Brompton replacement chainwheel guard disc for "spider" 50T ring

Replacement Brompton Spider 50T chain guard

The Brompton "spider" crankset was introduced in January 2013 - this is the guard disc (to stop you getting grease on your trousers) which is part of that crank set.

The guard has the size embossed into it - allowing you to choose the correct one (if you still have the original) without counting the number of teeth on the chain ring

Note: This is not compatible with the older fixed chainset which was discontinued in 2016

It is held in place with 5 self tapping screws (included)
