3-SPEED GEAR SHIFTER
3-speed shifters are used on 3 and 6-speed bikes
If you are unsure about any fitting or operation instructions please contact a Brompton dealer
USING THE SHIFTER
The 3-speed shifter uses a self-returning lever to change between the three gears. Pushing it down with your
thumb will shift into an easier gear and flicking the lever upwards with the back of the thumb will shift into a
harder gear (fig. 11). It is important to stop pedalling or back pedal slightly when changing gear, if you do
not do this it is possible to damage the hub internals. The indicator window (fig. 11, 12) shows you which
gear is selected.

FITTING THE SHIFTER
The shifter mounts to the right hand brake lever, it is held
in place by two M3 screws, these should be tightened
to
0.35Nm
. Do not overtighten the screws as this can
reduce the performance of the shifter and damage the
parts.
As standard a spacer (fig. 13) is fitted between the
shifter and brake lever. This spacer is vital to ensure
clearance between the shift lever and the grip.
On P-Type bikes and also on M, H & S-type bikes using
non-standard grips, the locking collar or grip material
can interfere with the lever operation, if the spacer is not
fitted.
