5 Speed Shifter Conversion Parts

The parts in this package will allow you to convert a Brompton (post-2017) right hand integrated shifter from 3 to 5 speed, for use with BrommiePlus 5 speed chain pusher or Brompton Advance Rear Derailleur (on the P/T line bikes). Please note that this shifter is not suitable for the aftermarket rear derailleurs. We will release a version suitable for those aftermarket derailleurs at a later date.

This shifter internal is specifically designed to work with BrommiePlus 5 speed chain pusher for use with 1.65mm sprockets and 2.15mm spacers (road bike 11 speed specification). The shifter is also compatible with Brompton Advance Rear Derailleur when using road 11 speed sprocket and spacers.

The key internal parts are made by CNC machining from aluminum alloy for precision and durabiltiy.
