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)
