warranty beginning on the date of
purchase. This warranty is subject
to the following conditions:
3.

1. IDuring the warranty period,
SRAM components with material
or production defects which as
a result adversely affect the
proper functioning of such components, shall either be repaired
or replaced with a functioning
SRAM component free of charge,
whereby we are free to determine whether repair or replacement should take place. If a
component cannot be replaced
or repaired, the purchaser shall
receive, free of charge, a
5.
component of higher value from
the current SRAM product line.
Defective components which
have been replaced become the
6.
sole property of SRAM.
2. Any other warranty claims not
included in this statement are
void. This especially includes
any disassembly or assembly
14
costs (for instance by the
dealer), which shall not be
covered by SRAM.
Warranty claims are only valid
upon presentation of a proper
proof of purchase.
Parts subject to normal wear and
tear (for example brake sleeves,
brake pads, chains etc.) and
damage which is caused by
improper use, specifically
caused by disregard for our
assembly and operating instructions, shall not be covered by
this warranty. Furthermore, this
warranty shall not cover
damages caused by the use of
parts of different manufacturers
or otherwise which are not
compatible or suitable for use
with SRAM components.
The servicing of a valid warranty
claim shall neither extend this
warranty nor establish a
warranty period.
If a defect is discovered, please
contact the dealer where the

MAKE IT SHINE!
KEEPING YOUR
BIKE CLEAN
CLEANING OF
SHIFTERS
Keeping your bike and
components clean and correctly
lubricated willkeep performance
highand usually slow down the
wear and tear on parts.
We recommend that the internal
cleaning and lubrication of shifters
should only be done when shifting
performance has deteriorated due
to excessive contamination.
We have found that, generally, the
deterioration of shifting efficiency
starts with the contamination of the
cable and housing system.
This causes high friction buildup in
a shifting system and should be
examined first.
HOW THE
PROS DO IT
Wanna know how the pros do it?
Use mild soap and water and a
large sponge or soft brush to
gently work off the mud and crud.
Then rinse with a clean water
sponge bath.
THINK OF RELUBRICATING
After the cleaning of any
component, always properly
re-lubricate if required.
Caution: Be careful how you use
degreasers, citrus or otherwise,
on your bike components.
Degreasers can bloat, soften, or
otherwise damage parts.
KEEP THE BIKE ON
BOTH WHEELS
Always keep the bike on both
wheels when cleaning with water.
Hanging the bike vertically or
upside down to hose it clean can
lead to waterdrainage into now
vulnerable components. Pay and
spray? Avoid it. Quick rinses at the
16
car washor even spraying with
a garden hose can drive
contaminants past the sealed
mechanisms of your components.
Thiscould compromise their
performance and shorten their
lifespan.

SPECTRO 3x7
SPECIFICATIONS
3-speed-hub with 7 speed sprocket cassette
Type MH C3721F
Spectro 3x7 combines the best of the two
gear shifting principles – chain (derailleur)
and hub gears – in an intelligent system.
Because all 21 speeds are changed on the
back wheel the installation of a chain guard
on the chain wheel is possible.
Gear shifting is performed by means of the
ergonomically-designed rotational shifter –
Spectro Grip 3x7.

b) Derailleur: Set right-hand shifter on
handlebars to gear position “7”. Feed
shifter cable through outer stop on the
lower rear wheel fork and push on cable
housing. Then route shifter cable through
adjuster barrel and the clamping bolt to the
derailleur unit. Pull shifter cable taut and
tighten clamping bolt. Make sure that the
cable housing is correctly seated in the
adjuster barrel and outer stop (Fig. 14).
Determination of chain length (see Fig. 14a)
• Place chain over front chain wheel and
the largest rear sprocket and add two
chain links.
• Close chain
SHIFTING
ADJUSTMENT
Hub
• To adjust, the cable must be tightened up
in 3rd gear so as to transmit the shifting
movement directly to the hub. Check
whether the ends of the cable housings
are correctly located in the outer stops.
Adjustment:
• Put shifter into gear position “3”, rotate
pedals to make sure that the gear is
actually engaged.
• Push adjuster sleeve (10) far enough onto
the small pull rod (11) until the cable is taut
(Fig. 15) but without pulling the small pull
rod (11) out of the chain guide nut (12).
Chain

Advice:
Do not use greasy materials when fitting the
left and right-hand fixed grips (2) onto the
handlebars
• Feed the control cables through the cable
housings and the double outer stops. In
doing this ensure that the cable housings
are located properly into the bottom of the
adjuster barrels and the outer stops and
that these are tightly screwed to the down
tube (Fig. 11). Fit the double pulley clip
directly above the bottom bracket on the
seat tube and feed the shifter cable over
the pulleys to the rear (Fig. 11).
• If a cable guide is fitted beneath the
bottom bracket, press the shifter cables in
the pregreased pulley guides and route
them to the rear – please do not use open
designs, otherwise the shifter cable could
slip out when loose. For assembly a hole is
bored in the bottom bracket housing and
the cable guide is screwed tight (Fig. 12).
• Connect control cable with hub and
derailleur
Technical information may be enhanced without prior notice. Released 10/98.
Checking:
• Set shifter to gear position “1”. Rotate
pedals to make sure that 1st gear is
actually engaged.
• Check whether the small pull rod can be
pulled even further out of the chain guide
nut.
• If yes, retension the cable pull, see 1st
adjustment.
• Check again.
Advice:
If the adjustment is incorrect a short jerk
can occur when starting or there may be a
slight creaking noise which may be heard in
the drive system (this does not mean that a
defect exists).
Derailleur
Presetting the derailleur
(best done without the chain)
• Move upper chain guide pulley to beneath
the smallest sprocket (and hold it there),
then turn the limit screw H in or out until
21
SPECTRO 3x7
the guide pulley lines up with the center of
the smallest sprocket (see Fig. 16).
• Move upper chain guide pulley to beneath
the largest sprocket (and hold it there),
then turn the limit screw L in or out until
the guide pulley lines up with the center of
the largest sprocket (see Fig. 17).
• Slowly move the derailleur gear by hand
back to below the smallest sprocket.
• The derailleur is fitted with an adjusting
screw which permits the gap between the
chain guide pulley and the sprockets to be
adjusted. When adjusting with the chain
fitted and the upper chain guide pulley
below the largest sprocket, set the gap in
such a way that when pedalling backwards
the pulley just runs clear of the sprocket.
17
18
Fine tuning of the derailleur:
• Set right-hand shifter to gear position “7”.
This position corresponds with the chain
on the smallest sprocket.
• Rotate pedals. If the chain already touches
the 2nd sprocket or if it shifts onto it,
screw adjuster barrel 1 (see Fig. 20)
clockwise until the contact noise stops and
the chain shifts back onto the smallest
sprocket.
• Set rotational shifter to gear “6”,
sthereby rotate pedals.
• If the chain does not shift, turn adjuster
barrel (1) in an anti-clockwise direction
(see Fig. 20), in other words increase the
cable tension until the chain shifts
correctly onto the 2nd sprocket.
19
Checking the gear shifting system:
• Rotate pedals forwards and check by shifting through each of the gears in turn in
both directions adjusting as necessary.
A
Advice:
If in the course of time further adjustments
become necessary the adjuster barrel A
(Fig. 19) on the right-hand rotational shifter
can also be used.

DISMANTLING AND
A S S E M B LY O F T H E H U B
Dismantling and reassembly of the hub: See
the assembly instructions for the freewheeling hub Spectro T3. The exploded
drawing (Fig. 22) shows the exact installation
position and direction of the individual parts.
MAINTENANCE/
SERVICING
Spectro Grip 3 x7, cabel replacement
• Remove cap (1, Fig. 21) from assembly window (2). Turn rotational shifter forwards to
its stop until the cable head (3) is visible in
the assembly window. Push head out of the
cable guide and remove control cable. Insert new control cable, fit on frame accordingly and pull as far as stop in the cable
guide on the shifter.
Connect control cable with adjuster sleeve
or derailleur and close assembly window.
Adjustment (see page 21/22).
Advice:
When replacing a shifter cable, always
replace the cable housing with new,
compressionless housing.
Derailleur
• Lubricate slider under bottom bracket
(control cable guide).
• Clean chain as necessary and oil lightly.
• Chain links must always be flexible.
Hub
• The 3 speed hub is sufficiently lubricated.
• Oil control cable and small pull rod
occasionally.
• Do not apply water under pressure to hub
gears when cleaning (e.g. strong water jet,
high-pressure cleaner etc.) – if water
does penetrate the unit it could lead to
functional problems.
• If the side play on the rear wheel is too
great arrange for a specialist to adjust
the bearings.
• If the bicycle is not used for long periods
set the rotational shifter to gear position “3
or 7” to relieve the pressure on the system.

LACING AND
INSTALLING HUB
Advice:
a tool can be used to hold the hub in the
vice. This tool threads into the hub’s axle.
Tool part No. 00 2324 002 000.
• Maximum spoke diameter: 2.0 mm
• Please note: Alignment spoke/Nipple
The high flanged hub results in a relatively
tangential running spoke for three crossed
spokes. Some rims do not allow for the flat
angle of spoke nipple. This results in an
undesirable kink between nipple and spoke
(see Fig. 9).
In order to make sure that the spoke and
nipple align, we recommend the following
alternatives:
• Choose the appropriate combination of
nipple and rim
• Cross spokes twice instead of 3 times
• Use embossed rims

Spoke length:
• For examples, refer to spoke length table.
• For hub dimension used to determine spoke
length, refer to page 26.
• On request, we can determine the most
appropriate spoke length for your specific
application needs. For this, we would need
the dimension for rim Ø “A” (see Fig. 10 –
measurement on the basis of two opposing
spoke nipple heads).
• Calculated spoke lengths are approximate
values. They must be checked through
lacing attempts and adjusted accordingly.

Cleaning parts:
• Only brake components, brake cylinder,
brake ams, cylindrical rollers, toothed lock
washer, locking disc and roller guide ring
with stop notches should be degreased in
the cleaning bath. Do not under any
circumstances clean the friction springs
with solvent or degreaser.
• Only clean axle assembly with shifting
component and gear assembly on the
outside using a paintbrush to prevent
degreasing inaccessible lubricating points.
Technical information may be enhanced without prior notice. Released 10/98.
Lubricating parts:
• On the gears, wet the inside sun wheel
catches and outside ring gear catches with
a drop of oil.
• On the axle with shifting component, oil
the shifting cam rods in the axle profile
and around the “prongs” of the shifting
sleeve on both sides. Fill each of the four
recesses around the circumference of the
shifting sleeve with one drop of oil. Using
the shift cable, turn the cable pulley
several times and make sure it does not
jam – all shifting rods in the axle profiles
must move at least once. Do not let go of
the shifter cable other-wise the cable
pulley could fly back at full force (risk of
injury).
• Only coat the diamond-patterned side of
the brake cylinder with grease. Line the
brake cylinder and bearing shell for the
ball retainer in the hub shell with grease.
Special grease ref. no. 0369 135 100.
• Grease the toothed side of the toothed lock
washer a little bit.
Special grease ref. no. 0369 135 100.
• Thoroughly grease the seat of the friction
spring on the axle as well as the inside and
outside of the friction spring itself
(13, Fig. 27). Be sure to use special grease,
ref. no. 0369 148 015.
• Wet brake cams, cylindrical rollers and
roller guide ring with a resin-free, acidfree oil.
• Replace faulty or worn parts.
• If worn, i.e. diamond pattern can hardly be
seen, the brake cylinder must be replaced.
The three brake cylinder segments only fit
perfectly on top of one another in one
particular order. Therefore it is a good idea
to mark the segments before removing the
circlip (Fig. 23).
• Correct assembly of springs (8a) for the
catches (8c) on the roller guide ring
(9, Fig. 24)

OPERATION/SHIFTING
Replacing Clickstick – hub cable/
replacing wheel
If the short Clickstick cable is damaged
(spring shell to hub), the rear wheel must be
removed. This entails observing the following
instructions which are also valid for wheel
replacement in the case of a flat tire.
• Disconnect shifter cable from Clickstick by
unhooking cable clamp assembly
(5, Fig. 30)
• Push clip (12) back from chainstay, loosen
or unscrew axle bolts (13), remove
fastening bolt (14) of brake lever clamp

sensitive or grabs (only for Type MH 12110),
the brake shell should be lubricated with the
designated lubricant (Art.-No. 0369 135 100).
Overheating the hub can lead to lubricant
loss and an overly sensitive or grabby brake.
For this reason, it is imperative to alternately
use the second brake (front wheel brake)
when on long and steep rides. This will give
the rear brake a chance to cool down.
Caution:
• Locking or skidding wheels can cause a
fall which may result in severe injury as
well as damage to the bicycle. To avoid
this, apply pressure on brake lever or
pedals with care to prevent skidding
wheels.
• If the rear wheel develops excessive side
play, have the bearings read-justed by a
professional.
Hub
• When cleaning your bike, do not expose
hub to compressed water (i.e. high
pressure hose, etc.) If water gets into
system, malfunction may occur
• The 12-speed hub has been
factory lubricated.

.
MAINTENANCE/
SERVICING
• The Spectro S7 is provided with
permanent lubrication and under normal
conditions is maintenance-free. If the
brake is loaded excessively its effect can
be too strong. In such a case the brake
shell should be lubricated with a special
grease. Keep the pawl pockets free from
grease. (Art. no. 0369 135 100)
After completely dismantling the hub the
following items should also be noted:
1. Cleaning of parts:
• All parts – except for the planetary gear
carrier – can be degreased in a cleaning
bath.
• The planetary gear carrier only needs to
be cleaned on the outside with a brush so
as not to degrease the planetary gear
bearing.
i n s t r u c t i o n s
TYP H 7225
(DRUM BRAKE)
18
2. Lubrication of parts:
• To lubricate the bearing points on the
planetary gear sets, position the planetary
gear carrier on its crown and apply 2–3
drops of oil to the bearing bolts – at the
same time turning the planetary gears so
that the bearing points are completely wet.
Oil axle through the axle bore and axle
slot, apply a thin coating of grease to the
outside.
• Oil the inside of the sun gears, grease the
outside teeth (fill the gaps in the teeth).
• Oil outside teeth and carrier plate on
the coupling gear and lightly grease the
borehole from right and left.
• Do not apply grease to ring gear but just
oil the pawl pockets.
• Grease the brake cone in the borehole and
the friction spring.
• Spread grease on the inside and outside of
the brake shell.
• Regrease ball retainer, line ball bearing
running tracks with grease.
• Fill lever cone with grease reserves for
brakes
Advice:
• If the cycle is not used for a long period
put the shifter into gear position “1” to
reduce the strain on the system.
• Hub gears should not be subjected to
high-pressure water during cleaning (e.g.
strong water jet, high-pressure cleaner
etc.) – any water which penetrates could
lead to functional problems.

located between the three ridges (2a) on
the sprocket (2).
2a
Fitting the wheel
• Put dust cap (1) in place and push
towards the sprocket (2) until
engagement is felt.
• Fit wheel in rear fork, fit non-turn washers
(3, Fig. 8) on both sides. The serrations
must bear against the outside of the
dropouts and the prongs must engage in
the dropout slots.
2a

Advice:
If a chain tensioner is provided fit the nonturn washers (3) so that the serrations bear
against the inside of the dropouts. The fixed
cone (drive side) must always directly bear
against the dropouts.

• Fit protective bracket (4, Fig. 9) directly
below the axle nut on the sprocket side.
• Tightening torque of axle nuts, approx.
35 Nm.
• Fit brake lever clamps (5, Fig. 8)
• Tightening torque: 2–3 Nm.

Thumb Shifter/Clickbox
(Standard version):
• Fit shift rod (5, Fig. 10) on shift tube (6)
(lightly oil all parts) and push into axle
bore to the stop. Apply slight pressure on
the shift rod with its threaded section and
screw inwards in a clockwise direction
until it can again be moved axially.
• Push Clickbox onto the hub axle as far as
10
the stop. Then make sure that the knurled
bolt engages the slot on the hub axle when
tightened up. It is not necessary to adjust
the shifter.
Mini Clickbox (see Fig. 11):
• Assembly of shift rod (8, without head)
and shift tube (9, with slot) is the same as
the standard version.
• First push the adjuster barrel (13) with
guiding rib (12) onto the hub axle – making
sure that the lug (10) is guided into the slot
on the shift tube (11) – until it can be felt to
engage. Turn guiding rib (12) to face
upwards.
• Push Clickbox to the stop on the hub axle.
The guiding rib (12) should then be fully
seated in the slot on the Clickbox housing.
For both versions the following applies:
• After fitting the Clickbox tighten up the
knurled bolt by hand making sure that the
knurled bolt engages with the slot in the
hub axle. Assembly can be carried out
independently of the shifter setting but it is
easiest to assemble the Clickbox in 2nd
gear (without the need to overcome spring
pressure).
Advice:
Shifter adjustment or retroadjustments are
only necessary with the Mini Clickbox. Carry
out adjustment work or check settings after
changing a wheel (e.g. after a flat tire).
Removal of rear wheel:
• Loosen knurled bolts
• Withdraw clickbox, the shift rod/tube can
be left in the hub axle without being lost.
To remove both parts pull shift rod outwards and unscrew in an counter-clockwise direction.
• Remove wheel as normal.

SPECTRO P5
• The Spectro P5 is provide with permanent
lubrication and under normal conditions is
maintenance-free. If the coaster brake is
loaded excessively its effect can be too
strong. In such a case the brake shell
should be lubricated with a special grease
(art. no. 0369 135 100).
After dismantling the hub the following
items should be carried out:
• Oil axle through the axle bore and lightly
grease the outside.
• Lightly grease the inside teeth on the ring
gear – but only oil the pawl pockets.
• Oil coupling gear and carrier plate
assembly on both sides, do not grease.
• Only clean the planetary gear carrier with
a brush (do not put in cleaning bath)
• To lubricate the bearing points on the
planetary gear sets position the planetary
gear carrier on its crown and apply
2–3 drops of oil to the bearing bolts – while
doing this turn the planetary gears so that
the bearing points are completely wetted.
Grease bearing points etc. as normal and
provide lever cone with a grease supply.

Disassembly (see exploded view):
• Unscrew indicator chain (23) (right-hand
thread), remove circlip (21), sprocket (20),
dust cap (19) and hub axle (10) on the
driver side.
• Unlock hexagonal nuts (1) and unscrew.
• Remove brake arm (2), ball retainer (3) and
brake sleeve (4) and remove hub shell (5).
• Remove safety washer (7), thrust washer
(8) and then the planet carrier complete
with brake cone (6). Unscrew the brake
cone from the planet carrier (9).
• Turn hub over.
• Loosen the lock nut (22) and fixed cone
(18) and remove.
• Remove driver (17), spring cover (15),
compression springs (14 and 13) and
ball retainer (16).
• Push the sliding key (12) through the large
bore in the coupling wheel of the ring gear
(11) – the bore and thrust block must
be aligned.
• Remove the ring gear (11) from the axle.
Differences for types H 3105 and H 3125:
See exploded views.
• There is no brake sleeve (4) and brake
cone (6).
• The planet carriers (a) have a cylindrical
shaft instead of a flat thread, which houses
a pawl carrier (b) held by a safety washer
instead of the brake cone.
• Further differences: instead of a lever cone
(2) for type H 3115, an adjusting cone (d)
with dust cap (e) for type H 3105 and a
small adjusting cone (D) and corresponding ball retainer (f) for type H 3125
are fitted.
Working on individual components/
lubricating the parts
Replace defective or worn parts, lubricate or
oil new and cleaned parts as follows:
• The brake sleeve (4) must be replaced in
case of wear, ie diamond pattern hardly
recognizable. Lubricate the inside and
outside of the brake sleeve – pack the ring
shaped groove on the lever cone (2) with
grease, grease the brake cone (6) in the
bore and the friction springs.
• Grease the bearing points of axle (10),
ball retainers (3, 16) and in the driver (17).
Pack the ball tracks of the sleeve (5)
with grease.
• Oil the bearing points of the planet wheels
on carrier (9), grease the outer face of the
teeth.
• Oil the driving plate on the coupling wheel
in the ring gear (11) – grease the bore
lightly
Assembly – See exploded view for fitting
position and direction.
• Clamp the hub axle (10) with the slot for
thrust block upwards), fit ring gear (11) and
align the large bore in the coupling wheel
with the slot. Position the radius of the
sliding key (12) facing downwards and
turn the coupling wheel slightly.
• Fit the compression springs (13 and 14)
followed by the spring cover (15).
• Place ball retainer with balls in (16) on ring
gear (11), mount driver (17), fit fixed cone
and lock with hexagonal nut (22),
tightening torque 15–20 Nm (11–14 ft.lbs).
• Turn hub over and slide on planet carrier
(9) – thrust washer (X) must first be fitted
for types 3105/3125. (For type 3115, this
washer is already integrated in the planet
carrier). Mount thrust washer (8) and place
safety washer (7) in the recess of the axle.
• Screw brake cone (6, type 3111) onto the
flat thread – for types 3105/3125 mount
pawl carrier (b) and secure in place using
safety washer (c).
• Fit hub shell (5) – turning it counterclockwise slightly to get past the stop
notches – until the shell runs cleanly
onto the ball retainer.
• For type 3115, insert the brake sleeve (4) so
that the spring end of the friction spring on
the brake cone (6) sits in one of the two
slots on the brake sleeve. Insert the ball
retainer and fit the lever cone – move the
lever cone lightly to and fro until the lugs
on the brake lever catch in the grooves on
the adjusting cone.
• Adjust the hub clearance by screwing on
hexagonal nut (1) until the hub shell runs
free of play but not under tension. Lock
with a second nut to a tightening torque of
15…20 Nm (11–14 ft.lbs.).
• For type H 3105 insert ball retainer (3),
mount adjusting cone (d) with dust cap (e)
and hexagonal nuts (1). Adjust the hub
clearance as for type H 3115.
• For type 3125, the ball retainer (f) and
dust cap (pressed in) normally remain in
the hub shell. The hub clearance is set
with adjusting cone (D) as for type H 3115.
For notes on fitting the brake carrier,
please refer to mounting drum brake.
Caution:
Use special grease, order no. 0369 135 100
and standard bike oil.
Only oil – do not grease – the stop notches/
stop notch cases on ring gears (11), pawl
carriers (b) and brake cone (6).

Type H 3115 with coaster brake:
improved braking in third gear after
production date CW 38/96.
• In case of repair, older hub (Fig. 16)
models can be converted with a repair
set. It is important that all three parts are
replaced at the same time – new,

A change with of the new or converted hubs:
when braking in third gear, the tension chain
moves out of the chain guide nut by approx.
one chain link – after braking, the tension
chain returns immediately to its normal
position. (Fig. 18)
The Spectro hubs are equipped with
permanent lubrication and are maintenancefree under normal conditions. For type
H 3111, however, particularly high loading of
the coaster brake can cause it to overcompensate. In this case, apply special
grease to the brake sleeve.
During transportation or longer periods when
the bike is not used, shift the hub into third
gear to relieve the system of load.
Do not clean gear hubs using water under
pressure (e.g. sharp water jet, high pressure
cleaner etc.) – water in the system can cause
it to malfunction.

Advice:
The new brake sleeve, recognizable by the

MAINTENANCE/CARE
OPERATION
• The hub mounting is sufficiently lubricated
and essentially maintenance-free.
• Lubricate brake cable regularly.
(Cable housing without inner tube.)
• Do not clean hub with water under
pressure (e.g. hard jet of water, highpressure cleaner etc.) – water penetrating
could produce corrosion in the brake
drum and cause malfunctioning.
• Do not rinse hub with benzene, petroleum
etc. as this could produce impurities in
the brake pads
• If the front wheel develops too much
lateral play, have the mounting adjusted
by a specialist.
• The drum brake can be controlled very
precisely and provides very effective
braking deceleration compared with
conventional bicycle brakes. However, the
drum brake only reaches maximum braking
power after a certain 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.
Advice:
The front brake is usually applied using the
brake lever on the right of the handlebars.
Some bicycle manufacturers may, however,
fit the front brake lever on the left side.
SAFETY
Important!
• If the bicycle is left standing for long
periods, surface rust in the brake drum
may increase braking 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.
• On long, steep downhill stretches, also
use the second brake (rear wheel)
alternately to prevent the brakes from
heating up excessively.
• Do not touch hub after cycling – risk of
burning!
• If retrofitting the VT 3/5000, the front fork
must meet the strength requirements for
drum brake hubs.

• After all the components have been fitted,
actuate the brake lever strongly several
times and then check the brake setting.
The instructions of the brake or component
manufacturer must be followed.
Caution:
Do not unscrew the adjusting screw (5) for
adjusting the brake by more than 4 mm
(danger of breakage) – rather carry out the
adjustment on the brake itself. Always
counterlock the safety nut (6) against the
lever housing.
Advice:
Using adjusting screw (4) (2 mm Allen
screw), the grip width (X) of the hand lever
can be individually adjusted ("reach adjust").
Any play in the hand lever can be adjusted
using Allen screw (8). The hand lever must
continue to move freely, however.

MAINTENANCE/CARE
• Regular lubrication will extend the
chain's service life
• Apply oil to the chain rollers and allow
to work in
• Clean dirty chains before oiling.
• Do not use any grease-dissolving or acidic
agents. Cleaning agent must be rinsed off
after a few minutes with water. Apply oil
after chain is completely dried.
Caution:
• Make sure the retaining spring on the chain
lock resp.Power Link is locked exactly into
place.
• Always use a new chain lock resp. Power
Link when fitting a new chain. Failure to
shorten the chain properly or to lock it
exactly into place may cause damage to the
chain and eventually total chain failure,
material damage or the rider to fall off his
bicycle resulting in injury.
• Worn sprockets should also be replaced
when a new chain is fitted.
Closing chain (Power Link and
Power Link II connecting links):
• …every chain is only as strong as its
weakest link – traditionally this is the
connecting link. In contrast, the Power Link
connection is just as strong and durable as
every other link in the chain. And it can be
opened and closed as many times as you
want without using tools. Fit chain, bring
the two ends together and insert both
halves of the Power Link into the chain
ends. (Fig. 6)
• Press both halves of the connecting link
together (Fig. 7) and lock in place by
pulling the chain apart. (Fig. 8)
• To disassemble: Press both plates of the
connecting link together (Fig. 7) while
sliding the chain ends together (unlock).
Remove the two halves of the link from the
chain ends.
Caution:
• “Power Link” (black) only for chain PC 41
• “Power Link II” (grey, “PL II” marked on the
plate) only for chains PC 31, PC 31S
