Make your WTB rims air tight and ready for tubeless use with WTB's TCS Rim Tape. This tape covers the spoke holes and can be used as a lightweight rim tape in any rim. Available in 11-meter (covers 5 rims) and 55-meter rolls (covers 27 rims).

Surly Rim Strips have one job and they do it well. They cover the cutouts in your rim and — if you're running a tube — they protect it from spoke heads and other sharp matter (okay, so maybe they have TWO jobs but they do them both really well.) Rim strips are crucial and should be used with all Surly rims. Ours come in an array of colors so you can really "express yourself." Surly Rim strips are available in two different materials: PVC and Nylon. PVC is great if you plan on only running tubes. However, if there's any part of you that wants to try this tubeless thing you've been hearing about, Nylon strips are just the ticket. They're thinner and offer minimal stretch so they stay put and lay nicely inside the rim to provide a secure seal. Plus, they're lighter which we all know means you'll go faster… maybe.

In the early design phases of our Traverse Fattie 29, 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 proper, 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. We also wanted to ensure that each wheel was built correctly, so we built them by hand. Each wheelset comes packaged with a SRAM XD-driver and a tubeless valve stem in order to make tubeless set-up a touch easier. Please note that Shimano freehubs are sold separately.

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. - Assembly Method: Hand-built - Braking Surface: Disc brake only - Extras: Roval steel quick-releases, Roval tubeless plugs and valves, Front quick-release, 12mm endcaps, Rear quick-release, 142x12 thru-axle endcaps - Front Hub: Roval AFD1, Center Lock, sealed cartridge bearings, quick-release or 12mm thru-axle end cap - Front Spoke Pattern: Two-cross/Radial (2:1) - Nipple Type: DT Swiss Pro LockBrass hexagonal - Rear Hub: Roval AFD2, Center Lock, sealed cartridge bearings, DT Swiss 350 internals, 11-speed, quick-release or 142x12mm thru-axle end cap - Rear Spoke Pattern: One-cross/Two-cross (2:1) - Rim Depth: 50mm - Rim Material: Carbon - Rim Type: Carbon clincher, 2Bliss-Ready - Rim Width: 20.7mm internal, 29.4mm external - Spoke Count: 21 front, 24 rear - Spoke Type: DT Swiss Competition Race T-head - Total Wheelset Weight: 1,515g

When we set out to create a lightweight wheelset, we didn't want it to be "just another climbing wheel." We wanted to provide the lightest wheelset out there with the aerodynamic attributes of something twice its depth. One wheel that'll get you to the base of a climb quickly and up it as efficiently as possible, yet still be strong enough for day-to-day abuse. It was a tall order, but in the end, the CLX 32 gave us more than what we asked for. Our design process started with a low overall weight at the forefront, as we knew what weight we could hit with the information and technology we had available. With that weight in mind, we then turned our focus to aerodynamics and began an iterative process of designing and testing over 150 individual rims to find the optimal shape. These innumerable Computational Fluid Dynamics (CFD) models, Win Tunnel hours, and shots of espresso left us with a 32mm-deep shape that boasts more logged wind tunnel time than any other wheel in its category. Once we found the most aerodynamic shape, at the 32-millimter depth, we came back to the weight focus and proceeded to experiment with over 40 different layup methods to reach our desired weight. And this made the CLX 32 lighter and faster than every other competitor in the lightweight wheel category. For the CLX 32 clincher front, we mated the rim to our Aero Flange (AF) series hub with DT Swiss Aero spokes in order to create the best overall wheel system. This resulted in a 553-gram, 21mm-wide (internal width) front wheel with an extremely low inertia value. In cycling, inertia relates to the amount of force it takes to accelerate or decelerate, so wheels that are built with lightweight rims, like the CLX 32, result in a lower inertia value that creates a lively wheel that allows you to accelerate, decelerate, and change direction with less effort. But why so wide? Well, additional width does three primary things for a rim, it provides additional structural strength, it allows for a clean rim and tire interface when using wide tires (resulting in enhanced aerodynamics and faster rolling properties), and it better supports the tire in hard cornering. This boosts both predictable grip and confidence when things get twisty on the descents. Each CLX 32 clincher front wheel also employs the legendary CeramicSpeed bearings and comes with our padded wheelbag, quick-release, tubeless plugs, tubeless valve, and SwissStop Black Prince brake pads. - Assembly Method: Hand-built - Brake Track Height: 12mm - Braking Surface: Carbon fiber - Extras: Roval padded wheelbag, Roval steel quick-release, Roval tubeless plugs and tubeless valve, SwissStop Black Prince brake pads - Front Hub: Roval AF1, CeramicSpeed bearings - Nipple Type: DT Swiss Pro Lock hexagonal - Rim Depth: 32mm - Rim Material: Carbon - Rim Type: Carbon clincher, 2Bliss Ready - Rim Width: 20.7mm internal - Spoke Count: 16 - Spoke Pattern: Radial - Spoke Type: DT Swiss Aerolite T-head - Weight: 550g

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 Disc, 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, take some aero guidance from the CLX 64, and keep all of the disc brake benefits that we've come to love if we were going to create what we like to call "the unicorn wheel." Why discs you ask? With our disc-specific rims, we ditch the brake track, making for a stronger, more impact-resistant rim. This way, you get a disc-specific carbon layup that optimizes stiffness, a weight as close to its rim-brake brethren as possible, and incredible brake modulation and power in all conditions.

This way you get a complete, superior wheel system—not just a quick rim. And at the end of the day, it all amounts to a 50mm-deep, 1415-gram clincher disc wheelset that's not only ~300 grams lighter than the competition’s similar depth wheel, but is also measurably faster in every conceivable test than each wheel in its category.
