Introduction
Congratulations on your purchase of the NuVinci Continuously Variable Planetary
(CVP) and CruiseController. The NuVinci CVP is a revolutionary bicycle drivetrain that
will deliver the quietest, smoothest ride ever; completely eliminating the jerkiness
of missed shifts, dropped gears and gear lash. A simple twist of the CruiseController
seamlessly adjusts the gear ratio to easily adapt to the terrain and your personal
riding style. Thank you for joining the NuVinci Smooth Revolution… relax and
enjoy the ride!
This manual contains important information about the installation and use
of the NuVinci CVP and CruiseController. Please take time to carefully read
these instructions.
Please note the following:
• The illustrations in this document show a Model N171B but apply to Model
170S as well. While there are some internal differences, the visible differences
are in the hub shell and the 170S weighs slightly more. A data sheet for the
N170S is available at www.fallbrooktech.com.
• The NuVinci CVP (Models N170S and N171B) was designed for normal use as
a rear wheel hub in most bicycle applications by riders of all proficiency levels.
The hub is not approved for any application in which input torque to the hub
exceeds 130Nm (96 lb-ft) or extreme applications, such as freeride or downhill
use, where excessive forces can be expected to cause damage to rear wheel
components like the rims, spokes or the hub.
• The NuVinci CVP is designed for use in both horizontal and vertical dropouts.
It is only permitted to use the NuVinci drivetrain in vertical dropouts if
assembled with our specifically designed parts. A Vertical Dropout Kit
(PN: N171B-VDO-001) is available from Fallbrook Technologies.
• Installation and repairs must be made by a qualified bicycle specialist.
• This manual assumes a level of knowledge and skill consistent with that of an
experienced bicycle assembler or bicycle mechanic.
• If you have any questions about the NuVinci CVP or CruiseController,
please contact our customer service department at +1 888.NuVinci

Controlling the ratio of the
NuVinci CVP
Controlling the ratio of a drivetrain
equipped with a NuVinci CVP is simply
a matter of moving the CruiseController
to the indicated position for the desired
ratio. Since there are no fixed gears,
the desired ratio is determined by your
comfort level. Ratio changes can be
made while pedaling, coasting; even
while stopped.
Which ratio should I be in?
The lowest ratio on a NuVinci CVP is for the steepest hills. The highest ratio is for
the greatest speed. Shifting from an easier, “slower” ratio to a harder “faster” ratio
is called an upshift. Shifting from a harder, “faster” ratio to an easier, “slower”
ratio is called a downshift. It is not necessary to shift ratios in sequence. Instead,
find the “starting ratio” for the conditions –a ratio that is hard enough for quick
acceleration but easy enough to let you start from a stop without wobbling – and
experiment with upshifting and downshifting to get a feel for the different ratios.
At first, practice shifting where there are no obstacles, hazards or other traffic, until
you’ve built up your confidence. Learn to anticipate the need to change ratios and
change to a lower ratio before the hill gets too steep. Once you’ve learned the
basics, experience will teach you which ratio is appropriate for which condition,
and practice will help you shift smoothly and at precisely the optimum moment.
If you have difficulties with controlling the ratio on your NuVinci CVP, the problem
could be mechanical adjustment. See your dealer for help.

Refitting the Rear Wheel
a. Put the chain on the freewheel; orient
the axle flats so the axle can enter the
dropouts; and place the wheel in the
dropouts.
b. Install the no-turn washers on each axle
end. Orientation of the no-turn washer tabs
is determined by chain length. Place the
tabs behind the axle only if there is not
sufficient room in front.
Improper installation of the
no-turn washer will result in damage
to the dropout and the hub.
c. Grease the o-ring and the adjacent
shoulder on the shift rod and thread the
shift rod into the drive side axle by rotating
it clockwise until it stops and the shift rod
shoulder is flush with the axle.
Only use your fingers to install,
and be careful not to bend or
damage the end of the shift rod.
d. Keeping the main shaft nut tight against
the shift rod retainer nut, screw the
shift rod retainer nut onto the drive side
axle and tighten with an 11mm socket
and torque wrench to 20Nm (15 ft. lbs.)
e. Screw the acorn nut onto the non drive
side axle, but do not tighten.
f. If applicable, attach the roller brake arm
to the bike frame clamp. Do not fully tighten
the bolt until the wheel is secured in the
frame; then tighten the bolt to the torque
specified by the brake manufacturer.

g. Pull the wheel back in the dropout,
tightening the chain to the desired level.
Pull back on the shift rod
retaining nut, not the shift rod.
h. Keeping the wheel centered, tighten the acorn
nut with a 15mm socket and torque wrench to
40Nm (29 ft. lbs.).
Over-tightening may damage parts.
Under-tightening will result in the axle
sliding in the dropouts.
i. Still holding the wheel tight, tighten the main
shaft nut with a 21mm crows foot and torque
wrench to 50Nm (37 ft. lbs.).
Reinstalling the rear pulley housing
NOTE: If the control cables have
been pre-installed on the Cruise-
Controller and rear pulley housing
assembly, follow steps a, b and c.
If not, turn to the CruiseController
Installation section of this manual.
a. Rotate the shift rod clockwise with
your fingers until it stops; this is full
overdrive.
Be careful not to bend or
damage the end of the shift rod.
Only use your fingers.

b. Rotate the CruiseController
until the Inchworm is flat. Gently
slide the rear pulley housing onto
the shift rod, with the cable housing
facing forwards.
c. After aligning the rear pulley
housing with the shift rod, push it
onto the shift retainer nut until the
three lock tabs are fully engaged.

Lubrication
The NuVinci CVP is equipped with a special traction fluid that is
considered to be permanent lubrication. Unauthorized removal
and replacement of this fluid will void the warranty and may
result in damage to the CVP.
Cleaning
Regular cleaning of the NuVinci CVP exterior is recommended.
However, do not use water under pressure (such as a power washer)
as a method of cleaning. This may cause water penetration, which
can lead to a malfunction of the hub.
The exterior of the NuVinci CVP and CruiseContoller should be cleaned
with a mild detergent. Use of aggressive or abrasive cleaners could result
in deterioration of the finish. Keep the hub free of winter road salt.
After cleaning spray some oil or Teflon on the rubber seals around the axle.
This will avoid a squeaky sound when the bike is slowly moved.
Repairs
Only a qualified bicycle dealer should perform work on the NuVinci CVP or the
CruiseController. Unauthorized work could endanger you and may cause your
warranty to become void. Contact a qualified bicycle dealer if you have
problems or questions about the NuVinci CVP or CruiseController.
Cable Change
If your shifter cable needs to be replaced, contact a qualified bike dealer.
