THE SHIFTING PRINCIPLE
● Briefly pressing one of the two shift levers immediately
triggers the gear shift.
● Pressing several times in succession triggers the change
of several gears in a row.
● The gear shift is carried out when the cranks reach the
vertical position in the pedalling motion.
This targeted shifting in the not so heavily loaded crank
positions is only activated above a certain pedalling
frequency.
● At lower pedalling frequencies, the system shifts
immediately.
SHIFTING UNDER LOAD
The system is designed to shift in any situation. When shifting
under load, for example when going uphill, riding with a higher
pedalling frequency is advantageous.
● The system shifts with a high pedalling frequency with the
crank in a vertical position. The faster the cranks circulate,
the sooner the gear shift is performed.
● Shifting under load may be associated with a popping
noise. This is not a cause for concern. The system is
designed for shifting under full load and is not damaged.
● In certain situations, a gear shift may be cancelled due to
excessive load (e.g. high pedal load when stationary) to
protect the system from damage. The system will attempt
to change gear for 2 seconds. While this is happening,
noises from the shift motor can be heard. If sufficient relief
is provided within this phase, the gear change is carried
out successfully.
● Due to the system, there is an idle travel of a few degrees
after the gear shift in which the cranks offer no resistance.
This is not noticeable during normal riding. When shifting
under high load, this effect is slightly noticeable.
