The Roval CLX 32 Disc full-carbon clincher is the perfect performance disc wheel; light, stiff, and fast. The wide internal rim width provides an optimum tire profile for precise handling, stiffness, and aerodynamics. The Center Lock hub makes this an ideal wheel for the muddiest cross-race or fast paced ride. This wheel offers a non-SCS rear hub for traditional QR or 12mm thru-axle compatibility.

When we set out to create a wheelset built purely for speed, we wanted to make it more than just fast. Not that being fast wasn't a priority, but we were tired of wheels that only performed well in a straight line. In the end, we developed the CLX 64, the fastest wheel that we've ever tested. Not only is it the fastest in the tunnel, but its prestige has been verified with Gold Medals in the men's road race, time trial, and team time trial at the 2016 UCI World Championships. 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 simply 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 studying tire and frame interactions in the Win Tunnel, 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. The rim is not the only component of the CLX 64 that contributes to its aero prowess though, in order to create the fastest wheels, we focused on the wheels as a system, not just a rim with "other parts," and our Aero Flange (AF) hubs play a significant role. Designed completely in the Win Tunnel, our AF hubs feature an incredibly small frontal aero, without sacrificing stiffness, making them aerodynamically efficient. Taking the advantage a step further, these wheels were developed to work in harmony with modern-width 24C tires. The 21mm internal rim width spreads the tire out, in this case to 26C, making it seamlessly meet the rim. Not only does this create a system with low aerodynamic drag, but one that has exceptionally low rolling resistance and inspiring grip in the corners. And to make sure we checked all of the feature boxes, we also made the rim tubeless-ready. To top off the multitude of performance features of the rim, we chose the highest quality build components to pair the CLX 64 front with. Starting with DT Swiss Aerolite bladed spokes, which test faster than their round counterparts in the Win Tunnel, we hand-laced the 64 rim to our AF hubs that house CeramicSpeed's legendary bearings. Why hand-built? Machines make mistakes and mistakes aren't something we're ok with, so we have real people lace each wheel by hand. - 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 - Front Hub: Roval AF1, CeramicSpeed bearings - Nipple Type: DT Swiss Pro Lock hexagonal - Rim Depth: 64mm - Rim Material: Carbon - Rim Type: Carbon clincher, 2Bliss Ready - Rim Width: 20.7mm internal, 29.9mm external - Spoke Count: 16 - Spoke Pattern: Radial - Spoke Type: DT Swiss Aerolite T-head - Weight: 695g

The 1Zero HiTop S wheelset melds high value with high performance for a better and faster ride. Trail compliance is vital, with modern cross-country courses becoming rougher and more challenging. No longer is it good enough for an XC wheelset to be stiff above all else. Instead, a wheelset should feel alive. The 1Zero HiTop S carbon rim complies with the terrain thanks to Zipp’s proprietary HITOP Technology for carbon layup. The result is a light XC race or adventure wheel that carries speed through all sections of the trail, rocks, roots, and ruts with the durability required for a trail bike with up to 130mm of travel. A compliant wheel provides more confidence. The 1Zero HiTop S features the dependable ZM 900 hubset. - Carbon – 24H Hookless rim, compatible with Tube-type or Tubeless tires - HITOP Technology produces proprietary rim layup to provide compliance and confidence when the trail gets rough - Low weight for effortless accelerations and climbing - Winged rim provides a smooth resting surface for the tire, reducing the chance of pinch flats after a rock hit - Sapim CX Sprint spokes laced to the ZM 900 SL hub with standard or Torque Cap options - Lifetime Warranty - Compatible with TyreWiz tire pressure monitoring system, sold separately

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
