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

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.

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 tough, nimble wheels like our Traverse 27.5 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 nimble and playful 27.5 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.

In the early design phases of our Traverse Fattie 27.5, we recognized that the number of aluminum wheels that had the prowess to both shred rowdy descents and to provide the efficiency required of our Northern California testing grounds' relentless climbs were far and few between. We also came to realize that trail riders expect certain features in a super nimble, send-it-ready wheelset. And for the price, we found that alloy hit many of these expectations, while also keeping enough jingle-jangle in your wallet for a post-ride beverage. 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. We took the traditional 19- to 23-millimeter standard and moved it out to what we found worked best in testing—a whopping 30mm “Fattie” width. A wide rim does a variety of things for ride performance—it better supports the tire for increased confidence and grip, it affords you the ability to run lower pressures, and it spreads impact out over a larger surface area to reduce the risk of damage. We also added our Zero Bead hook design to the mix, and this ultimately aids in preventing “burps” during hard cornering, while also making tubeless set up quick and easy. After developing what we found to be the perfect alloy trail wheels, we went farther down the perfection path, hand-lacing the rims to our own alloy hubs that allow for the same spoke length throughout the entire wheelset, via 28 DT Swiss Revolution J-Bend spokes and Pro Lock nipples. Inside our hubs, you'll find sealed cartridge bearings and DT Swiss 360 rear internals that'll keep you rolling smoothly for miles.

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.

When speed is the ultimate goal, Specialized's S-Works Turbo Track Tubular is the answer. Extremely low-rolling resistance, superior traction, and the supple ride you expect from a pro-level tubular tire make the Turbo stand apart. This podium-worthy tire features a 290 thread-per-inch casing, BlackBelt flat protection, and a light, smooth riding latex inner tube. - 265 grams

The new Slaughter 2Bliss Ready tire has been designed for heavy-pedal, hard-pack riding—receiving vertically stepped knob shapes for more knob core stability and additional biting edges. Fast courses on hard-packed ground require a light, fast tire center to keep speeds high, but must also keep the speed through loose sandy corners and track well under hard braking. For these reasons, we've kept the high shoulder knobs. Our GRIPTON compound, meanwhile, improves high frequency damping, better attaching the tire to the ground over small bumps and rough sections alike. This also means that the low frequencies of the rolling tire deflections pass through unfiltered, leaving no energy to be absorbed and keeping the speeds high. - Casing: 60 TPI - Bead: Foldable - Butyl wrapped bead = 2Bliss Ready - Compound: GRIPTON - 29 x 2.3" PSI 25-50; approximate weight 810g

Riders have been asking for a tire that can enhance speed, while giving them plenty of confidence while cornering. And by lowering the center tread for high speed, yet keeping much taller side knob edges for secure braking and cornering, our Slaughter DH tire is all but guaranteed to get you to the bottom first. Plus, with butyl inserts at the tire bead, we even have you covered against pinch flats when the trail gets particularly rowdy. We've found it proper for rear usage, but it can be ridden as a front, too. - Casing: 60 TPI, Dual-Ply - Bead: Wire - Compound: Base 70a / Top 42a - Pinch Protection: Butyl Inserts at bead - 26 x 2.3", psi 25-50, approximate weight 1135g
