The trails in our neck of the woods get pretty hairy, pretty fast, so we've found them to be the perfect testing ground for fast and tough wheels like our Traverse 29 Carbon. The steep climbs and descents helped inspire some pretty radical designs, and most importantly, left us with no doubt that these wheels will exceed your expectations. Let's talk about those expectations. They include everything from the ability to stay true after launching off drops to being light enough to efficiently pedal to the top of a climb—and they all begin with the rim. Our engineers knew they wanted carbon fiber, and with the inclusion of our Zero Bead Hook design, they were able to implement a continuous fiber layup across the sidewall and rim bed. And when paired with a whopping 30-millimeter internal rim width, you get a wheel that's super resilient to impact with low rolling resistance and incredible traction. You'll also find that it helps prevent "burping" during hard cornering while making tubeless set up quick and easy. A wider rim does a variety of things for ride performance—it better supports the tire for increased confidence and grip, and it affords you the ability to run lower pressures to aid in the aforementioned, as well as spreading impact out over a larger surface area to reduce the risk of damage during impact. And when you combine this girth with the notoriously fast rolling 29 platform, you're left with an incredibly stiff, quick to accelerate wheelset that climbs just as well as it shreds descents. After designing the perfect trail rim, we kept our lightweight and durable design properties in mind with the wheel build, hand-lacing the rims DT Swiss 350 Classic hubs via 28 (front) and 28 (rear) DT Swiss Competition Race spokes and brass Pro Lock nipples. Inside, you'll find sealed cartridge bearings and a 36t quick engagement ratchet system for quick accelerations. We also wanted to ensure that each wheel was built correctly, and we found that this could only be achieved by hand. Machines, we found, have a tendency to miss little mistakes that humans would otherwise catch. Finally, with the 15x110 / 12x148mm variant, you receive all of the benefits that Boost spacing offers. By increasing the width of the front and rear hub flanges, and in turn, increasing frame and fork clearance and stiffness, you obtain a stiffer, stronger, and more durable system at a minor weight penalty. Each wheelset comes packaged with a SRAM XD driver, 11-speed freehub, and a tubeless valve stem in order to make tubeless set-up a touch easier. *Please note that Shimano freehubs are sold separately. - Rim Type: Carbon clincher, 2Bliss Ready, Zero Bead Hook design.

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

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.

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 321 disc turns conventional design on its head, creating the fastest wheel available. 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 long haul. 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 new-to-category 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 out of the box and comes with a padded wheel bag, quick-release, tubeless valve, and SwissStop Black Prince brake pads. 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: Carbon clincher, 2Bliss Ready - Rim Material: Carbon - Braking Surface: Carbon Fiber - Brake Track Height: 12mm - Rim Depth: Solid Disc - Rim Width: 19mm internal, 27.3mm external (at brake track) - Rear Hub: Roval Disc, CeramicSpeed bearings, DT Swiss 240 internals, 11-speed - Assembly Method: Handmade - Extras: Roval padded wheel bag, Roval steel quick-release, Roval tubeless valve, SwissStop Black Prince brake pads, Roval valve pocket covers - Weight: 1000g
