Adjust the quick-release mechanism so that the quick release and the rear stop are correctly placed on the holding force test tool (called Xielu A). At 5mm from the end of the lever, add a force of 200N to the chain to eliminate the locking force. Apply a force of 500N and 178CN to the front and rear axles in the direction of wheel removal. Observe for displacement for 30s. See Figure 5 for examples. 5.12 Quick release mechanism test
Install the quick release front and rear axles on the test tool, apply a force of 250N at 5mm from the end of the lever, and observe the damage of the tension mechanism.
The quick release mechanism should be adjusted to prevent the mechanism from being completely locked under this force. 5.13 Quick release mechanism self-locking force test
According to 5.11, the lock is turned on, and a force of 5CN is applied at 5mm from the end of the lever in the loosening direction. The lever shall not rotate. 43
