SAFETY INFORMATION
Important Composites
Message
Your bike (frame and components) is made
from composite materials also known as
“carbon fiber.”
All riders must understand a fundamental
reality of composites. Composite materials
constructed of carbon fibers are strong
and light, but when crashed or overloaded,
carbon fibers do not bend, they break.
For your safety, as you own and use the
bike, you must follow proper service,
maintenance, and inspection of all the
composites (frame, stem, fork, handlebar,
seat post, etc.) Ask your Cannondale
Dealer for help.
We urge you to read PART II, Section D.
“Inspect For Safety” in your Cannondale
Bicycle Owner’s Manual BEFORE you ride.
You can be severely injured, paralyzed
or killed in an accident if you ignore this
warning.
Inspection & Crash Damage
Of Carbon Frames/Forks
After A Crash Or Impact:
Inspect frame carefully for damage. See
PART II, Section D. Inspect For Safety in
your Cannondale Bicycle Owner’s Manual.
Do not ride your bike if you see any sign
of damage, such as broken, splintered, or
delaminated carbon fiber.
Any of the following may indicate a
delamination or damage:
• An unusual or strange feel to the
frame
• Carbon which has a soft feel or
altered shape
• ·Creaking or other unexplained noises,
• Visible cracks, a white or milky color
present in carbon fiber section
Continuing to ride a damaged frame
increases the chances of frame failure,
with the possibility of injury or death of
the rider.

Servicing
This supplement may include procedures
beyond the scope of general mechanical
aptitude.
Special tools, skills, and knowledge may
be required. Improper mechanical work
increases the risk of an accident. Any
bicycle accident has risk of serious injury,
paralysis or death.
To minimize risk we strongly recommend
that owners always have mechanical
work done by an Authorized Cannondale
Dealer.
Intended Use
The intended use of
all models is ASTM
CONDITION 3,
Cross-Country.
Please read your Cannondale Bicycle
Owner’s Manual for more information about
Intended Use and Conditions 15.
Tightening Torques
Correct tightening torque for the fasteners
(bolts, screws, nuts) on your bicycle is very
important to your safety. Correct tightening
torque for the fasteners is also important for
the durability and performance of your bicycle.
We urge you to have your dealer correctly
torque all fasteners using a torque wrench. If
you decide to torque fasteners yourself always
use a torque wrench.
Find Tightening Torque Information:
The wide range of bicycle models and
components used means that a listing of
tightening torque would be out of date by
the time it was published. Many fasteners
should be installed with a thread locking
adhesive such as Loctite®.
To determine correct tightening torque
and any adhesive application for a
fastener we ask you to check:
• Many components are marked.
On-product marking is becoming
common.
• ·Torque specs in the component
manufacturers instructions shipped
with your bicycle.
• Torque specs listed on the websites of
component manufacturers.
• With your dealer. Dealers have access
to current data and have experience
with correct torque for most
fasteners.

Maximum Fork Length
Maximum Fork Length is an important frame safety testing specification for front suspension
mountain bikes. You must observe the measurement when installing headset parts, headset
adapters, installing and adjusting a fork, and selecting replacement forks.
To Center Of
The Fork Axle
From
Bottom Of Frame
Head Tube
Maximum
Fork
Length
You must select a replacement fork not only based on head tube diameter but the critical
factor of frame maximum fork length.
Do not exceed maximum fork length. Exceeding the MAXIMUM FORK LENGTH limit can
overload the frame causing it to break while riding. Your retailer MUST follow and observe
this specification for your bike.
You can be severely injured, paralyzed or killed in an accident if you ignore this warning.

EnglishScalpel - Owner’s Manual Supplement
Minimum Seat Post Insert
Make sure at least 100 mm of the seat
post is inserted into the frame at all
times.
Failure to insert the seat post at least 100
mm can place a very high stress on the
seat tube top tube junction causing the
frame to fail while riding.
Remove the seat post. Measure 100 mm
from the bottom of the seat post. Use a
permanent marker to mark the post at 100
mm.
When adjusting the seat post height in
the seat tube, never adjust the seat post
so that the line you mark is above the top
edge of the seat tube.
You must also be aware that bicycle seat
posts are permanently marked by the
manufacturer with a “minimum insert”
line on the seat post itself. You must not
rely on this marking as an indication of the
proper minimum seat post insertion depth.
You can be severely injured, paralyzed
or killed in an accident if you ignore this
warning.
Rear Shocks
Select only compatible shocks and forks
for your bike. Do not modify your bike in
any way to mount one.
Have your shock or fork installed by a
professional bike mechanic
Riding with the wrong rear shock can
damage the frame. You could have a
serious accident. Make sure the total
travel, eye-to-eye length, and stroke length
of the rear shock you select meet the
“Specifications” listed in this manual.
When selecting dierent shocks or forks
for your bike, make sure that the shock
or fork you select is compatible with your
bike’s design and how you will use your
bike.
You can be severely injured, paralyzed
or killed in an accident if you ignore this
warning.

EnglishScalpel - Owner’s Manual Supplement
Tire Size x Maximum Width
Observe the Tire Size x Maximum Width for your bike found in the “Specifications” page of
this manual.
Mounting the wrong size tires can result in the tires hitting the fork or frame when riding. If
this happens, you can lose control of your bike and you can be thrown o, a moving tire can be
stopped because it touches the fork or frame.
Do not mount oversized tires, ones that rub or hit the fork or frame, ones that result in too little
clearance, or ones that can hit the fork or frame, saddles, seat post, or seat post clamps seat post
when the suspension is fully compressed or when riding.
Take care that the tires you select are compatible with your bike’s fork or frame design. Also, be
sure to follow the manufacturer’s recommendations of your front fork and rear shocks.
When you are considering tires for your bike consider...
The actual measured size of a tire may be dierent than its sidewall marking. Each time you
mount a new tire, take the time to inspect the actual clearance between the rotating tire and all
parts of the frame. The U.S. Consumer Product Safety Commission (CPSC) requires at least 1/16”
(1.6 mm) tire clearance from any part of the bike. Allowing for lateral rim flex and a wheel or rim
that is out-of-true will likely mean choosing a rear tire that provides even more clearance than the
CPSC recommends.
Ask your authorized brand retailer for the right tires for your bike and its particular
components! You can be severely injured, paralyzed or killed in an accident if you ignore this
warning.

Cable Routing
The Scalpel has tube in tube routing in the
rear triangle, which feeds into a rubber hose
that is inside the downtube of the front
triangle.
Steps for installation:
1. Both the fork and the swingarm should
be disconnected from the main frame to
allow cable routing access.
2. Install the dropper post according to the
manufacturer‘s recommendation.
a. Route the cable for the dropper post
from the seat tube into the downtube.
Ensure that the cable routes over the
bottom bracket rather than around it.
b. Route the portion of the dropper cable
inside the downtube within the 9mm I.D.
foam tube, similar to what is seen in the
image below.
CBRT1
c. There is a cable tie guide located on
the back wall of the “garage” inside of
the front triangle. Cable tie the dropper
cable to this guide. This makes sure the
cable does not rub on the front of the
chainstay during suspension movement.
CBRT2
d. TIP: run this cable guide slightly loose
so that the cable can slide through it for
dropper post height adjustments.
3. Install the “cable funnel” onto the
bottom of the chainstay.
