Brompton Chain Pusher 2/6-speed

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.

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).

Complete with wing plate.
