THE DUALDRIVE SYSTEM
W H AT I S D U A L D R I V E
The general perception is that shifting requires a Zen-like touch from years of trial and error . . . mostly error. Many riders wanted something easier. We really love this kind of challenge. And DualDrive exceeds all the expectations. DualDrive is a drive train consisting of a self-energized internal hub and rear derailleur for smooth adjustment. It's the market's most revolutionary transmission.
RIDING MODES
DualDrive has 3 intuitive shifting modes. Hill mode, standard mode, and fast mode. Each mode is designed to allow the rider to be in the proper mode wherever you go.
Hill
O P E R AT I N G P R I N C I P L E
Single-side shifting allows the rider to use one-hand to easily click through a 27-, 24- or 21 gear option. And DualDrive's superior gear indication, featuring three intuitive riding modes, creates a smooth, comfortable ride for novice and masters alike. Easy shifting. Advanced performance. Mission accomplished.

THE DUALDRIVE SYSTEM
E
DualDrive hub and cassette Super light shifting forces, load shiftable. Stand-still shifting (mode selector): easy re-start at a traffic light
DualDrive single-sided shifter Simple gear indication: one view for all information. Intuitive logical shifting.
DualDrive Clickbox Easy wheel removal: pre-adjusted gears for simplicity.
DualDrive rear derailleur Light, precise shifting. Larger pivots, links and cages: increased rigidity and durability.

THE DUALDRIVE SYSTEM
HOW LONG DID IT TA K E T O F I N I S H DUALDRIVE?
A big team of 25 engineers from all around the world worked for two years on this project. » Shifter with Clickbox: 27 speed with gear indication window or 24 and 21 speed without gear indication window. » Spoke protector: There are two versions available: in versions for 36 or 32 spoke hole hubs. » Crank: DualDrive cranks offer the best performance with the DualDrive system.
HOW DID WE TEST DUALDRIVE?
Enthusiastic trekking riders did test the system under all weather circumstance for more than a year. Within these tests we finetuned the function of the system to perform to 100% of the comfort trekking riders expectations.
I BELIEVE A DUALDRIVE SYSTEM HAS TO BE HEAVIER THAN A NORMAL EXTERNAL DRIVE SYSTEM!
In fact the DualDrive system weighs around 250 gr less than a standard derailleur drive train system.
W H AT PA R T S D O I N E E D TO COMPLETE A DUALDRIVE TRAIN?
A DualDrive train contains the following products: » DualDrive hub: in either without brake and disc brake version. » Cassette: 11-34 teeth, 9 speed for DualDrive 27 or 11-32 teeth, 8 speed for DualDrive 24 or 12-32 teeth, 7 speed for DualDrive 21. » Derailleur: DualDrive 9 speed for DualDrive 27, DualDrive 8 speed for DualDrive 24 or DualDrive 7 speed for DualDrive 21.
W H AT I S T H E B E N E F I T OF THE SINGLE SIDED SHIFTER?
It is more intuitive due to the riding modes which explain the driver directly what mode to use in which terrain.

MAINTENANCE AND CARE GEAR ADJUSTMENT
Chain gap adjustment: Chain gap is the distance between the upper guide pulley and the cog the chain is riding on. Optimal chain gap allows quick, efficient shifts. » While turning the crank, push the rear derailleur inboard by hand to the largest cog. » Hold the derailleur in this position while making the following adjustment.

6 mm (1/4")
3 mm

Use a 3 mm hex wrench, turn the b-adjust screw until the chain gap equals approximately 6 mm (1/4"). Â Turn the b-adjust screw clockwise to increase the chain gap. Â Turn the b-adjust screw counterclockwise to decrease the chain gap.
Do not use the b-adjust screw to adjust the rear derailleur to act as a chain-tensioning device or to prevent chain suck. This increases the chain gap causing poor shifting performance.
» Shift the chain to the second cog.  If the chain hesitates or does not shift, increase the cable tension by turning the shifter barrel adjuster counterclockwise.  If the chain shifts beyond the second cog, decrease the cable tension by turning the shifter barrel adjuster clockwise. » Repeat the two former steps until shifting and cable tension is accurate. » While turning the crank, shift the chain up and down the cassette several times to ensure that your derailleur is indexing smoothly.
Index shifting adjustment: » Make sure the chain is located on the smallest sprocket. DualDrive · December 2002

MAINTENANCE AND CARE C L E A N I N G A N D L U B R I C AT I O N
CLEANING
Your DualDrive components are well protected against adverse environmental influences. In order to avoid malfunction due to water penetration, pressurized jets (high pressure cleaners etc.) should not be used when cleaning the bicycle. » When using the bike during the winter more frequent cleaning is necessary to prevent damage caused by de-icing salt. » Do not use solvants or corrosive materials to clean the components. » Clean dirty chains before oiling. Do not use any grease-dissolving or acidic agents. Cleaning agent must be rinsed off after a few minutes with water. Apply oil after chain is completely dried.
