WARNING: Never shift a derailleur 

onto the largest or the smallest 

sprocket if the derailleur is not shifting 

smoothly. The derailleur may be out of 

adjustment and the chain could jam, 

causing you to lose control and fall. 

Which Gear Should I Be In? 

The combination of largest rear and smallest 

front gears is for the steepest hills. The small-

est rear and largest front combination is for 

the greatest speed. It is not necessary to shift 

gears in sequence. Instead, find the “starting 

gear” which is right for your level of ability — a 

gear which is hard enough for quick accelera-

tion but easy enough to let you start from a 

stop without wobbling — and experiment with 

upshifting and downshifting to get a feel for the 

different gear combinations.  At first, practice 

shifting where there are no obstacles, hazards 

or other traffic, until you’ve built up your con

-

fidence. Learn to anticipate the need to shift, 

and shift to a lower gear before the hill gets too 

steep. If you have difficulties with shifting, the 

problem could be mechanical adjustment. See 

your dealer for help. 

How an Internal Gear Hub 

Drive Train Works

If your bicycle has an internal gear hub drive 

train, the gear changing mechanism will consist 

of: 

A 3, 5, 7, 8 or possibly 12-speed internal 

 

»

gear hub.

One, or sometimes two shifters.

 

»

One or two control cables.

 

»

One front sprocket called a chain ring.

 

»

A drive chain.

Shifting Internal Gear Hub Gears 

Shifting with an internal gear hub drive train 

is simply a matter of moving the shifter to the 

indicated position for the desired gear. After 

you have moved the shifter to the gear position 

of your choice, ease the pressure on the ped-

als for an instant to allow the hub to complete 

the shift.  

Which Gear Should I Be In?

The numerically lowest gear (1) is for the 

steepest hills. The numerically largest gear (3, 

5, 7 or 12, depending on the number of speeds 

of your hub) is for the greatest speed.
