700c, 27-Inch & 650c

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. Even though the CLX 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 CLX 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. After finding the optimized rim shape that best supported our svelte weight requirements, we opted to lace the rims to our Aero Flange (AF) hub, via 24 DT Swiss Aerolite spokes, which features the legendary CeramicSpeed bearings. 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, 770-gram rear wheel that's not only significantly lighter than the competition’s similar depth wheel, but is also measurably faster in every conceivable test than each wheel in its category.

Slice through the wind on Roval's Rapide CLX 40 Wheelset. They feature 40mm-tall aero carbon rims, and DT Swiss Revolution straight-pull spokes laced to sealed ceramic cartridge bearings Roval hubs. The rear hub is adorned with DT Swiss's renowned 240 star ratchet internals. The wide, carbon rim provides a round tire profile and greater lateral stiffness for precise handling. This feathery, 1240-gram wheelset spins up with ease so you can bolt out of corners and breeze up the climbs. With your favorite tubular tires, these wheels roll as smooth as silk.

Equip yourself with the wheel that carried Tony Martin to a World Championship and reach the pinnacle of your own potential. Zipp’s Super-9 Carbon Clincher Disc underwent extensive fluid dynamic modeling, wind-tunnel testing, and relentless refinement so you can enjoy no-holds-barred aero domination. With a variance in width of just a single centimeter from rim to hub, the Super-9 is almost invisible to the wind. Plus the wide rim creates a virtually seamless integration with the tire, increasing aerodynamics and allowing wider tires run at a lower pressure. This diminishes rolling resistance, increases rider comfort, and reduces the chance of pinch flatting.

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.

Zipp’s first product almost three decades ago was a disc wheel. It’s at the heart of their heritage. Now, Zipp is pioneering the next generation of disc wheel, the Super-9 Disc-brake Disc. The Super-9 Disc itself, handmade at Zipp's factory in Indianapolis, USA, optimizes supreme aerodynamics, power transfer, stiffness, lightweight and durability.The Super-9 disc has an unassuming profile. It borrows from the perimeter shape that makes the Sub-9 so fast it can actually generate forward lift, but in place of the Sub-9's toroidal bulge, the Super-9 remains flat from its widest point all the way to the hub. This relatively simple-looking shape results in a wheel that's as fast as the Sub-9 but stiffer than any other Zipp disc. Braking on modern time trial and triathlon bikes often has been a challenge. The superior performance of disc brakes changes all that with greater stopping power and more precise speed modulation, all with less hand effort than required by traditional brakes. That means greater confidence in corners, descents, and on technical courses. The disc brake version of the Super-9 disc retains the light weight of its rim-brake counterparts. - Includes: Aero Stainless Steel Black Quick Release, 10-speed hub spacer, Platinum Pro EVO Brake Pads, Valve Extender, Valve Adaptor, Valve Decal

Now that it's available in a disc-brake version with our UST Road Tubeless technology, it's even smarter. For a reasonable price, you get all performance and dependability that go with the Ksyrium name plus the added benefits of tubeless, including less rolling resistance, a smoother ride quality, and a reduced risk of punctures. There's no other road tubeless system that's easier to use. Our UST rims and tires make it simple to change, mount, and inflate tires. The wide rims (19mm internal) are optimized for 28mm tires (and still compatible with 25mm), perfect for tackling a variety of road terrain with efficiency and control. Our patented ISM (Inter Spoke Milling) technology reduces weight for fast climbing and instant acceleration. The system is engineered specifically for disc brakes, with plenty of lateral stiffness for precise handling and total axle and freewheel compatibility. If you're looking for an upgrade that can immediately boost your road bike's performance, look no further.
