Carbon Rims Quality Control and Testing
Carbon rims must be stable in strength, shape, spoke hole structure, tire fit, and long-term riding performance. At Carbon World, quality control starts from material inspection and continues through production sampling, performance testing, report recording, and final review before shipment. This process helps us provide more reliable carbon rims for road, gravel, MTB, BMX, and custom OEM wheel projects.
Carbon Rim and Wheel Quality Check
1. After production, Carbon World checks key rim dimensions and assembly performance.
2. Inspection includes roundness, lateral stiffness, tire pressure resistance, parallelism, rim wall height, and wheel hub fatigue performance.
3. Roundness and parallelism checks help maintain rim shape and riding stability.
4. Tire pressure testing verifies tire fit, bead seat safety, and rim stability.
5. Rim wall height inspection helps ensure consistent tire seating and dimensional accuracy.
6. Wheel hub fatigue testing evaluates durability under repeated loading.

Carbon Rim and Wheels Quality Testing
Carbon World uses strength and durability testing to assess how carbon rims perform under real-world riding conditions.
UCI Impact Test
The UCI impact test helps evaluate rim safety under sudden impact.
Rim Spoke Tension Test
The rim positive rigidity test checks how the rim responds to vertical loading.
Walk Fatigue Test
The spoke tension test focuses on the spoke hole area during wheel building and riding.
Rim Positive Rigidity Test
The fatigue test simulates repeated loading over time to review long-term structural stability.

Carbon Rim and Wheels Test Report Records
Carbon World uses strength and durability testing to assess how carbon rims perform under real-world riding conditions.
Carbon World keeps test reports for key carbon rim quality tests during product validation and production sampling. These reports record test conditions, data, photos, and final results for each rim model.
The reports help us track product quality, review production consistency, and confirm that rims meet our internal standards before shipment. For OEM and ODM projects, they also provide customers with clear testing records and quality evidence before bulk orders are delivered.

Rim Spoke Test Report
| Test Report | Test Conditions | Judgment Criteria | Test Result |
| UCI Impact Test Report | Mount the wheels (without tires) onto the testing machine. Align the impact point at a 90° angle relative to the valve hole. The impact hammer weighs 9.52 kg, and the drop height is 86 cm. Subject the rim to a vertical free-fall impact test at a position between the spoke holes. | According to the factory certification standard. | The rim sample passed the impact test. |
| Rim Positive Rigidity Test Report | Test speed: 40 km/h. Load: 64 kg. Four jump blocks are used, with each block measuring 10 mm × 50 mm. Swing angle: 5°. Tire pressure is set at 90% of the maximum tire pressure. | According to the factory certification standard. | After fatigue testing, no abnormality was found in the rim structure, bead area, or tire mounting area. |
| Walk Fatigue Test Report | The wheel is fixed on the machine. Downward forces are applied at 10 kg, 20 kg, and 30 kg. The corresponding deformation is recorded to calculate rigidity. | Used for data collection and rigidity review. | Deformation values were 0.52 mm, 0.99 mm, and 1.43 mm. The average rigidity value was 197.3 N/mm. |
| Rim Spoke Test Report | Machine rising speed: 10 mm/min. Rim spoke tension value: ≥350 kgf. Six spoke holes were tested. | According to the factory certification standard. | No abnormality was found at 350 kgf spoke tension. The recorded damage values ranged from 499 kgf to 613 kgf. |
