Gear Shifter with integrated brake lever

Gear Shifter with integrated brake lever LHS - 2 speed

Brompton 2017 derailleur gear shifter with integrated brake lever
2 speed shifters are used on 2 speed and 6 speed bikes and control the rear derailleur gear
These new shifters were introduced on 2017 model bikes late in 2016
The shifter is not compatible with older brake levers 
The Brompton 2-speed shifter uses a self-returning lever to change between the two gears.
Pushing it down with your thumb will shift into an easier gear and clicking the lever upwards with the back of the thumb will shift into a harder gear.
It is possible to change gear while pedalling or stationary, though the gear will not engage until the pedals are moving forward (i.e. you start pedalling).
The indicator window shows you which gear is selected.
