Zipp makes the impossible possible with their 303 Firecrest Carbon Disc Brake wheels—they're equally at home on the flats as they are in the mountains. The 45mm-deep rims slice through the wind more efficiently than even many deep-section wheels thanks to their 28.5mm-wide dimpled rims. And, by creating a seamless junction between rim and tire, the increased width further reduces drag. The 303s climb with the best and re-accelerate out of corners like rockets since they barely register on the scale, which makes them a must-have on undulating terrain. The extra wide rim also allows running wider tires at lower pressures with less fear of pinch flatting, which boosts ride quality and comfort and reduces rolling resistance. Plus, Zipp's 77D/177D disc hubs gives you incredible stopping power in wet and dry conditions alike, and they're thru-axle compatible (sold separately) for jaw-dropping steering precision and power transfer. You also get Sapim's oustanding CX-Ray spokes.

Not all carbon rims are created equal. If your carbon rim is too stiff, you're losing speed and risking tire pinch flats. The Stan’s Crest CB7 rim with RiACT absorbs radial vibrations and damps impacts. It's a difference you can feel in the ride of the bike almost instantly. First introduced with Stan's legendary Valor rim, Stan's impact-absorbing RiACT technology has evolved to be more responsive and even more durable. The Crest CB7's new layup and rim shape allows for 10mm of radial compliance to absorb larger impacts. The new rim also matches the Valor's strength while using less material to save weight. And when it comes to the lateral stiffness needed for steering precision and control, the new CB7 layup delivers. Wider than the original Valor while still optimized for XC tire widths, the Crest CB7 keeps you in control and rolling faster. Stan’s backs up the technology in every Crest CB7 rim with one of the best warranties available, including lifetime crash replacement. Better by design, the Crest CB7 is the most advanced rim available for creating a lighter, stronger, more reliable, and faster rolling wheelset. - Designed for cross country racing and riding - Patented low-profile sidewalls and 23mm internal rim width - Ultra-light 325g (29") rim weight - RiACT system absorbs impacts and rolls faster - Bead Socket Technology for easier tubeless setup and the best reliability - WideRight rim design optimized for 2.00 - 2.25-inch tires

Stan’s S1 wheelset line brings patented tubeless technology to an even wider range of riders. Built for long life, low maintenance, and outstanding value, the S1 series wheels feature 6061 series alloy rims and are available in six different widths suited to a wide range of tire sizes and riding styles. With an emphasis on value and durability, the S1 alloy wheelsets join a mountain wheel line-up that currently includes Stan’s successful MK3 premium alloy wheels and innovative Valor and Bravo carbon series wheelsets. While MK3 wheelsets are built to balance strength, light weight, and stiffness, S1 wheelsets focus on maximum strength and durability. The deeper profile and thicker walls of the S1 rims result in a 50-70g weight increase over MK3 rims, but offer greater impact strength for an even wider range of use. “The new S1 series wheels were developed from rims ridden in Redbull Rampage and raced on the World Cup DH circuit for years,” said Creative Director, Chris Currie. “The goal was to take everything we’ve done for tubeless technology, and put it into a truly bombproof and affordable wheel.” Designed according to Stan’s WideRight rim and tire fit system, S1 series wheelsets are available in six different rim models, with internal widths ranging from 23mm to 38mm. Combined with Stan’s low-profile, high-volume Bead Socket Technology rim design, these widths let the new S1 range accommodate tires from 2-inch to 3.5-inch. All S1 wheelsets are built with 32 spokes front and rear, Sapim’s proven Race spokes, Secure Lock brass nipples, and Stan’s faster-engaging Neo hubs. Hubs are available to fit most axle systems, including Boost. The S1 series includes reinforced versions of the classic Crest, Arch, and Flow--names already familiar to fans of Stan’s tubeless rims. In addition to the Crest S1, Arch S1, and Flow S1, three entirely new wider wheelsets will be available. The Sentry S1, Baron S1, and Major S1 bring Stan’s patented Bead Socket Technology to Plus bikes. Arch S1 Wheelset - Use: Trail and Enduro - Internal Rim Width: 26mm - Optimal Tire Size: 2.25 to 2.5-inch - Hubs: Stan’s Neo 32-hole Front, 32-hole Rear - Spokes/Nipples: Sapim Race Black 2.0/1.8/2.0mm, Secure Lock Brass Silver Nipples - Wheel Sizes and Weights: 27.5-inch (1,882g) and 29-inch (1,974g)

The CLX 64 Track Tubular was brought to life under the Allez Allez team at the 2016 Red Hook Crit. Along these lines, you get all of the unrivaled aero performance of the CLX 64, albeit with DT Swiss track hubs and Aerolite spokes, for a stiff, smooth, and most importantly, fast ride on the boards. One of the first questions we get about the CLX 64 is, “Why 64mm instead of 65mm?” To put it simply, it's because 64mm tested faster than 65mm. One millimeter—that's how deep our testing goes. Having an in-house wind tunnel allows us to run every possible variation, and after two-years of development, 80 variations in rim design, and nearly 300 hours of Win Tunnel testing time studying tire and frame interactions, we found 64mm to be the fastest iteration for normal riding conditions. In fact, it's even faster than the 80-plus-millimeter-deep wheels they were tested against. Being able to use a shape that’s nearly 20mm shallower than the competition, yet just as low in drag, makes for a wheel that has drastically less side force and steering torque. This translates to less buffeting and more confidence in even the gustiest winds. Another positive of a shallower rim depth is the reduction in weight that follows using less material. Many deep carbon wheels feel “slow” due to their high inertia value. What's that? Inertia is the amount of force it takes to accelerate or decelerate, and wheels that are built around heavier rims lack the liveliness that many riders crave. Being over a half-a-pound lighter than the other wheels in its aero category, the CLX 64 accelerates, decelerates, and changes direction with less effort.

Campagnolo's Eurus wheels are tailor-made for rolling courses where you need lightness for the climbs balanced with aerodynamics for higher speeds on the flats. The semi-aero aluminum rims are milled between the spoke holes to keep the weight down while the bladed spokes slice through the wind. Plus, these speedy hoops boast Campy's legendarily smooth bearings for a fast, frictionless ride.
