The CH 40 BASIC AR is designed for those who don't want to choose between road and gravel. On varied terrain, this wheelset showcases its strengths: high stability, precise handling, and noticeable control.
The lower rim profile and robust carbon layup make this wheelset the ideal companion for those who demand uncompromising durability and agility, and seek performance off-road.
The 40 mm rim depth and 25 mm hookless inner rim width ensure high agility and a perfect tire fit for wide allroad tires. Built with the new Leeze BASIC hubs and 24 two-cross SAPIM Straight Pull bladed spokes, the CH 40 BASIC GX is extremely robust, yet light and agile at only 1370 grams.
- Best allroad-comfort setup with 32-35 mm wide tires
- Best gravel performance setup with 40-50 mm wide tires
- Tire widths from 30-65 mm usable
(Hookless compatibility required from tire manufacturer! Maximum pressure 4.5 bar – may need to be further reduced depending on the mounted tire!)
Note on Product Designation: Due to product updates, the abbreviation GX may still appear on some CH 40 BASIC AR wheelsets. This still refers to the CH 40 BASIC AR with 25 mm hookless inner rim width. The new CH 40 BASIC GX with 28 mm hookless inner rim width is a standalone model and available separately – you can find it here.

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 with serious injuries.
Use only tire types and sizes approved in the technical specifications (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. Only use the wheelset 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.
