Take on the course profile.
The CC 45 PRO R is your race upgrade for attacks, pace changes, and undulating race courses. Designed for pure agility at race speed—when every second counts and explosive power is key. Experience the perfect balance of aerodynamics and weight.With its 45 mm D2R Aero carbon rim, the CC 45 PRO R combines low weight with high lateral stiffness. This makes the wheelset the perfect choice for anyone seeking high aerodynamic performance on hilly to mountainous terrain. It responds instantly to every pedal stroke and remains precisely controllable even in hectic race situations. Tracking stability, crosswind stability, and razor-sharp handling are the result of a development process consistently focused on race performance.
Technically, the CC 45 PRO R features a 23 mm hooked rim profile with a 31 mm outer width—optimally designed for modern road tires 28 mm and wider. 18 SAPIM CX carbon spokes reduce rotating mass and noticeably increase stiffness. Combined with the new Leeze PRO hub, the result is an uncompromising race wheelset with a total weight of just 1,160 grams.
- Optimal aero performance setup with 28 mm / 30 mm tires
- Best performance-comfort setup with 32 mm tires
- Tire widths from 28 to 45 mm can be used

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.
Only use tire types and sizes approved in the datasheet (especially for tubeless and hookless setups). Incorrect combinations can lead to tire defects or tire blow-off, directly causing crashes and severe 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.
