Type MH 3115 with coaster brake
Type MH 3105 without brake

SPECIFICATION
The ideal drive for city and recrea-
tional bikes – simple to operate
and adjust with precise gear sel-
ection using a variety of shifters.
The Spectro T3-hub is practically
maintenance-free.
Advice:
The hub is not suitable
for tandem use.
GEAR CHANGING
• Keep pedaling without effort as
you change gears.
• Should the desired gear not
engage immediately, stop peda-
ling for a short moment.
• Change gears in time before
going uphill.
BRAKING
• When riding down a long and
steep slope it is absolutely
necessary to apply also the
second brake (front wheel
brake) alternately, to allow the
coaster brake to cool down.
Type MH 3115
• Heating the coaster brake too
severely can lead to loss of
lubricant, causing too sharp a
braking action.
Type MH 3125
• The drum brake can be control-
led very precisely and provides
very effective braking decelera-
tion compared with conventional
bicycles brakes. However the
drum brake only reaches maxi-
mum braking power after a cer-
tain breaking in period
• To get used to the new brake,
operate the brake lever carefully
to acquire a feel for the drum
brake's deceleration.
• Do not rinse hub with benzine,
petroleum etc. as this could
produce impurities in the brake-
pads.
Caution!
• The brake anchor plate must be
replaced if oil or other sub-
stances containing grease get
into the brake pads. Oily brake
pads reduce braking effect and
cause the brake to fail comple-
tely. This may result in acci-
dents with extremely serious
injuries.
• If the bicycle is left standing for
long periods, surface rust in the
brake drum may increase bra-
king effect. For this reason, start
by braking gently a few times
the next time the bicycle is
used to remove the surface rust.
This will prevent the brake from
locking suddenly.
• Do not touch hub after
cycling - risc of burning.
