Specialized Roval Traverse Carbon 148 29-inch Wheelset
$1,199.99
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.

Roval Roval Control 29 Carbon 148
$1,199.99
It’s not often that “affordable” and “carbon” appear in the same sentence, but our Control 29 Carbon wheelset was designed to change that. Utilizing many of the same techniques used in the development of the SL iteration of the Control 29, these wheels provide the lightweight XC performance you need at a more attainable price. Creating a successful XC wheelset isn't as easy as you might think. Often times, keeping a wheel light, stiff, and strong requires an unlimited budget. So when we were asked to create a wheel that had low inertia and weight, but was also affordable, strong enough to take on rocks and roots, and wide enough to optimize traction and rolling resistance, we knew that we had our work cut out for us. We started with the notion of keeping these wheels as close to their SL brethren as possible. And with this, we explored what made the SLs so awesome in the first place, and then we implemented nearly every aspect of them. Starting with the rim, we kept our renowned Zero Hook Bead that allows for continuous fiber layup across the sidewall and rim bed. We then paired it with a wide 25-millimeter internal profile that makes it resilient to impact and creates a tire profile that’s conducive to low rolling resistance and incredible traction. On the trail, these technical traits translate to a wheelset that many XC riders have grown to love—quick accelerations on punchy climbs, swift stopping that lets you leave braking till the last second, and unprecedented reliability. Combine this with the easy to set up our 2Bliss Ready system and you have a reliable XC wheelset that’s as easy to climb on as it is to work on. To go along with the rim, we made sure to keep the lightweight, reliable, and affordable features in mind when building the wheelset, so we took DT Swiss 350 Classic hubs (15x110mm thru-axle front / 12x148mm thru-axle rear) and hand-laced them with 28 DT Swiss Competition Race spokes. Finding hand-built wheels is becoming more and more difficult, but we're fully invested in the power of the human touch. When a wheel is machine-built, there are certain margins of error that are built into the system that result in inconsistencies. With a real person building your wheels, however, you're sure to get a wheelset that's free of imperfections. - Rim Type: Carbon clincher, 2Bliss Ready, Zero Bead Hook design, black graphic under clear coat. - Rim Material: Carbon fiber - Rim Width: 25mm internal - Front Spoke Pattern: Two-cross - Rear Spoke Pattern: Two-cross - Spoke Count: 28h Front, 28h Rear - Spoke Type: DT Swiss Competition Race J-bend - Nipple Type: DT Swiss Alloy Pro Lock hexagonal - Front Hub: DT Swiss 350 Classic, 28h, 15x110mm thru-axle, 6-bolt, includes 15x110mm 19mm OD end caps. - Rear Hub: DT Swiss 350 Classic, 28h, 36t quick engagement ratchet system cassette, 12x148mm, includes SRAM XX1 XD freehub. - Includes 31mm OD end caps for front hub - Bearing Type: Sealed cartridge - Every wheel includes a tubeless valve stem in order to make tubeless set-up a touch easier. - Assembly Method: Hand-built - Total Wheelset Weight: 1610g

Stan's NoTubes Baron S1
$479.00
Stan’s S1 wheelset line brings patented tubeless technology to an even wider range of riders. Built for long life, low maintenance, and outstanding value, the S1 series wheels feature 6061 series alloy rims and are available in six different widths suited to a wide range of tire sizes and riding styles. With an emphasis on value and durability, the S1 alloy wheelsets join a mountain wheel line-up that currently includes Stan’s successful MK3 premium alloy wheels and innovative Valor and Bravo carbon series wheelsets. While MK3 wheelsets are built to balance strength, light weight, and stiffness, S1 wheelsets focus on maximum strength and durability. The deeper profile and thicker walls of the S1 rims result in a 50-70g weight increase over MK3 rims, but offer greater impact strength for an even wider range of use. “The new S1 series wheels were developed from rims ridden in Redbull Rampage and raced on the World Cup DH circuit for years,” said Creative Director, Chris Currie. “The goal was to take everything we’ve done for tubeless technology, and put it into a truly bombproof and affordable wheel.” Designed according to Stan’s WideRight rim and tire fit system, S1 series wheelsets are available in six different rim models, with internal widths ranging from 23mm to 38mm. Combined with Stan’s low-profile, high-volume Bead Socket Technology rim design, these widths let the new S1 range accommodate tires from 2-inch to 3.5-inch. All S1 wheelsets are built with 32 spokes front and rear, Sapim’s proven Race spokes, Secure Lock brass nipples, and Stan’s faster-engaging Neo hubs. Hubs are available to fit most axle systems, including Boost. The S1 series includes reinforced versions of the classic Crest, Arch, and Flow--names already familiar to fans of Stan’s tubeless rims. In addition to the Crest S1, Arch S1, and Flow S1, three entirely new wider wheelsets will be available. The Sentry S1, Baron S1, and Major S1 bring Stan’s patented Bead Socket Technology to Plus bikes.

Specialized Roval 321 Disc - Disc Brake 700c Rear
$2,500.00
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
