Seventeen different bike brands have been affected by the issue and have announced a joint recall of over 1.5 million bikes. The issue is said to only affect disc brake bikes equipped with quick release skewers, the lever of which can then enter the disc brake rotor.

A signpost website – www.quickreleaserecall.com has been set up and provides full details of the issue which is said to affect internal cam quick release levers. When fully open an internal cam lever can rotate far enough to enter the disc rotor. Should this happen while riding, it has the potential to cause the front wheel to lock, and cause serious accident. However, there is no issue if the quick release is closed correctly.

There is video that provides information on the issue:

The website suggests you use a pencil to check that you have the necessary 6mm clearance. When the quick release is fully open and rotated towards the disc, the pencil should be able to fit between the two (see the picture below).

If the lever can get any closer, then you need to replace your quick release with an external cam skewer, which will not be able to rotate as far when open. The brands listed below will be replacing quick release skewers free of charge, although it is not yet clear if this is worldwide or just for bikes affected in the US.
