P Line Wheel Nut Corrective Action


Why do I need to change the nut?

During our quality control we identified that the old design of the front wheel nut does not run all the way to the top of the part which in certain circumstances the front wheel skewer nut thread can become partially or full stripped.

For these reason, we decided to redesign the nut and replace it on all the P line bikes affected.  


How can I know if my bike is affected?

If the serial number of your Brompton P Line is lower than 2203113405, your bike may be affected. A further visual check can be carried out without removing the front wheel nut, please check out the video below:
