About This Supplement
Cannondale Owner’s Manual Supplements provide
important model specific safety, maintenance, and
technical information. They are not replacements for
your Cannondale Bicycle Owner’s Manual.
This supplement may be one of several for your bike.
Be sure to obtain and read all of them.
If you need a manual or supplement, or have a
question about your bike, please contact your
Cannondale Dealer immediately, or call us at one of
the telephone numbers listed on the inside cover of
this supplement.
You can download Adobe Acrobat PDF versions of
any Cannondale Owner’s Manuals or Supplements

Explicit Definitions
In this supplement, particularly important
information is presented in the following ways:
WARNING
Indicates a hazardous situation which, if not
avoided, could result in death or serious injury.
NOTICE
Indicates special precautions that must be
taken to avoid damage.

Tandems are Different from
Single Rider Bikes
WARNING
TANDEMS ARE BIGGER, HEAVIER, AND LESS
MANEUVERABLE THAN SINGLE RIDER BIKES.
■Ride very cautiously as your team climbs the
tandem learning curve.
■More time is needed to react and avoid
ride hazards.
■Always think further ahead. Allow more time.
Learn to anticipate hazards.
Tandem riding, like any bicycle riding carries a
risk of serious injury, paralysis or death.
Tandem Specific Forks Only
The front fork of your Cannondale Tandem is
specially designed to be much much stronger than
a regular bike fork. One of the reasons it is much
stronger is that braking a tandem subjects the frame
and fork to tremendous stresses. Ordinary forks can
buckle or fold under tandem braking conditions.
Any fork used on your tandem must be designed
and intended specifically for tandem use!!
WARNING
Confirm with all component manufacturer’s
that the components chosen are designed and
intended for use on a tandem bike and intended
for your weight and riding style.
Tandems weight more and often are ridden
faster than single bikes so many components
must be designed for higher speeds and
larger loads.
Both riders can be seriously injured, paralyzed,
or killed In a resulting accident if you ignore this
warning.

WARNING
TO PREVENT THE STOKER HANDLEBAR SYSTEM DETACHING, MOVING, ROTATING, OR TWISTING
UNEXPECTEDLY OR SUDDENLY WHILE RIDING :
Before Each Ride: Check all bolts. Use a torque wrench when tightening the bolts of the stoker/captain
seat post and handlebar assemblies. Follow the manufacturer’s torque instructions for your particular
handlebar/stem/seat post components.
At Least Annually: Remove, clean and inspect the captains seat post. Replace it with a new one if it is
damaged. Also, clean and inspect the Stoker’s handlebar assembly. Make sure it is in good condition.
Replace it with a new one if it is damaged.
EXTENSION: If the stoker handlebar assembly is the extension type, never extended it beyond the
“MINIMUM INSERT” or MAXIMUM EXTENSION” line.
If you do not understand these instructions or are unable to complete them as described, please have the
performed by a professional bike mechanic.

TANDEM RIDING
The Tandem Partnership
Tandems are fun, and with two engines for the same frontal area, they’re considerably faster than single
bikes. Tandem teams learn to ride together well, to communicate without words, and to anticipate each
other’s desires. Tandeming is a great way to enjoy cycling with another person.
Tandems are serious business too. One rider (CAPTAIN) is entirely responsible for the well-being of the other
rider (STOKER). The bike is bigger, heavier, and less forgiving of sloppy riding habits. A tandem captain can’t
be as spontaneous as a rider on a single, nor can the captain make the same kinds of last-minute recoveries
from errors in judgment. Look farther ahead, plan farther ahead.
Also, be aware that tandems attract attention. People will stare, wave, shout. Passing cars, temporarily
distracted, will often swerve in or out. The presence of a tandem can make people act dierently on the road.
A bell or airhorn can be very handy in trac.

The Captain’s Responsibility
The captain’s primary job is to make the stoker happy. With an unhappy stoker, the captain won’t have
a riding partner! So you must reassure your partner with careful, methodical riding habits. Anticipate
maneuvers, beginning them far in advance. Be alert to shifting needs. A too-fast or too-slow cadence is
doubly annoying to the stoker because she/he can’t fix it. Watch the road or trail ahead, and make your
steering and braking corrections smoothly.
Ride slightly farther from the curb, or from parked cars, than you would on a single bike. Your stoker doesn’t
want to feel hemmed in. If you ride too far to the right, you may find your stoker leaning to the left, trying to
veer away from the curb.
When you conduct a maneuver, such as merging across trac to make a left turn or steering around a
pothole, make your decision early. Signal your intentions clearly, proceed on a straight path, and complete
the maneuver. A decisive captain will ride smoother, and that will make the stoker happier.
Most new tandemists find captaining exhausting, and they get sore shoulder muscles from being tense. This
too will pass. As you become accustomed to the requirements of captaining a tandem, you’ll develop a
light touch.
Don’t hot dog. If your stoker is nervous, ride slowly. In time, the stoker may become more confident and ask
for more speed. But if she/he wants to go slow, go slow! The more conservative voice must prevail. That’s
only fair. Remember, you’re the chaueur, not the stunt pilot.
The Stoker : The Best Seat in The House
The back seat on a tandem is the fun seat. You have this person in front of you who’s giving all his/her
attention to making you feel comfortable. The view is terrific out to the sides, just like on a train ride. The
view to the front may be a bit bland, but the captain’s jersey pockets are a great place to put your fruit bars,
and other hedonistic goodies.
Your obligations are few: Pedal—at an agreed-upon eort level. Pedal smoothly, so your pedaling doesn’t
make your upper body move around. Don’t shift your upper body weight abruptly. (Your weight shift can
inadvertently steer the bike, and force the captain to fight you.) Hold your head high and enjoy the scenery.
Tell your captain what she/he is missing while she/he keeps eyes glued to the road for potholes.
Many tandem teams delegate hand turning signals to the stoker. This not only encourages communication
between the stoker and the captain, it also allows the captain to concentrate on the steering and braking
involved in making the maneuver.
Every successful stoker learns to delegate authority. The captain steers. The captain decides when to pedal
and when to coast. When coasting, the captain decides where to position the pedals. Never fight the captain
on these matters. She/he is busy giving you a great ride so you can enjoy yourself.

Tandem Bike Fit
In addition to sizing and comfort issues for each individual, the bicycle must be made to accommodate the
interaction between the two riders. This document is meant to oer hints and suggestions but only scratches
the surface of tandem setup. The best configuration for any pair of cyclists on a tandem will be the result of
experimentation. You should investigate the pros and cons of any setup decisions by first consulting with
people or publications which are knowledgeable about tandem bicycles. See page 8.
The captain should fit the tandem as she/he would fit on a single bike. But on a tandem, it’s doubly
important to have 2-3 inches of crotch clearance for the starting and stopping maneuvers described below.
The stoker uses the same seat-to-pedals distance as on a single bike. But the handlebars will be closer (which
is okay, since the stoker doesn’t need to steer).
Getting Underway
Allow time for a complete Pre-Ride Inspection. See your Cannondale Bicycle Owner’s Manual for overall bicycle
pre-ride checks. See the Maintenance section of this supplement for Tandem checks.
Starting Off
Starting and stopping a tandem is smooth and easy, but only if you do everything in the exact prescribed
order. Start by shifting the bike into a comfortably low gear.
The captain mounts first. Before, and only before anyone gets on the bike, it can be leaned over to lower the
clearance to straddle the bike. Swing your leg forward over the handlebars, not back over the rear of the bike.
There might be a person standing there!) Straddle the top tube, plant your feet on the ground, and spread
your legs to clear the pedals. Firmly hold the bike upright and squeeze both brakes.
Never let the bike lean to the side, particularly after the stoker gets on. This is the biggest dierence between
your tandem and your single. (Your single is so light that you don’t think twice about leaning it. The tandem is
not only heavy, it’s top heavy. Once you let it lean a little, the stoker’s weight makes it want to lean more. And
the stoker just hates the way that feels.)
The stoker gets on now. Because the captain is holding the bike rock solid, the stoker can mount it like a
horse. Put one foot on a pedal and swing your other leg rearward over the saddle. Now the stoker puts both
feet in the toe clips or clipless pedals. When you’re ready, the stoker backpedals so the captain’s preferred
starting pedal is in the up position. The stoker says, “ready.”
Now the captain can start. Pick up one foot, put it on a pedal, and stand on it while steering straight ahead.
(Don’t put your rear end on the seat before starting to pedal, because that could make the bike lean over and
wobble, and possibly fall.) After you’ve started the first pedal stroke, get in the saddle, put your other foot
on the backside of the pedal, and continue pedaling and steering. Don’t worry about the toe clip or clipless
pedals. Let the toe clip scrape the ground. Pedal until you are going comfortably fast (10 mph or so), and then
put your other foot in the toe clip or clipless pedals.

Stopping
If you stop briefly, say, for a trac light, the captain stops the bike while the stoker stays strapped in. The
captain takes one foot o the pedal, dismounts from the seat, and puts the foot on the ground while holding
the bike absolutely upright. Starting up again is just like your initial start-up. The captain should let the stoker
know what’s happening —talk to one another —no surprises.
To stop and dismount, reverse the mounting procedure. The captain gets o the seat, spreads legs to clear
the pedals and brace the bike upright while the stoker climbs o. Then the captain can dismount.
Slow Speed Riding
Tandems are stable and easy to maneuver at slow speeds. But they need a confident captain who doesn’t
overcorrect or induce wobbling. A smooth style is the key to good slow-speed riding. After you’ve gotten to
know your tandem well, you’ll find you can make a U-turn on a narrow two-lane road.
Communication
Some tandem teams talk a lot about riding. They inform each other of every bump, every shift, every time
they slow down, every drink from a water bottle. Others almost never talk. They prefer to communicate
silently. Whichever style you pick is up to you. Just pick the one that works for you.
One important coordination activity may require talking, at least at first: shifting. The reason: on a single bike,
riders intuitively let up on the pedals when they’re shifting. On a tandem, the stoker doesn’t necessarily do
that. This is hard on derailleurs (especially front derailleurs) and may make shifts more dicult. Make sure
you both let up on the pedals during critical shifts. Whether you do that by talking or by the stoker feeling
when captain is about to shift is up to you.
WARNING
GOOD COMMUNICATION BETWEEN THE CAPTAIN AND STOKER INCREASES THE SAFETY AND ENJOYMENT OF THE RIDE.
MIS-COMMUNCIATION OR POOR COORDINATION INCREASES THE CHANCE OF BEING INVOLVED IN AN ACCIDENT.
NEW TANDEM RIDERS:
Before riding on a more challenging course, choose an open area free of hazards to practice and develop good Tandem
communication skills.

Riding at Night
Most of tandem safety comes from good technique, which we’ve described above. A few specific warnings
merit mention, though.
Riding a tandem at night is legal if you have a headlight and taillight—but we don’t recommend it. Nighttime
riding is more mentally demanding than day time riding. Tandem riding is more mentally demanding than
single riding. A tandem at night adds up to too much demand, and too small a margin for error. A tandem is a
pleasure vehicle, so use it during day—the most pleasant time to ride.
See your Cannondale Bicycle Owner’s Manual for more
important safety information on riding at night.

Bottom Bracket Eccentric
Your tandem’s has either, a standard 68mm English threaded BB eccentric, or a BB30 Eccentric
assembly (shown next page) depending on the model. Both eccentric types are available from
Cannondale. See Replacement Parts.
The purpose of an eccentric is to enable rotation of the crankset within the shell for the
adjustment of the timing chain, the chain that connect the front BB with the rear BB. The
timing chain must be of the correct length in order to set the tension with the eccentric. See the
Specifications section for timing chain length for your tandem. Timing chain tension adjustment
is explained on the following pages.

Eccentric Maintenance
Annually, as part of your regular maintenance schedule, the crankset should be removed from the
eccentric and the eccentric assembly removed from the frame. At this time, the eccentric should
be disassembled, cleaned and re-greased. The inside the frame BB shell should be cleaned and
re-greased as well. The BB30 bearings should be inspected for proper function and replaced with
new ones if damage is indicated.
Apply a a high-quality bicycle bearing grease to the mating surfaces of the eccentric, the wedges
and inside the frame shell. grease will to help ensure that the eccentric can be rotated within the
shell easily.
Eccentric maintenance should only be performed by a professional bike mechanic.

Periodically, the tension of the timing chain must be checked. The tension should be maintained at 1/2” of total vertical
deflection. Normal chain wear and stretch will cause the tension to change over time.
How to adjust the timing chain tension:
1. CLEAN AND LUBRICATE THE TIMING CHAIN. Cleaning and lubricating the chain will give result in the best measurement.
Ask your Cannondale Dealer about chain care and available products (tools, cleaners, lubricants).
2. MEASURE THE TENSION - On the upper length of the chain in the middle of the front and rear timing chainrings, move
the chain up and down. You should be able to lift it up 1/4” and move it down 1/4.” This is 1/2” vertical deflection.
6.4mm (1/4")
6.4 mm (1/4")
Turn the crank to rotate the wheel so you can check the chain tension at different links of the chain at the same
midpoint. If the chain seems tighter in some places, it may be an indication of chain damage or some other problem.
Have the chain replaced or the damage repaired before attempting any adjustment. If the chain is in good condition
continue to step 3.
3. ADJUST THE TENSION - Insert a 4 mm Allen key through the thread cap into the eccentric fixing bolt and turn it counter-
clockwise to loosen the eccentric. After the first turn or so, the wedge bolt will feel loose then it may seem to tighten as it
pushes the wedge backward freeing up the eccentric to rotate in the BB shell. When the wedge is loose and the eccentric
assembly is free to rotate within the bottom bracket shell , insert the end of an Allen key into one of the eccentric holes
and rotate it until the correct vertical chain deflection is reached. See next figure. The centering bolt of the eccentric
locates on the face of the bottom bracket shell on the drive side to center the assembly. The centering bolt is not an
adjustment; do not remove it.
4. RETIGHTEN THE FIXING BOLT - When the chain tension is set, tighten the wedge bolt to the specified torque.
WARNING
INCORRECT CHAIN TENSION ADJUSTMENT CAN CAUSE YOU TO HAVE AN ACCIDENT. A chain that it too loose
can come off and a chain that is too tight can bind, break or accelerate wear on other parts . Both conditions
can lead to an accident. If you do not understand these instructions or are unable to complete them as
described, please have the performed by a professional bike mechanic.

MAINTENANCE
The following table lists only supplemental maintenance items. Please consult your Cannondale Bicycle
Owner’s Manual for more information on basic bike maintenance. Consult with your Cannondale Dealer to
create a complete maintenance program for your riding style, components, and conditions of use. Follow the
maintenance recommendations given by the component manufacturers for the various non-Cannondale parts
of your bike.
ITEM FREQUENCY
CHECK CHAINS, DERAILLEURS, HEADSETS AND TIRES on Tandems
experience greater wear and tear than on single bikes. These items
should be maintained as on your single bike, but more frequently and
more carefully.
BEFORE AND AFTER EACH
RIDE
CHECK THE STOKER HANDLEBAR SYSTEM. See page 3.
BEFORE EVERY RIDE
TANDEM TIRE PRESSURE is critical. Low tire pressure invites pinch-
cut flats, while high pressure improves your performance and makes
the tires last longer. Use the maximum pressure named on the tire
sidewall.
CHECK CONTROL CABLES are critical. Because of their length on
tandems, cables are vulnerable to poor performance friction or poor
routing. Have damaged (worn, frayed, stretched, broken) cables
replaced with new ones before riding.
EVERY FEW RIDES
CHECK THE TIMING CHAIN TENSION - The timing chain—between
the two cranksets—is unique to tandems. It stretches in normal use,
and must be kept tight. A loose timing chain can flop sideways and
snag a crank arm, or it can come o entirely. See page 14.
Buy a chain wear indicator to know when to replace both chains. A
tandem has a lot of expensive chainwheels and cogs, so the chain
wear indicator will quickly pay for itself.
WARNING
ANY PART OF A POORLY MAINTAINED BIKE CAN BREAK OR MALFUNCTION LEADING TO AN
ACCIDENT WHERE YOU CAN BE KILLED, SEVERELY INJURED OR PARALYZED. Please ask your
Cannondale Dealer to help you develop a complete maintenance program, a program which includes a
list of the parts on your bike for YOU to check regularly. Frequent checks are necessary to identify the
problems that can lead to an accident.
