Feel your bike come alive on the open road with the new Alpinist CLX II-the lightest, best-handling clincher wheels we have ever made. Hyper-responsive acceleration, magic in the corners, sublime over rough roads, all elevated with the performance of a tubeless system. There's no room for a single excess gram whether you're chasing summits or ride quality because perfection is only achieved when there is nothing left to take away. It takes more than a lightweight rim to deliver the incredible reactivity and handling of the tubeless Alpinist CLX II. The wheelset is designed as a system with our engineers controlling and testing every part of that system-hubs, rims, spokes, lacing-and developing it hand-in-hand with Specialized Tubeless tires. The result is a 1250-gram tubeless wheelset with otherworldly ride quality. The Alpinist CLX II utilizes a hooked rim (allowing for real-world riding pressures up to 110psi, if that's your thing) for secure tire bead retention and an easier set up and mounting experience than ever before. All in a wheel that almost doubles current industry impact standards while managing to achieve the lightest weight possible. Our all-new LightAF hubs are the spinning heart of the Alpinist CLX II.

Zipp's 303 Firecrest Tubeless wheels are designed for the real world—a world of imperfect conditions, varying road surfaces, and elements where the bottom line is simple: efficiency = speed. They're faster, lighter, and more capable over varied terrain—whether the surface is pavement in all its conditions or no pavement at all. Deeply rooted in Zipp's drive to conquer the Spring Classics, the new 303 Firecrest is remade with a purpose-made approach for the demands of modern road bikes. When it comes to going fast on a bicycle, efficiency means reduced wind resistance, rolling resistance, rider fatigue, and weight. The 303 Firecrest Tubeless Disc-brake was designed using real-world direct measurements (vs. primarily wind tunnel or computer simulation). The results were huge. Its rim is slightly more bulbous in design than its predecessor, with a 32mm outside width, a 25mm internal width, and a 40mm rim depth. The profile provides low drag and an improved transition between rim and tire, boosting aero efficiency on the road. The wide rim stance also features less tire deflection for reduced rolling resistance. The combination of the wider tire, increased tire volume, and lower tire pressure helps to reduce rider fatigue by smoothing out the ride over imperfect pavement and road conditions—the tire and wheel system absorbs the shaking, not the rider. At the center of the 303 Firecrest Tubeless is a versatile and durable new hubset, the German-engineered ZR1 DB. This hubset features 66 points of engagement for quicker response. The 303 Firecrest Tubeless wheels are for dedicated cyclists who aspire to the latest in technology. They're for those who compete in races, against peers, or simply to conquer personal limits. - New Zipp graphics and cosmetic identity that scream speed - Versatile endurance wheelset for the modern road bike with tubeless and hookless rim profile - Lighter weight than its predecessor, making it nimble and fast - Tubeless Made Easy, optimized tire bed sign allows for simple tool-free installation and removal with no need for an air compressor to seat the tire. - Ultra-wide 25mm rim profile creates a better tire interface to be fast on or off the road - 40mm rim depth makes a light and aero wheel in every situation - Ships with 12mm end caps - Center Lock rotor interface (lockring included)

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 rear clincher, we mated the rim to our Aero Flange (AF) series hub with DT Swiss Aero spokes to create the best overall system. This results in a 730-gram, 21mm-wide (internal width) rear 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 rear 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 - Nipple Type: DT Swiss Pro Lock hexagonal - Rear Hub: Roval AF1, CeramicSpeed bearings, DT Swiss 240 internals, 11-speed - Rim Depth: 32mm - Rim Material: Carbon - Rim Type: Carbon clincher, 2Bliss Ready - Rim Width: 20.7mm internal - Spoke Count: 24 - Spoke Pattern: Radial/Two-cross (2:1) - Spoke Type: DT Swiss Aerolite T-head - Weight: 730g
