Operation Manual

CyclePinion gearbox

WARNING

Chain or belt motion while the crank is stationary.

Risk of accident and injury!

x Before every ride, make sure that the sprockets and rear

wheel hub can freewheel smoothly.

x Turn the crank backwards. The chain must not revolve when

the sprockets and rear wheel hub are freewheeling.

x Stop if damage occurs to the Pinion gearbox or unusual

noises are produced.

8.2 Shifting gears with a Pinion gearbox

Note that the shifting behaviour of a Pinion gearbox, both with a chain and

with a belt drive, is different to that of a derailleur shifting system. Keep off

the road while you familiarise yourself with the Pinion gearbox and the

change in shifting behaviour.

The marking (“>>”) on the fixed part of the twist-grip control shows the selected gear,

for example between 01 and 18.

x To shift into a higher or lower gear, first move the twist-grip control slightly in the

direction you want to shift, then quickly shift in the desired direction.

– It is possible to shift through multiple gears at once, such as from 02 to 06.

– Gears can be shifted while at a standstill and while the crank is stationary or turning

backwards.

– There is limited potential for shifting down under load, for example from 18 to 17.

– To protect the Pinion gearbox, gears are not shifted when the pressure on the

crank or pedal is too strong, such as when riding out of the saddle.

x Only shift down when there is not a heavy load on the crank or pedal.

– There is potential for shifting up under load, for example from 02 to 03.

– Exceptions to this are gear changes from 06 to 07 and from 12 to 13, as the

gearbox needs to double-shift for these gear changes.

x Only shift from 06 to 07 or from 12 to 13 when there is not a heavy load on the

crank or pedal.

– It is not possible to shift directly from the lowest gear to the highest or from the

highest gear to the lowest.
