Feel your bike come alive on the open road with the new Alpinist CL II, featuring the lightest, best-handling clincher rims we have ever made, elevated with the performance of a tubeless system. The brand new Alpinist CL II now brings mountain-taming performance slightly closer to earth with a carefully selected build designed to let riders take full advantage of the low rim and spoke mass. The Alpinist CL II utilizes the same rim as the alpinist clx ii. They react to even the slightest increase in power with immediate acceleration and carve the purest lines in the corners, yet they can also handle almost double the impact standards of every certifying body. The result is a 1375-gram tubeless wheelset with an otherworldly ride quality designed for real-world road pressures. The Alpinist CL II utilizes components curated to keep you rolling and rolling fast. The DT Swiss 350 hubs, featuring their star ratchet drive system, are reliable and easy to service, while 24 DT Swiss comprace straight-pull spokes front and rear, laced to the rims with their alloy pro lock nipples, are synonymous with reliability and can be obtained at any bike shop. The reduced rolling resistance of a tubeless setup is undeniable, as are the benefits of improved handling and incredible puncture protection. It took the most extensive and demanding engineering and testing program we've ever undertaken. As a result of this extensive development, the Alpinist CL II features a hooked rim that can handle a huge range of pressures up to 110psi and offers an easier set up and mounting experience than ever. - Rim: Alpinist CLX Carbon Clincher, 700c, Disc Brake, Tubeless - Rim Details: 33mm Depth, 27mm External Width, 21mm Internal Width - Hub: DT Swiss 350 Straightpull Center Lock, Star Ratchet 36t internals (10 degs), 100x12mm & 142x12mm, Shim.

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

Performance Upgrade Made Easy The C38 brings carbon fiber high performance to the real world. It's a versatile all-rounder equally at home crushing gravel washboards and summiting alpine passes. Optimized for use with modern wide tires, providing the right amount of sidewall support to facilitate surefooted handling in all conditions, the C38 wheelset is a great handling, lively climbing, robust all-road performer that also aerodynamically outperforms many deeper, aero-specific rims that cost twice as much. Carbon wheels are a true performance upgrade to any bike, but too often the price tag puts them out of reach. The Rapide C38 shatters that barrier and brings a class-leading Roval carbon rim and DT Swiss reliability together to provide riders with the best performance carbon wheel per dollar.

Following directly in the tire tracks of the Terra CLX, the new Terra CL utilizes the same super-light, incredibly tough rim as our flagship wheel. It's a hook-bead, 33mm deep carbon fiber rim with a 25mm inner width that plays well with tubeless setup and allows you to mount tires anywhere from 28mm to 47mm wide at whatever pressure you feel like running. In a nod to accessibility, durability and real-world serviceability, we opted to use ultra-dependable DT Swiss 350 hubs and lace them to the rims with DT Swiss Competition Straightpull spokes. The net effect of these changes is a wheelset that is almost as light as our incredibly light Terra CLX, offering close to the same benchmark performance but with more easily sourced spokes in the event of some back-of-beyond carnage, all with a price tag that is about half that of our flagship product. - Rim: Terra CLX Carbon Clincher, 700c, Disc Brake, Tubeless Compatible - Rim Details: 32mm Depth, 30mm External Width, 25mm Internal Width; ERD 577mm - Hub: DT Swiss 350 Straight-pull Center Lock, Star Ratchet 36t internals (10 degs), 100x12mm & 142x12mm, Shim.

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
