148. At 1,330 grams, you'll climb XC courses with ease on these lightweight, hookless-bead, carbon hoops. They're built to withstand grunting up climbs, descending with abandon, and blasting in and out of corners with Specialized carbon rims, DT Swiss spokes, and DT Swiss's legendary 240 rear hub internals. The Boost spacing offers increased width on the front and rear hub flanges, and in turn, increased frame and fork clearance and stiffness. This combines to deliver a more durable wheel system at a minor weight penalty. Plus, these sweet race-ready wheels are tubeless-compatible so you are ready for anything that the trail throws at you.

The Roval Control SL 29 Torque Tube 148 wheels are nearly identical to the Control SL 29s, with the only exception being at the front hub. With the Torque Tube 148mm variant, you receive all of the benefits that Boost spacing offers while continuing to run a RockShox RS-1 fork. By increasing the width of the rear hub flange, and in turn, increasing frame clearance and stiffness, you obtain a stiffer, stronger, and more durable system at a minor weight penalty. If you're running an RS-1, you'll get hand-built, ultralight carbon perfection with a Zero Bead Hook design. This design pairs perfectly with tubeless tires, while also increasing both strength and impact-resistance. Meanwhile, the rims have been laced via DT Swiss Competition Race spokes to strong alloy hubs with DT Swiss 240 internals (rear only) that serve-up lightening-fast engagement and acceleration.

While there may be a linear relationship between increased tire size and increased fun, this relationship only holds true when wider tires are paired with the correct width rims. Having a 2.8", or high-volume, tire mated to a narrow rim makes for a squirmy, poor handling experience, and when you’re on the hunt for additional fun, these characteristics are undesirable. Lucky for you, the new age of traction, stability, and speed has arrived—and its name is the Traverse 38 SL Fattie 27.5. Along with light overall weight, stiffness, and durability, another top priority for the Traverse SL was ease of use. First off, we got rid of the creaky straight-pull spokes and corrosion-prone alloy nipples. Next up, we landed on 28 J-bend spokes, for front and rear wheels, that are all the same length—making it easy to find replacements if needed. And finally, we engineered a new hub design, with a wider profile and higher flange to aid in overall stiffness. While our 38-millimeter Traverse SL is already wider than most offerings, the benefits of three-inch tires become more apparent with a proper rim interface. In search for the proper width, our engineers tested various iterations, from 30 to 45 millimeters, to determine where the sweet spot lies. What they ended up with is a 38-millimeter internal rim width that turns the Traverse 38 SL Fatties into descending machines. A wide internal rim width endows riders with a variety of advantages that are exemplified even more with plus-sized tires. The extra width allows for more tire volume, translating into more supple ride qualities, and better support for the tire, meaning that you'll experience less "burping" when riding tubeless and a drastic increase in traction. After determining the proper rim width for the plus-sized application, we began designing the rim using the same low-weight, high-strength technologies used in the Traverse SL and the Control SL. With this, we started with our Zero Bead Hook design that effectively eliminates the biggest weak spot found in traditional rims, and topped it off by using high-modulus carbon fiber to keep the weight down. And to further this theme, the wheels also include the Roval tubeless plug system, which sheds an additional 50 grams-per-wheel compared to a rim strip Each Traverse 38 SL Fattie is hand-built to our own alloy hubs with DT Swiss Competition Race spokes. Inside our hubs, you'll find sealed cartridge bearings all-around, and a quick-engaging 54t DT Swiss star ratchet system in the rear that allows you to power over rocks and roots without delay. And while machines do a decent job of building wheels, we choose professionally trained humans to build ours, as they catch various flaws that a machine would otherwise miss.

Trail wheels often fall into two categories—they’re either heavy and durable or light and flexy. And because of this, a lightweight, wide-profile, and enduro-ready carbon wheel seems like something only found in a fairytale, but lucky for you, we made it a reality. The Traverse SL Fattie 27.5 puts all the flick'able, nimble features you need in an all-mountain wheel into one package, and it has the results to prove it. Along with light overall weight, stiffness, and durability, another top priority for the Traverse SL was ease of use. First off, we got rid of the creaky straight-pull spokes and corrosion-prone alloy nipples. Next up, we landed on 28 J-bend spokes, for both the front and rear wheels, that are all the same length—making it easy to find replacements if needed. And finally, we engineered a new hub design, with a wider profile and higher flange to aid in overall stiffness. What's with the big-boned name, you ask? The Traverse SL Fatties may be wide, but with a 30mm inner rim width, they’re far from the girth of a fat bike rim. But let's talk width. You've probably noticed that mountain bike rim widths have hovered between 19 and 23 millimeters for decades, and they've been long overdue for a change. In the search for a better wheel design, our engineers began testing 2.3- to 2.5-inch tires on 45-millimeter-wide fat bike rims to see what, if any, benefits could be found. It only took them a few rides to realize that the wider rims offered a variety of advantages, like adding additional tire volume, which better supports the tires in hard cornering, greatly improves traction because of the ability to run lower pressures, and noticeably increases rim stiffness. They did note that there is an occurrence of diminishing returns with increasing width, however, and after testing everything from 25 to 45mm, determined that a 30mm inner width is optimal. After determining the width, we began designing the rim using the knowledge that we gained when developing the Control SL. With this, we started with our Zero Bead Hook technology that gets rid of the weak spot found in a traditional wheel, and combined it with the wider profile to make a carbon rim that effectively dissipates forces. This way, you can take abuse from rocks without the worry of cracks or dents. Ok, so they’re strong, impact-resistant, and tire supporting—they must be heavy, right? Wrong. Even though “fattie” is in their name, they're far from fat. To achieve this weight, we hand-build our rims to our own alloy hubs, using only the highest quality DT Swiss Competition Race spokes. Inside our hubs, you'll find DT Swiss 240 internals with a quick engaging 54t DT Swiss star ratchet system in the rear that allows you to power over rocks and roots without delay. And while machines do a pretty good job of building wheels, we choose professionally trained humans because they do so with an artistic touch that makes for minimal flaws. Whether you need a carbon wheelset to get you through an enduro stage or one to shred your local rock garden, the Traverse SL Fattie has you covered.

Gravity's grasp just got a little weaker. With Roval's Control SL 29 Torque Tube Wheelset coming in at an impressive 1,440 grams, you'll climb with ease. The lightweight, 30mm-wide carbon rims respond almost telepathically to accelerations, changes in direction, and the ins and outs of the trail. To add durability to the mix, DT Swiss's legendary 240 rear hub internals, SRAM's super-stiff Torque Tube front hub, and DT Swiss spokes make these wheels as ready for epic miles as they are light. And for versatility, the rear hub is compatible with a standard 135mm quick-release or a 142mm thru-axle. Please note: The front wheel only fits RockShox's RS-1 fork and the wheelset has a rider weight limit of 240 pounds.

The Roval Control SL 29 Torque Tube wheels are nearly identical to the "standard" Control SL 29s, with the only exception being at the front hub. For this wheelset, the front hub features a SRAM Torque Tube design that's intended for use exclusively with the RockShox RS-1 fork. Again, it's not compatible with any other fork. However, if you're running an RS-1, you'll get hand-built, ultralight carbon perfection with a Zero Bead Hook design. This design pairs perfectly with tubeless tires, while also increasing both strength and impact-resistance. Meanwhile, the rims have been laced via DT Swiss Competition spokes to strong alloy hubs with DT Swiss 240 internals (rear only) that serve-up lightening-fast engagement and acceleration.

After designing the CLX 50s, we realized that an affordable, race-worthy carbon wheelset was nowhere to be found—until the CL 50 Disc was developed, that is. We paired our quiver-killing CLX 50 Disc rim with DT Swiss Competition round spokes, our Aero Flange Disc hubs with DT Swiss 350 internals, and steel bearings to deliver you an exceptional wheelset at a more than accessible price. Why disc you ask? With our disc-specific rims, you not only ditch the brake track, but you get a stronger, more impact-resistant rim. This comes at the hands of a disc-specific carbon layup that optimizes stiffness and keeps weight as close to its rim-brake brethren as possible. And all the while, you get incredible brake modulation and power in all conditions. Sharing rims with the CLX 50s, the CL 50s feature many of the benefits as their higher-end siblings. Even though the CL 50 is similar in weight to many wheels in the “lightweight” category, aerodynamics came at the forefront of the development. With this, we jumped headlong into Computational Fluid Dynamics computer modeling to arrive at various rim shapes that could make the CL 50 as fast and light as possible. It took a while, but we narrowed the rim shape down to three contenders that were then CNC machined into rims, built into wheels, and put into the Win Tunnel. In the tunnel, we tested every wheel, ours and the competition's, with a 24C tire (measuring 26C), as tires can drastically affect testing. We chose a modern-width tire to design our rims around, because they not only allow for less tire pressure (which results in more comfort and less rolling resistance) but are also just as aerodynamically efficient when paired with the correct rim width. Now it was time for final testing validation. The result? A 50mm-deep, 1515-gram clincher wheelset that's race-ready and wallet-friendly. - Rim Type: Carbon clincher, 2Bliss-Ready - Rim Material: Carbon - Braking Surface: Disc brake only - Rim Depth: 50mm - Rim Width: 20.7mm internal, 29.4mm external - Front Spoke Pattern: Two-cross/Radial (2:1) - Rear Spoke Pattern: One-cross/Two-cross (2:1) - Spoke Count: 21 front, 24 rear - Spoke Type: DT Swiss Competition Race T-head - Nipple Type: DT Swiss Pro LockBrass hexagonal - Front Hub: Roval AFD1, Centerlock, sealed cartridge bearings, quick-release or 12mm thru-axle end cap - Rear Hub: Roval AFD2, Centerlock, sealed cartridge bearings, DT Swiss 350 internals, 11-speed, quick-release or 142x12mm thru-axle end cap - Assembly Method: Hand-built - Extras: Roval steel quick-releases, Roval tubeless plugs and valves, Front quick-release & 12mm endcaps, Rear quick-release & 142x12 thru-axle endcaps - Total Wheelset Weight: 1,515g

A 50mm-deep, 1465-gram clincher wheelset that's race-ready and wallet-friendly. - Rim Type: Carbon clincher, 2Bliss-Ready - Rim Material: Carbon - Braking Surface: Carbon Fiber - Brake Track Height: 12mm - Rim Depth: 50mm - Rim Width: 20.7mm internal, 29.4mm external - Front Spoke Pattern: Radial - Rear Spoke Pattern: Radial/Two-cross (2:1) - Spoke Count: 16 front, 21 rear - Spoke Type: DT Swiss Competition Race T-head - Nipple Type: DT Swiss Pro LockBrass hexagonal - Front Hub: Roval AF1, sealed cartridge bearings - Rear Hub: Roval AF1, sealed cartridge bearings, DT Swiss 350 internals, 11-speed - Assembly Method: Hand-built - Extras: Roval steel quick-releases, Roval tubeless plugs and valves, SwissStop Black Prince brake pads

The age of traction, stability, and speed has arrived, and its name is the Roval Traverse 38 SL Fattie 650b wheels. They feature 148mm rear and 110mm front axle widths, but to turn them into descending machines is the 38mm internal rim width. The extra width also allows for more tire volume, which means increased suppleness in the ride quality. And not only this, but the ample width also better supports the tire, meaning that you'll experience less "burping" when riding tubeless. These wheels also include the Roval tubeless plug system, which is an easy and super lightweight solution for tubeless setups. At the front hub, you'll get a 15x110mm thru-axle (end cap options included), and at the rear, the hub features DT Swiss internals for quick engagmenet. And to top everything off, these wheels are hand-built to ensure a painstaking attention to detail. -Please note that this 148 version is exclusively designed for use with bikes designed with 110x15mm front axle and 148mm rear axle standards.

The Roval CLX 32 Disc full-carbon clincher is the perfect performance disc wheel; light, stiff, and fast. The wide internal rim width provides an optimum tire profile for precise handling, stiffness, and aerodynamics. The Center Lock hub makes this an ideal wheel for the muddiest cross-race or fast paced ride. This wheel offers a non-SCS rear hub for traditional QR or 12mm thru-axle compatibility.

The Roval CLX 32 Tubular wheels are some of the lightest carbon wheels ever made, but this doesn't come at the expense of fundamental performance. Instead, painstaking engineering and lab testing helped them achieve a 490-gram front and 665-gram rear wheel that's tough enough for cyclocross racing, yet light enough for the demands of a GC climber. The low inertia and ample stiffness help the wheel accelerate and change direction on a dime. We didn't skimp on aerodynamic benefits either, despite this wheel's low rim profile. The CLX 32 was engineered in CFD around a 26mm-wide tire shape, and honed in Roval's very own Win Tunnel, in order to be as aerodynamic as some rims almost twice its depth. Meanwhile, Roval aero hubs and CeramicSpeed bearings complete the fast-engaging ensemble. Truly, the CLX 32 ushers in a new era of lightweight performance road wheels.

Developed in Specialized's Win Tunnel and designed to interface with the world’s fastest tire, the S-Works Turbo, the Roval CLX 64 is the fastest road race wheel/tire system Specialized has ever developed. The 20.7mm tubeless-ready internal rim width further increases tire volume, in turn creating a larger contact patch. Specialized's wheel system comes complete with the S-Works Turbo tire, which measures 24mm wide for enhanced stability and traction in corners and on descents. Throw these on and watch the competition flail helplessly in your wake.

A wide internal rim width provides an optimal tire profile for incredibly precise handling and stiffness.

First came our CLX 64. Then the 32s. And after racking up multiple wins in Grand Tours, Worlds, and everything in between, we knew that our best bet was to take the line to new heights, or well, new depths. We needed to design one wheel that was a true quiver killer. One wheel that had all the aerodynamic benefits of the 64 in a package that climbed like the 32, and that’s where the all-new CLX 50 comes in. When we set out to create the CLX 50, we had clear goals in mind—create wheels that are 48 to 54mm deep, aerodynamically optimized, ultra-wide, and under 1400 grams. This meant that they'd have to borrow some weight savings techniques that we developed for the CLX 32, while taking some aero guidance from the CLX 64, if we were going to create what we like to call “the unicorn wheel." Even though the CLX 50 is similar in weight to many wheels in the “lightweight” category, aerodynamics came at the forefront of the development. With this, we jumped headlong into Computational Fluid Dynamics computer modeling to arrive at various rim shapes that could make the CLX 50 as fast and light as possible. It took a while, but we narrowed the rim shape down to three contenders that were then CNC machined into rims, built into wheels, and put into the Win Tunnel. The tubular version of the CLX 50 also features a rim design that differs from the clincher version, in order to be aerodynamically optimized for tubular tires. And to prove our concepts, we tested every wheel, ours and the competition's, with a 24C tire (measuring 26C), as tires can drastically affect testing. We chose a modern-width tire to design our rims around, because they not only allow for less tire pressure (which results in more comfort and less rolling resistance) but are also just as aerodynamically efficient when paired with the correct rim width. After finding the optimized rim shape that supported our svelte weight requirements, we opted to lace this rear rim, via 21 DT Swiss Aerolite spokes, to our Aero Flange (AF) hub with the legendary CeramicSpeed bearings and DT 240 hub internals. And when it was time for final testing validation, we were left with a 50mm-deep, 1230-gram tubular wheelset that's not only ~ 275 grams lighter than the competition’s similar depth wheels, but is also measurably faster in every conceivable test than each wheel in its category.

Developed in Specialized's Win Tunnel, and designed to interface with the world’s fastest tire, the S-Works Turbo, the Roval CLX 64 Disc is one of the fastest disc brake road race wheel/tire system ever developed. The SCS hub allows for a proper chainline on short chainstay performance road and 'cross bikes. This wheel system comes complete with the S-Works Turbo tire which measures 24mm wide for enhanced stability and traction in corners and on descents. This rear wheel uses an AFD1 SCS Center Lock aero hub that's compatible with a QR or 12mm thru-axle.
