Brompton chain pusher assembly 

This is the Brompton derailleur mechanism which pushes the chain tensioner wheels between the two rear sprockets on a two speed or six speed Brompton - it works in conjunction with the DR style chain tensioner (QCTADR)

Complete with wing plate 

The chain tensioner has not changed from the pre-2017 to the 2017 onwards integrated shifter derailleur - so is compatible with all year Bromptons (as long as it has the hexagonal braise on the rear triangle for connecting the wing plate)

Brompton 2020 Q part code: Q101186
Brompton Q part code: QCHPUA
Brompton part number: 9012169 

Note: there is a 'crack' in the wing plate to allow expansion of due to the paint on the Brompton frame

We made this short video on how the Brompton derailleur works
