Wheels

Performance Upgrade Made Easy The C38 brings carbon fiber high performance to the real world. It's a versatile all-rounder equally at home crushing gravel washboards and summiting alpine passes. Optimized for use with modern wide tires, providing the right amount of sidewall support to facilitate surefooted handling in all conditions, the C38 wheelset is a great handling, lively climbing, robust all-road performer that also aerodynamically outperforms many deeper, aero-specific rims that cost twice as much. Carbon wheels are a true performance upgrade to any bike, but too often the price tag puts them out of reach. The Rapide C38 shatters that barrier and brings a class-leading Roval carbon rim and DT Swiss reliability together to provide riders with the best performance carbon wheel per dollar.

Zipp's 353 NSW Tubeless Disc-brake wheel is the pinnacle of our pursuit of versatility and speed. This wheel fuses Zipp's two most advanced approaches, Sawtooth rim profile and TSE, for an all-encompassing approach to performance. With its undulating 45mm-deep rim shape, the 353 NSW provides speed on every terrain with best-in-class aerodynamic efficiency and crosswind stability. The 353 NSW is Zipp's lightest tubeless wheel yet, making it a fast-puncher ready to fight its way into the breakaway. Zipp's use of hookless (straight side) rims in the 353 NSW is integral to achieving our mission of Making You Faster. With hookless, the transition between the tire and the rim is more seamless and aero. Zipp's hookless rims have more efficient resin distribution, which means lighter wheels. They also are highly durable. Zipp's 353 NSW's Sawtooth rim shape with Hyperfoils optimizes aerodynamic efficiency and crosswind stability. The Sawtooth design also allows the rim to be structurally strong but light. That will help you snap out of corners and maintain that speed no matter the terrain, especially in the steep, punchy stuff. The 353 NSW utilizes Zipp's Total System Efficiency, or TSE, approach to wheel design: overcoming specific barriers to speed: wind resistance, gravity, rolling resistance, and vibration losses. The wheel's 25mm internal width is ideal for running wider tubeless tires at reduced air pressure for a more efficient ride. At the center of the 353 NSW is the Cognition V2 Hubset, re-engineered with an updated Axial Clutch V2 mechanism for quicker engagement and lower friction, as well as improved durability. - Versatile endurance wheel for the modern road bike with tubeless and hookless rim profile - Our lightest tubeless wheel yet, making it a fast-puncher ready to fight - Optimized tire bed for easy tire installation - TSE for greater efficiency and reduced rolling resistance - Sawtooth rim with Hyperfoil nodes and HexFin ABLC dimple pattern for top aero and crosswind-stable performance with an undulating rim depth - Cognition V2 hubset rolls efficiently whether you are pedaling or coasting.

From the purist gravel racer to the mixed-surface fanatic, Terra CLX II provides a level of weight savings and material confidence that’s unheard of in the all-road or gravel space. This tier of weight-savings translates to rocket-like acceleration off the starting line, nimble performance in the hills, and unleashed efficiency on those loaded-down long-haul excursions. Weighing in at just 1250 grams, the Roval Terra CLX II are the lightest wheels in their class, rivaling pure climbing wheels in terms of weight and out-performing in raw toughness. We were able to get even lighter than before (50 grams lighter) by utilizing Low Flange Disc (LFD) hubs, borrowed from the Alpinist CLX II wheels. What’s being carried forward from the previous generation, is the rim. With its multiple Unbound victories, we we kept what was already class leading, and extended our lead. Because Terra CLX II is a hooked rim, you’re able to ride almost any tire and pressure. Thanks to the 25mm internal width, they work seamlessly with 28-47c tires (up to 80 PSI), giving you options to customize your setup for what’s ahead. Using Roval LFD hubs, still spinning on DT Swiss 180 hub internals, Terra CLX II continues to provide flawless ride quality. The CINC ceramic bearings inside do some serious heavy lifting when it comes to the efficiency of these wheels. Even with laundry list of demands that need to be met for the serious gravel racer, to the all-road explorer—the Roval Terra CLX II checks every box with authority. - Rim: Terra CLX Carbon Clincher, 700c, Disc Brake, Tubeless Compatible - Rim Details: 32mm Depth, 30mm External Width, 25mm Internal Width - ERD 577mm - Hub: Roval Light Hub (LF13/LF14R) Center Lock, DT Swiss 180 Ratchet EXP 36t internals (10 degs), 100x12mm & 142x12mm, Shim.

Zipp's 3ZERO MOTO carbon 29 enduro/trail wheelset is inspired by moto to provide riders with the control and durability required for pure trail speed. This wheel and its MOTO Technology have already been proven by multiple victories in the Enduro World Series with our pioneering partnership with the Lapierre Zipp Collective. While other wheel brands limit their focus to traditional box-section rim designs, Zipp engineers—uninhibited by legacy technology—took a different approach. They looked to motorsports as a model. Zipp's Moto Technology's single-wall rim is the optimal approach for an enduro/trail wheelset. The resulting rim provides something we call "ankle compliance." Imagine a runner rounding a sharp turn, the ankle naturally flexing to maintain grip as the runner leans. The 3ZERO rim can locally flex to stay parallel to the ground during cornering, increasing traction like a human ankle adjusts while running. This ability to twist locally allows it to deflect during single bead impacts without the rider getting bounced offline. 3ZERO MOTO helps you take the most direct route, saving seconds when and where they count most. At the center of the 3ZERO MOTO is the ZM2 hubset. This German-engineered hubset features 12 pawls and 132 points of engagement for a quicker response. The hub's improved seal design means better durability on rough terrain. Quarq's TireWiz is an add-on option for 3ZERO to dial in your pressure for an even more compliant ride. - Higher impact resistance - Reduced chance of pinch flatting - More traction in rough corners - Smoother ride in rocky terrain - Ability to run lower tire pressure - Reduced rider fatigue - Frustration-free tire installation - Rim is designed for compliance, creating the feel of extra suspension - German-engineered hubset features 12 pawls and 132 points of engagement for quicker response and also has improved durability - Lifetime Warranty

CZR i30 wheels were designed to handle it all, which is why they feature a strategically reinforced carbon layup and are hand built using double-butted spokes, brass nipples and high-engagement hubs featuring top-tier bearings and oversized freehub seals to establish themselves as wheels that simply won't quit. Solid Strip & TCS Tape - Durable nylon strip that lies between the rim and tubeless tape to prevent tubeless tape from pushing into the spoke holes and ensures a smooth interface between the tire and rim. The smooth surface makes it easier to mount a tire by preventing air from escaping around the bead at each indent during inflation. Solid Strip also protects the airtight system from puncture in the case of a broken spoke. 3-Cross Lacing & Brass Nipples - Too many companies are trying to save weight by offering "enduro" wheels with 2-cross lacing patterns and inadequate alloy nipples. While those are suitable for XC and light trail usage, there's no replacement for the long-term reliability of a 3-cross lacing pattern with brass nipples holding it all together. Frequency Hub - The world's best carbon rims deserved to be paired with high-quality hubs that further improve the performance of a lightweight, dependable carbon wheelset. Frequency hubs feature a low-drag, 6-pawl design that alternates contact between two sets of 3-pawl groupings to provide a responsive 5 degrees of freehub engagement. Heavy-Duty Pawl Springs - CZR i30 wheels feature heavy-duty pawl springs that engage with greater force to counteract the additional torque caused by sudden cranking on steep trails. We also offer a Light Pawl-Spring Kit that can be purchased separately for CZR i30 riders who prefer a quieter hub with lighter pawl engagement. Usage: Trail, Enduro
