ability to select the ideal gear for any situation. The NuVinci
hub also boasts a wider range than many traditional shift
systems.
NB
Are you noticing that you are having to pedal harder in
the lowest gear and/or too easily in the highest gear? This
means your range has narrowed
(see table 3, chapter 21) ;
in this case the gears will need to be adjusted using the
adjusting screw. The best thing for this is to take it to your
specialist, since this is a painstaking task.
If your NuVinci Harmony has been re-installed, or if the
system is working inconsistently or even incorrectly, you
will need to calibrate the system. To do this, switch the
system on first. Ride the bike gently throughout the entire
calibration procedure.
To start the calibration program, press the “mode” button
(fig. 62, A) on the Harmony H8 controller and hold it down
until the rear hub starts to shift (usually 5-7 seconds) . After
that release the button. Keep on pedalling gently while
the system shifts several times from “low” to “high” and
completes the calibration process.
N.B.: the Harmony manual cannot be calibrated.
Sturmey-Archer
If your bike has a Sturmey-Archer internal hub gear, set the
shifter
(fig. 64) to the middle gear. Next, turn the pedals a
few times so you can be sure that the hub itself is also in
the middle gear. Now unscrew the nut
(A) , and twist the
sleeve (see fig. 65) . The end flat of the control rod (B) must
be flush with the end of the axle. You can see it through
the opening in the axle nut. Next, tighten nut
(A) again. You
can check whether the adjustment is correct by shifting a
couple of times, and looking to see if the setting returns to
the initial position. If everything is in order, you can clip the
rear section of the chain case back on.
