intended use

All-Mountain

INTENDED for trail riding and riding

uphill. All-Mountain bicycles are more

heavy duty than cross country bikes,

but less heavy duty than Freeride

bikes. All-Mountain bikes are lighter

and more nimble than Freeride bikes.

All-Mountain bikes are heavier and

have more suspension travel than a

cross country bike, allowing them to

be ridden in more difﬁcult terrain, over

larger obstacles and moderate jumps.

All-Mountain bikes are intermediate in

suspension travel and use components

that ﬁt the intermediate intended use.

All Mountain bikes cover a fairly wide

range of intended use, and within this

range are models that are more or less

heavy duty. Talk to your retailer about

your needs and these models.

NOT INTENDED

for Hardcore Freeriding,

Extreme Downhill, Dirt Jumping, Slopestyle,

or very aggressive or extreme riding .

TRADE OFF All-Mountain bikes are

more rugged than cross country bikes,

for riding more difﬁcult terrain. All-

Mountain bikes are heavier and harder

to ride uphill than cross country bikes.

All-Mountain bikes are lighter, more

nimble and easier to ride uphill than

Freeride bikes. All-Mountain bikes are

not as rugged as Freeride bikes and must

not be used for more extreme riding and

terrain.

WARNING

USING YOUR BICYCLE IMPROPERLY IS

HAZARDOUS.

building up a frameset

Before building up a frameset, consult with

your Cannondale Dealer and the component

manufacturers, and discuss your riding style,

ability, weight, and interest in and patience

for maintenance.

Make sure the components chosen are

compatible with your bike and intended for

your weight and riding style.

Generally speaking, lighter weight

components have shorter lives. In selecting

lightweight components, you are making a

trade-off, favoring the higher performance

that comes with less weight over

longevity. If you choose more lightweight

components, you must inspect them more

frequently. If you are a heavier rider or have

a rough, abusive or “go for it” riding style,

buy heavy duty components.

Read and follow the component

manufacturers warnings and instructions.

about freeriding & downhill

WARNING

FREERIDING AND OTHER FORMS OF “EXTREME RIDING” ARE EXTREMELY DANGEROUS.

YOU CAN BE SEVERELY INJURED OR KILLED IN A SERIOUS ACCIDENT.

Freeriding, jumping, hucking, dirt jumping, mountaincross, downhill, slalom, slopestyle,

urban or street riding or other evolving forms of extreme or hard core mountain biking

are inherently dangerous and can lead to serious accidents. Wear all safety gear and be

sure your bike is in excellent condition. Follow all the instructions and warnings below.

These steps will reduce, but not eliminate, the inherent risks. Even with state of the art

protective safety gear you could be seriously injured, paralyzed or killed. If you do not

want to take these risks, do not engage in this type of riding.

Fundamental Risk

Freeriding, jumping, hucking, dirt jumping, mountaincross, downhill, slalom, slope-

style, urban or street riding. It seems that everywhere you look, from Mountain Dew®

commercials to the X-Games® to the Red Bull®Rampage, riders are grabbing big air and

sticking sick drops. And it sure looks fun.

But what the videos and bike magazines and ads don’t always tell you is that extreme

riding takes an amazing amount of skill. Some of the riders you see are well-paid pros

who have gradually built up their skills through endless hours of practice, and who have

also had their share of stitches, concussions and busted bones (and bikes). Others are

daredevils who have chosen to accept or ignore the risks. Would you allow anyone to

say that you are so weak in the head, and have such poor judgment that you copy those

you see in the media without thought of the serious risks?

The stakes are high if you screw up. Realize too late that you aren’t up to the challenge,

and you run the risk of major injury or even – say it aloud – death, paralysis. In short,

extreme riding carries a high degree of fundamental risk, and you bear the ultimate

responsibility for how you ride and what you attempt to pull off. Do you want to avoid

these signiﬁcant risks? Then do not ride this way.

Product Limitations

Problems of pilot error aside, hard-core riding also beats the heck out of your equip-

ment. Although we build and test our bikes to make them tough, there’s no way that

we can guarantee they’ll survive your umpteenth six-foot drop. For starters, there is no

industry “jumping” standard. The many circumstances of takeoff, landing, speed, rider

technique, etc. are unique. The judgment, lack of judgment or insanity of a rider who

may ride a Cannondale bicycle cannot be completely predicted, so it’s ﬂat-out impos-

sible to predict how anyone’s equipment is going to hold up.

Let’s get another thing straight. Buying a Freeride bike does not make you any better.

Do not confuse the built-in capabilities of equipment with your own capabilities, which

must be learned.

Keeping your bike and all its components in good working order is critical, and it’s up

to you to maintain and inspect it. Even so, your sweet rig isn’t going to last forever.

Nothing does, particularly bikes and parts that are built to minimize weight and then

are subjected to abuse. Cannondale frames carry a warranty, but that’s to cover issues

with workmanship and/or materials. (See the Cannondale Warranties section of the

Owner’s Manual.) The warranty doesn’t mean that they’re going to last forever. They’re

not. The warranty certainly doesn’t mean that the bicycle can in any way protect you

from injury.

In Conclusion

If you’re going hard-core, be smart about it. Always wear a full face helmet, body armor,

full-ﬁnger gloves and protective clothing. Choose a bike that’s right for you, your riding

and terrain, and check it often for signs of fatigue or other trouble. (Your dealer can help

you on both fronts.) Read the Mountain Bike Riding section of the Cannondale Bicycle

Owner’s Manual. And most importantly, know your limitations. Practice. Stay in control,

and carefully, gradually expand your limits – but ride within them.

LATERAL

1. Chainstays - The custom-formed and tapered chainstays are

optomized for lateral stiffness. Tuned for vertical compliance, they

distribute stress evenly under extreme landing loads.

2. Hot Box Pivot - Constructed as a welded, Hollow-Core swingarm pivot. It

is designed for maximum stiffness and minimum lateral ﬂex. It’s CNC -

forged hollow core provides a tremedous stiffness-to-weight ratio, boosting

stifness by up to 30% which prevents wagging and increases pedal efﬁciency.

The rear derailleur cable is routed internally through the Hot box and

within the chainstays, delivering a clean look and no ghost shifting.

3. Pivot Assembly - This assembly features a precision pivot

shaft and renewable sealed cartridge bearings.

maximum fork length

Maximum Fork Length is an important frame safety testing speciﬁcation. You must

observe the measurement when installing headset parts, headset adapters, installing

and adjusting a fork, and replacement forks. The speciﬁcation is printed on a warning

label indicated in the ﬁgure below. In this manual, the number is also listed in the

specifications section.

HEADTUBE

HEADSET

PARTS or

ADAPTERS

WARNING

DO NOT INSTALL HEADSET PARTS OR FORKS RESULTING IN A MAXIMUM FORK LENGTH

LONGER THAN THE SPECIFICATION FOR YOUR FRAME. DO NOT ADJUST A TRIPLE CLAMP FORK

SO THAT MAXIMUM FORK LENGTH EXCEEDS THE FRAME LIMIT. Exceeding the MAXIMUM

FORK LENGTH limit can overload the frame causing it to fail (break) while riding.

YOU CAN BE SEVERELY INJURED, PARALYZED OR KILLED IN AN ACCIDENT

IF YOU IGNORE THIS WARNING.

HOW TO MEASURE:

1. Temporarily install the

fork into the headtube

with the headset/

adapter in use.

2. Fully extend the fork.

If the fork is a triple

clamp type, extend

the legs to maximum

designed length.

3. Measure the distance

from the bottom of

the head tube to the

center of the wheel

axle.

Do not measure from

the bottom of headset

bearing cups or head

tube adapters. The

measurement MUST be

taken from the bottom of

the head tube!!

line and cable frame

protection

Normal line and cable movement against

the frame can wear away painted ﬁnishes

and decals. Overtime, cable rubbing can

wear into the frame itself causing very

serious frame damage.

Check over your bike after your ﬁrst few

rides. Apply a clear adhesive guard

material in areas where rubbing is found.

When applied correctly, clear guards are

good protection for your bike.

Cannondale

Kit # KF103/ (8 PK)

To apply the guard material

(included with your bike):

1. Clean the frame with a mild detergent

and wipe dry with a clean towel. Do not

use solvents or harsh chemicals to clean

the frame. OPTIONAL: Trim the adhesive

guard material to the shape required.

2. Remove the backing and position the

guard under the cable/ line.

3. Rub the guard ﬁrmly against the frame

with your ﬁngers to ﬁx it in place.

4. Periodically, recheck the guards and

other areas of the frame as you continue

to ride. Replace the guards if they wear

out.

PLEASE NOTE:

Damage to your bike caused by cable

rubbing is not a condition covered under your

warranty. Also, adhesive frame guards are

not a ﬁx for incorrectly installed or routed

cables or lines. If you ﬁnd that applied guards

are wearing out very quickly, consult with

your Cannondale Dealer about the routing

on your bike.
