The new standard in internal geared hubs

TThe NEXUS 8-speed system delivers a new level of design, quality and function. Our designers have updated

the conventional internal hub with a refreshing new design inspired by the concepts of beauty, innovation

and integrity. Many technical advances have been achieved, like incorporating Shimano’s unique gear

change support mechanism that makes a real low effort shifting.

The INTER-8 hub has increased its gear ratio to 307%,

compared to 244% of the INTER-7 hub. The INTER-8 hub

also incorporates a closer gear ratio allowing a more

efﬁ cient and comfortable pedaling cadence.

A truly “all conditions” internal hub has arrived.

Equipped: SHIMANO ALFINE/SHIMANO NEXUS INTER-8

The table above shows the relative gear ratio for the INTER-7

and INTER-8 gear hubs when used with a 20T sprocket.

The numbers in parenthesis show the sprocket size that each

gear ratio corresponds to in a derailleur system.

Previous shifting systems shifted faster in one direction

than the other. Choosing top normal or low normal always

meant sacriﬁ cing shifting speed in one direction.

Now with MULTI RELEASE you can release shift two gears

in one stroke. The result - the fastest possible shifting in

both directions regardless of rear derailleur choice.

Pushing up the release lever

MULTI RELEASE

The OPTICAL GEAR DISPLAY tells you which gear position

is selected while riding your bike. You can see how many

gears you can select either on the low side or top side,

which makes shifting control easier.

SHIMANO gear change support mechanism utilizes some

portion of pedaling force at down shifting. The result is a

quick and precise downshift with very light feeling. For

the automatic shifting system, this gear change support

mechanism is the key. Shifting effort is reduced to the

point where the hub can be shifted through a small

low-torque DC motor. Less electricity is required, so a

smaller battery allows the system to be lighter and more

compact.

HYPERGLIDE+ dedicated chain delivers greater chain

retention, improved shifting efﬁ ciency, and smoother

transmission over rough terrain.

Revamped HG chain features an extended inner link plate

that connects seamlessly with new chainring tooth shape

for ultra-efﬁ cient drivetrain performance.

This design change reduces the vibrations normally

caused by the inner and outer chain plates rolling onto

the chainring, and provides better chain engagement,

stronger retention, and smoother pedaling.

HG

The inner outer plate, designed for better contact with

gear teeth, allows smooth shifting even under high load

conditions. In addition, the chain has achieved a pedaling

efﬁ ciency of 0.6% higher.

In order to obtain good gear shifting performance, this

chain has a forward side and a reverse side, and the sides

are marked so that the chain will face the correct way

when installed.

The distinctively designed HYPERGLIDE sprockets

incorporate specially positioned shift ramps and tooth

and responsive indexed shifting is the result.

The HG cassette sprocket, which was developed for the

MTB 10-speed system, underwent comprehensive

optimization to achieve super-highly efﬁ cient shifting.

HG-EV cassette sprocket is for

rider-tuned gear combination &

provide optimal 11-speed

Labyrinth & contact seal (road)

Speciﬁcally designed seals inside the hub shut out mud,

dust, dirt and moisture and protect the bearing

mechanisms, realizing low maintenance as well as longer

service life.

This maintains the original performance for a longer

period of time under unfavorable environmental

conditions.

The 9-speed gear cluster actualizes close ratio gearing

without impairing wide gear range.

Light pedaling with efﬁcient drivetrain

• Optimal gear ratio for each wheel size

The larger the wheel the more range needed in the

cassette to maintain light pedaling.

• Refined front shifting system

Gear combinations specialized for each tire size reduces

the number of recovery rear shifts needed with front close

gear ratio.

• Tire clearance improved for better maneuverability

Compared the power transfer of OCTALINK with the

interface that connects bottom bracket and crank set

increases the strength and rigidity for entire assembly.

To meet customer needs in the

best possible way, SHIMANO

has developed the press-ﬁt

bottom bracket, staying

focused on our ﬁnal goal: total

performance in pedaling.

The bottom bracket axle is

steadily supported by the wide

placed bearings on the basis of

TECHNOLOGY

Road disc brakes deliver consistent brake performance in

any weather, with lighter lever action and greater brake

power control for a wide range of riding styles.

Hydraulic disc brakes can expand the riding possibilities by

meeting and exceeding the expectations of a wide range

of riders, from traditional road to unconventional styles

like gravel and adventure road. SHIMANO road disc brakes

can make riding more enjoyable for a wider range of

riders because of its consistent brake performance

unaffected by weather conditions, lighter lever operation,

easier brake power control, and the superior heat

dissipation performance of ICE TECHNOLOGIES.

SHIMANO multi-condition roller brake use a precision cam-

controllable braking power. Large disc-type radial cooling

service life of the lubricant. Sealing channels keep out dirt

and water to assure safe and dependable braking

performance in wet or dry conditions.

Equipped: SHIMANO NEXUS/SHIMANO TOURNEY

Multi-Purpose Roller Brake

With the adoption of a V-shaped brake shoe and larger

cooling ﬁ ns, the braking force is closer to that of a

mechanical disc brake. The V-shaped brake shoes increase

braking power while the large ﬁ n raises heat dissipation

efﬁ ciency that allows it to brake longer and harder

without fading. These upgrades make the roller brake

more suitable for a wider variety of bicycles.

Equipped: BR-C6000/C3010/C3000

When you pull a SERVO WAVE brake lever, initial pad

travel is fast, so little lever movement is needed to bring

the pads into contact with the disc brake rotor.

The power multiplication factor then increases rapidly at

the pad-to-rim contact so more of the lever stroke is used

to apply greater braking power with improved control.

WARNING

•

When securing the brake arm to the frame,

be sure to use a brake arm clip that

matches the size of the chainstay, and

securely tighten them with the clip bolt

and clip nut to the speciﬁed tightening

torque.

•

Use a lock nut with a nylon insert

(self-locking nut) as the clip nut.

•

It is recommended that Shimano made clip

bolts, clip nuts, and arm clips be used.

•

If the clip nut comes off the brake arm, or

if the clip bolt or arm clip becomes

damaged, the brake arm may rotate on the

chainstay and cause the handlebars to jerk

suddenly, or the bicycle wheel may lock

and the bicycle may fall over, causing

serious injury.

NOTICE

•

If it is not installed correctly, braking

performance will suffer. Be careful not to

apply excessive force when installing.

•

If excessive force is applied to the brake

arm to secure it, the wheel will make noise

and become difﬁcult to turn.

•

After installing the arm clip, check that the

clip bolt protrudes about 2 to 3mm from

the end face of the clip nut.
