INTENDED

For cross-country riding and racing,

intermediate terrain (e.g., hilly with small

obstacles like roots, rocks, loose surfaces and

hard pack and depressions, relatively short

suspension travel, supporting nimble handling

NOT INTENDED  DO NOT USE:

No large drops, drop-os, wooden structures,

or dirt embankments requiring long

suspension travel or heavy duty components

and hard landings.

For Extreme forms of jumping/riding (e.g.,

hard core mountain, Freeriding, Downhill,

North Shore, Dirt Jumping, Hucking).

No Tandems

No Motorcycles

No Engine powered vehicles

Using the Lefty the wrong way is

dangerous.

Please read your Cannondale Bicycle

Owner’s Manual for more information

about Intended Use ASTM Conditions 15,

and riding conditions deﬁned by each.

The intended use and riding conditions

deﬁned by on-product markings and

owner’s manual for the speciﬁc Lefty fork

model MUST match those of the frame.

A mis-match between a Lefty fork and a

frame can lead to failure of the frame or

Lefty fork. Such a failure can lead to a loss

of control, with the risk of serious injury or

death to the rider.

If you have any questions consult a

Cannondale Dealer or professional bike

mechanic with experience in Intended Use

conditions in the bicycle industry.

You can be severely injured, paralyzed

or killed in an accident if you ignore this

warning.

Safety Information

Important Composites Message

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.

Crash/Impact Damage

Inspection

After A Crash Or Impact:

Inspect the entire bike, all parts; Look

carefully for damage. See “Inspect For

Safety” section in the Cannondale Bicycle

Owner’s Manual. See Support at www.

cannondale.com

Any of the following conditions indicate

that serious fork damage is present:

• Any “klunking,” creaking, knocking or

unexplained noises.

• A change in travel, and/or function.

• Loss of adjustment features, oil or air

leaks, or loose/broken parts.

• Crash or impact damage (cracking,

deep scratches, gouges, dents, or

bending)

• Carbon which has a soft feel or

altered shape, or broken, splintered, or

delaminated carbon ﬁber.)

• Visible cracks, a white or milky color

present in carbon ﬁber section

Continuing to ride a damaged frame /

fork increases the chances of frame /fork

failure, with the possibility of injury or

death of the rider.

Safety Information

Minimum Tire-to-Crown Clearance

Minimum Tire-to-Crown

Clearance

Modiﬁcation or installation of damping

cartridge/spacers other than speciﬁed; or

installing over-sized tires can result in

incorrect tire-to-crown clearance

Check minimum tire fork/frame

clearance with all air released from lefty

and fully compressed.

Measure between the top of the properly

inﬂated tire (1) and the bottom of the fork

crown (2).

≥ 3mm

If tire clearance is less than the minimum

speciﬁed, the rotating tire could come into

contact with with the fork crown or frame

causing the wheel to stop suddenly. This

can throw a rider o the bicycle or result in

a loss of control and crash.

Compression Assembly

55mm

For carbon steerer models, use only the

headset compression assembly (1)

speciﬁed for the model. See

“Speciﬁcations.”

Do not use other headset compression/

preload adjusters, shims, and do not

modify the steerer.

Do not Stack spacers (3) on top of the

stem (2) or exceed the 55 mm Maximum

Stack Height (total spacer height stacked

between the top of the head tube (5) and

the stem (2). Exceeding maximum stack

height with spacers (3) or locating spacers

on top of the handlebar stem can place

signiﬁcant stress on the steerer tube (4). It

could break.

Follow the Cannondale compression

assembly installation instructions.

Use a torque wrench to tighten. Follow

stem manufacturer’s torque speciﬁcations.

Safety Information

Front Brake

Making External Adjustments

Make any external adjustments only when

stopped. Attempting to adjust while riding

can result in a loss of control.

You can be severely injured, paralyzed, or

killed in an accident if you ignore these

warnings.

Disassembly or Modiﬁcation

Modiﬁcations can lead to serious fork

damage or serious personal injury.

Do not modify the Lefty in any way.

Use only original equipment (OE)

replacement parts. See “Replacement

Parts.”

Do not attempt damage repair yourself.

Have any required repair services or

procedures perform by an Authorized

Cannondale Dealer or Cannondale

Authorized Service Center.

You can be severely injured, paralyzed

or killed in an accident if you ignore this

warning.

Front Brake

The brake mount (1) is compatible with post

-mount type brake systems.

Before riding, make sure the StopLock

release lever is in the locked position

(shown). See “Front Wheel” removal and

installation instructions.

Follow brake manufacturer’s instructions

when mounting the brake caliper.

Do not ride without a front brake system

attached to the Lefty. A brake system

(disc/caliper) is an important secondary

wheel retention system. If the brake

system is missing or improperly installed,

and/or if the wheel hub axle bolt should

loosen, the front wheel could slide o the

spindle end.

You can be severely injured, paralyzed,

or killed in an accident if you ignore this

warning.

Technical Information

Adjustments

Air Pressure

Set the initial air pressure according to your

weight (including the weight of riding gear)

based upon the following table. Then, adjust

air pressure in small amounts for your riding

preference.

Adding more air will result in a stier

suspension feel. Less air pressure will result in

a softer suspension feel. Stay within the

minimum and maximum air pressure limits.

Figure 2

To set air pressure:

1. Clean the area around the valve and the

pump end to remove dirt or contaminants.

2 Remove the valve cap (1), attach a

high-quality suspension pump to the valve

(2) .

3. Pressurize to the recommended air

pressure

4. When completed, remove the pump;

replace the valve cap.
