Gears
Shimano Nexus 8 with 8 gears
The Shimano Nexus 8 is a hub gear with 8 gears.
Shifting is easily done by turning the grip shifter at the
grip on the right side. You can always shift, even in
stand. In the display of the grip shifter you can see the
current gear.
*
Attention!
Decrease the force on the pedals while
shifting for smooth shifting and a pro-longed lifetime of
the hub.
Fine tuning Shimano Nexus 8
To fine-tune the hub gears you can put it in 4th gear.
Turn the pedals backwards a few times. Check if the 2
yellow indicator bars at the bottom of the rear cassette
are aligned.
Adjust the cable tension by turning the cable
adjustment screw attached to the grip shifter until the
desired result is achieved.
NuVinci N330-N380 stepless shifting hubs
The NuVinci N330 and N380 are maintance free hub
gears that shift stepless from the lowest to the highest
gear. The NuVinci N330 and N380 hubs are known
for their impressive gear ratios of 330% and 380%
respectively.
Controlling it is easily done by turning the gripshifter
at the grip on the rightside. You can always shift, even
while standing still. However, if the bike is in motion
during shifting it will feel a bit easier, and you can shift
between the entire gear range only if the wheels are
turning. In the display of the grip shifter you can see
the current gear ratio. The N380 has a surprising display
with a small cyclist that seems to move either over a hill
(low gear) or move over a flat surface (high gear).
