Wheels

Zipp's 303 S Tubeless Disc Brake wheelset provides today's cyclists the versatility they demand with the speed they crave. Expanding greatly on its heritage of conquering the Spring Classics, this 303 wheelset maintains its ideal-for-every-terrain 45mm rim depth but adds a significantly wider internal width to provide greater performance and ride quality in almost every measurable way. This wheelset is tubeless for disc-brake bikes, allowing the ability to run wide tires at lower pressures for race-ready speed on or off the pavement. The 303 S is among our lightest wheelsets, optimized for top aero performance with a 28mm tire but capable of handling gravel tires up to 50mm wide. - Wide rims optimize tire profile to allow lower tire pressure, especially with tubeless. The result is a larger contact patch for increased grip and confident cornering, descending, and handling in wet conditions. - Lower tire pressures and larger volume provides a compliant ride with fewer vibrations. - Significant watt savings when running larger tires at lower pressure. - Wide, hookless rims create a seamless transition to the tire, reducing drag. - Fastest with 28mm, but fits wide gravel tires as well - New Zipp graphics and cosmetic identity that scream speed

Born on the World Cup, destined for your local trails. We poured World Championship-winning engineering into developing an all-new alloy for these Control wheels. To increase the new material's durability, we customized our shot peening process-where metal projectiles are shot at the alloy to increase its strength-meeting the precise demands of our XC riders. If that wasn't enough, to eliminate creaking and reduce weight, individually customized sleeves are chosen to bond every single rim. The result is a wildly over-engineered, trail-ripping, best-of-the-best, aluminum wheel: held to the same standards as our highest-end Control SL carbon components. Whether you are looking for a solid set of training wheels that will handle it all, or a big upgrade from entry level wheels, Roval Control Alloy is the go-to wheel. With creak-free hoop construction that's laced to high-performance and proven DT Swiss hubs, you can tap into a wheelset born from World Cup technology that's ready for all riders. - Rim: Control Alloy Asymmetric, 6013 Alloy Shot-Pened, 29", Disc Brake, Zero Bead Hook Design, Tubeless Compatible, Compatible with Tire Inserts - Rim Details: 19mm Depth, 31mm External Width, 27mm Internal Width - Hub: DT Swiss 350 Straight-pull 6-bolt, Star Ratchet 36t internals (10 degs) , 110x15mm & 148x12mm, Sram XD Freehub (Convertible freehub ) - Bearing Type: DT Swiss Sealed Steel Cartridge Bearings - Spokes: Sapim D-Light Straightpull, Front: Two-cross (1:1) 28 count, R: 304mm, L: 304mm—Rear: Two-cross (1:1) 28 count, DS: 304mm NDS: 304mm - Nipple: Sapim Secure Lock Double Square Alloy Blk, 2.0,18mm, 16cNm - Tire Size: 1.9"—2.6"—Max Pressure: 1.9"-2.3": 40psi, 2.35"-2.5": 35psi, 2.51" -2.6": 30psi - Weight: Wheelset 1,648g, Front 768g, Rear 880g (excluding 15g, tubeless rim tape and tubeless valve) - Assembly Method: Hand-built - Extras: Roval Tubeless Rim Tape and Tubeless Valve, Spare Spoke & Nipple Kit, 19 and 31mm OD Endcaps, Lifetime Warranty System Weight Limit: 275lbs / 125kg

At the helm of taking traction, stability, speed, and stiffness to new heights stands the Roval Traverse Fattie 38 27.5 wheels. And while, yes, they feature a lightweight alloy rim and a quality build, what turns them into descending machines is the 38mm internal rim width. Let's find out why. The reason behind this is easy: Aside from the lightweight and ultra-rugged E5 alloy construction, the combination of the rim width with wider hub flanges creates an increase in plus-sized tire volume. This means that you get more suppleness in the ride quality. But not only this, the ample width also better supports the tire, so you'll experience less "burping" when riding tubeless, as well as a drastic increase in traction. 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. These aren't just a one-trick pony, though. At the front hub, you'll get a 15x110mm thru-axle (end cap options included), and at the rear, the 148mm hub features DT Swiss internals for lightning-fast engagement and acceleration. And to top everything off, these wheels are hand-built to ensure the perfect tension and a long lifespan. Whether you've just picked up a new 27.5+ bike, or you're curious to try out high-volume tires, like a 2.8", on your Boost™-spaced 29er, the Traverse 38 Fattie 27.5 wheels will leave you impressed after the first spin.

Wherever the trail leads, SRAM's Roam 30 is ready to go. The 25mm wide rims give big tires the support they deserve for outstanding cornering control, and the rims are durable enough for day-after-day sessions, yet light enough for race day. And, the Roam's great features continue with SRAM's Solo Spoke design that uses one spoke length to fit the entire wheel, and quick-release skewer and 15mm thru-axle end caps that can be interchanged without tools.

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.

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.
