Brompton P Line Advance 4 Speed Shifter & Brake Lever - Black

Genuine replacement 4-speed shifter and integrated brake lever for P Line bikes.

The gear shifter uses a self-returning mechanism to change between the four gears, pushing down changes to an easier gear, and up to a harder gear.

Note - this shifter is not compatible with pre-2017 M/H handle bars and is only compatible with the 4-gear mechanism.
