The CC 38 Road EVO WASO stands out for more than just its light weight. Especially in the mountains, on winding courses, or in criteriums with frequent accelerations, the CC 38 Road EVO WASO will have you flying down the course. Despite its relatively flat carbon rim, the wheelset boasts exceptional aerodynamic performance. Compared to a conventional aluminum wheelset, this already results in significant power savings. The brake track features a laser-etched pattern that is perfectly matched to our Ultra Grip Carbon brake pads. This ensures optimal braking performance, even in wet conditions.

Here you'll find detailed instructions on how to use and maintain your wheelset:
Please observe the following safety instructions to ensure your safety and the longevity of your wheels. The accompanying or online user manual is an integral part of the product and must be read in its entirety before use.
Do not exceed the specified maximum total weight (rider + bicycle + luggage). Exceeding this limit can lead to equipment failure and cause a fall resulting in serious injury.
Do not exceed the specified maximum tire pressure. Always take into account the combination of tire, rim, and setup (reduced maximum pressures, especially for tubeless and hookless setups)! If different values apply to the wheel and tire, the lower value is always the valid maximum. Excessive pressure can cause a tire blowout and thus lead directly to crashes resulting in serious injuries.
Use only tire types and sizes approved in the technical data sheet (especially for tubeless and hookless setups). Incorrect combinations can lead to tire failure or the tire coming off the rim, which can directly cause crashes resulting in serious injuries.
The installation, removal, and maintenance of safety-relevant components (e.g., spokes, hub bearings, tubeless setup, quick releases, cassette, brakes) must only be performed by qualified specialist personnel. Improper execution can lead to material failure and serious accidents.
Always tighten the cassette with a torque wrench and observe the torque values specified by the respective manufacturer. Grease the freehub body before installing the cassette to prevent the sprockets from digging in. Use only brake pads approved for the respective rim material and align them so that they fully contact the braking surface without touching the tire or rim edge. Always keep braking surfaces clean and replace worn pads promptly.
When mounting or dismounting tires, use only plastic tire levers as a last resort, never metal levers or other hard objects, to avoid damage to the rim and tire.
For quick releases, ensure correct tension and secure closure with noticeable resistance. Align the lever so that it cannot be opened unintentionally, and check for a secure fit before every ride.
Only use the wheelset for its intended purposes (e.g., road bike or gravel), see link: Leeze Application Areas. Use the wheelset only with disc brakes. Do not expose the wheels to high temperatures (e.g., in a car in the sun or leaning against a radiator). Not suitable for downhill, BMX, jumps, cargo transport, or other extreme forms of use.
Regularly check your wheels for cracks, delamination, and damage to spoke holes, brake track, or rim bed. For optimal spoke tension and trueness, we recommend wheel checks every 5,000–10,000 km, every 12–24 months, or after 6 months of inactivity. If damage is suspected, stop riding immediately and contact Leeze service. In case of doubt, discontinue use immediately and consult the manufacturer or a specialist dealer.
Clean rims, spokes, and hubs regularly with mild soap and water; avoid high-pressure cleaners and direct water jets on bearings. Store wheels dry and dry them after wet rides. For extended periods of inactivity (>6 months), we recommend a bearing and wheel check. Clean and grease the freehub system regularly. For tubeless systems, replace sealant and rim tape at least twice a year to prevent damage to spoke nipples. Negligence in maintenance can lead to premature wear, malfunctions, or sudden failure during a ride, thus posing a safety risk.
Stop riding immediately and have the wheels professionally inspected, even for minor or invisible damage. Invisible cracks in the carbon can lead to sudden breakage and a crash.
D2R perfected – The unmatched price-to-aerodynamics ratio
D2R Aero Development: With the WASO line, we are fully leveraging the capabilities of the Leeze D2R Development team led by Prof. Dr. Eric Helter. We have run various high-performance computers for hundreds of hours to ensure that every wheelset is maximally optimized for its intended use in terms of aerodynamics. We now also utilize VR-based wind tunnel simulations and AI for this purpose, thereby ensuring the highest WASO standards in future generations of wheels as well.
d2r Development
Optimized wheel weight: Thanks to extremely lightweight components that are perfectly matched to one another, we achieve record-breaking weights. We also continue to rely on the proven, stiffness-enhancing combination of Sapim CX-Ray spokes and the slightly thicker CX-Sprint knife-blade spokes for the drive side of the rear wheel.
Leeze Labs
Maximum stiffness: Through extensive FEM analyses, we have achieved exceptionally high stiffness in our wheels despite their extremely low weight. Not only were the fiber orientation, fiber volume fraction (ratio of fibers to resin), and fiber count precisely determined in advance, but they were also accurately implemented using an innovative braiding process.
