Secondary retention devices fall into two basic categories:
1. The clip-on type is a part which the manufacturer adds to the front wheel hub or front fork.

secure the wheel can cause the wheel to wobble or disengage, which could cause you to lose control and
fall, resulting in serious injury or death.
