It's finally here: The first aero-gravel wheelset from the EVO WASO line, optimized for maximum performance. It offers the usual brilliant aerodynamics with minimal crosswind susceptibility and maximum agility on and off the road.
In terms of aerodynamics and acceleration, even with this wheelset, we are once again the benchmark in the aero-gravel wheel category, according to the comparison test in RennRad Magazine 08/24.

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 consider the combination of tire, rim, and setup (reduced maximum pressures, especially for tubeless and hookless setups). If the wheel and tire have different maximum values, the lower value always applies as the valid maximum. Excessive pressure can cause tire blowouts, leading directly to crashes and severe injuries.
Use only tire types and sizes approved in the spec 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 assembly, disassembly, and maintenance of safety-critical components (e.g., spokes, hub bearings, tubeless setup, brake rotors, thru-axles, cassette) must only be performed by qualified specialist personnel. Improper execution can lead to material failure and serious accidents.
Always tighten thru-axles, cassettes, and brake rotors with a torque wrench, observing the torque values specified by the respective manufacturer. Grease the freehub body before installing the cassette to prevent cogging of the sprockets. When mounting or dismounting tires, use only plastic tire levers as a last resort; never use metal levers or other hard objects to avoid damage to the rim and tire.
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 UNBEATABLE PRICE-TO-PERFORMANCE RATIO
Weight,aerodynamics,stiffness:optimized. The wheels in the Leeze WASO line are optimized through D2R Development to deliver top performance in every riding and racing scenario.
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.
