Just wide enough, just light enough. At 30mm internal rim width the M 1700 SPLINE 30 works for tires ranging from slightly wide to quite wide, allowing it to attack the hardest terrain. But with a high-end build, butted spokes, patented alloy Pro Lock nipples and the benchmark Ratchet System hubs, it still comes in at a low weight. Low weight means it's very reactive to rider input. Reactive means fun, and fun is why we are all doing this, right?

Save energy on the climbs and rail rugged descents with higher speeds and total control. Mavic engineered the XA Pro Carbon to be significantly lighter and laterally stiffer than any aluminum wheel, but also retained the impact resistance and vertical compliance that gives Mavic Wheel-Tire Systems the ride quality they’re known for. The XA Pro Carbon is the lightest wheel system in its category (1490g for 27.5” and 1535g for 29”). So you know it helps you climb and accelerate faster, but where it really shines is in the way it handles rough and challenging terrain. Mavic engineered a wide 26mm hookless rim profile that’s fully UST Tubeless compliant for improved traction, puncture resistance and ease of use. These asymmetric rims are fine-tuned to optimize spoke tension and they use 24 double-butted steel spokes to find the sweet spot between lateral stiffness and vertical compliance. Hubs are 6-Bolt only and compatible with all current axle standards including Standard and Boost.

The Cosmic name represents that perfect balance between aerodynamics and weight. It’s about producing more speed on the flats while minimizing weight for the climbs. This all-new Cosmic Elite takes those qualities to the next level with Mavic's UST Tubeless Road Technology. Removing the tube reduces friction and allows you to run lower tire pressures with less worries about punctures. That makes it both faster and smoother, even on rough roads. It’s also engineered specifically for disc brakes, with steel-bladed straight-pull spokes that are stronger than traditional J-bend spokes, which are connected to Mavic's strongest hub platform running on smooth QRM bearings. Mavic's extensive wind tunnel testing led us to create a 30mm deep rim that optimizes aero performance and improves stability in crosswinds. The thickness of the rim wall is carefully tuned to hit the sweet spot between stiffness, strength and weight. Pedaling torque is efficiently transferred with Mavic's FTS-L freewheel system—light, smooth, stiff and easy to service. This hub easily converts from Shimano/SRAM to Campagnolo cassette. The Cosmic Elite Disc comes with Mavic's Yksion Pro UST tires, which deliver a very low rolling resistance to further enhance the efficiency of these wheels.

Designed for today's wider tires, the Sentry MK3's patented low-profile sidewall and lightweight 6069 alloy construction deliver width without the weight. Stan's patented BST rim design allows a tire to expand to its full volume without distorting its shape, and the 32mm internal width of the Sentry MK3 is more stable with 2.50"-3.00" tires. The result is less rolling resistance, more traction, and incredible handling. The Sentry MK3 is a great upgrade for anyone looking for the traction and control needed to take on even the most difficult trails.

The Ksyrium Elite road wheel has been a benchmark for reliability, light weight and versatility for more than a decade. This updated version makes it easier than ever to experience the benefits of riding tubeless. Integrated with Mavic's Yksion Pro UST Tubeless tires, the system makes installation, removal and maintenance simple and hassle-free. Eliminating the tube reduces friction in the system, which means less rolling resistance and higher speeds. You can also lower your tire pressure, which gives you a smoother, more comfortable ride plus added control on rough roads. You’ll also enjoy a reduced risk of punctures, so you can ride with confidence and push yourself farther. The rims are engineered with Mavic's patented Fore Drilling to form a stronger connection between the spokes and the rim. Isopulse lacing improves stability and boosts lateral stiffness while sprinting or climbing. Mavic's exclusive patented ISM 4D process strategically removes excess material from the rim while maintaining it around the spokes, where tension is applied. The wheel is available in three color options: gray on black; black with red highlights; and black with yellow highlights.

Equally adept on fast, rolling roads or mountain terrain, the Ksyrium Pro UST gives you all the advantages of Mavic's Road Tubeless system including less rolling resistance and a smoother ride quality. When paired with the new Yksion Pro UST tubeless tires, you get a perfect union between the wheel and tire, ensuring easy, hassle-free installation and removal thanks to Mavic's proven UST technology. And no tubes means no friction with the tire, so you roll faster using less energy. You can also lower your tire pressure for a smoother, more compliant ride, even on rough roads, with a reduced risk of punctures. Beyond the benefits of tubeless, all the other favorite features of this wheel stay the same. A wider rim shape (17mm internally) allows for an 18% increase in air volume for your tires. That extra volume gives you a more controlled and comfortable ride without compromising efficiency. The Zicral alloy spokes are stiffer, stronger and lighter than traditional stainless steel spokes. The Isopulse lacing pattern (radial lacing on the drive side) allows a more balanced spoke tension for a stiffer, more stable wheel. Fore drilling creates the strongest possible connection between rim and spokes, increasing stiffness by about 20%. Each part of the rim is precisely machined using just the right amount of material to provide stiffness and strength, while maintaining weight at only 400g. Total wheel weight is about 1420g.

The 303 brings a lot to the table, including heritage proven in the world's hardest races. At the center of the wheelset is Zipp's 77/177 hubset, which results in improved stiffness, durability, simplicity and versatility. The carbon wheel that helped pioneer the Firecrest rim platform for improved aerodynamics and crosswind stability also features the unspoken durability that has repeatedly won Paris Roubaix and the Tour of Flanders - Firecrest rim technology affords the rider more speed, more stability, and more strength. This technology offers stable, predictable handling, and the wider rim increases lateral stiffness while offering greater vertical compliance. Each Wheel Includes: - Zipp Tangente Quick Release Skewer - Zipp Tubeless valve – factory installed - Tubeless rim tape – factory installed - Valve core removal tool - Zipp 77D/177D thru-axle caps to fit 12x100, 15x100 and 12x142 dropouts
