<p>A bearing which introduces a delay into the lock up path of a reverse activated activator, typically the delay is half a revolution, such that any unintentional minor reversal from the freewheel direction can be tolerated without triggering an unwanted response, the bearing is particularly useful to delay the action of a reverse stimulated rotational activity such as the activation of a brake or a bicycle stabilizer. Improved bearings and bushes useful in this application are also provided.</p> |
