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 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.
At the helm of taking traction, stability, speed, and stiffness to new heights stands the Roval Traverse Fattie 38 27.5 wheels. And while, yes, they feature a lightweight alloy rim and a quality build, what turns them into descending machines is the 38mm internal rim width. Let's find out why. The reason behind this is easy: Aside from the lightweight and ultra-rugged E5 alloy construction, the combination of the rim width with wider hub flanges creates an increase in plus-sized tire volume. This means that you get more suppleness in the ride quality. But not only this, the ample width also better supports the tire, so you'll experience less "burping" when riding tubeless, as well as a drastic increase in traction. Along with light overall weight, stiffness, and durability, another top priority for the Traverse 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. These aren't just a one-trick pony, though. At the front hub, you'll get a 15x110mm thru-axle (end cap options included), and at the rear, the 148mm hub features DT Swiss internals for lightning-fast engagement and acceleration. And to top everything off, these wheels are hand-built to ensure the perfect tension and a long lifespan. Whether you've just picked up a new 27.5+ bike, or you're curious to try out high-volume tires, like a 2.8", on your Boost™-spaced 29er, the Traverse 38 Fattie 27.5 wheels will leave you impressed after the first spin.
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.
